Background technique
Vertical shaft impact crusher is the crusher for having used the working principle entirely different with conventional breakers, impingement
Rotor reaches the speed of 60m/s or more with 1500 revs/min or so of high speed rotation, rotor edge linear velocity, from center pan feeding, leads to
Cross by can broken material accelerate to the up to speed of 60m/s or more, hit iron wall liner or cliff lining, reach it is broken can broken material
Purpose, " vertical hammer broken " or " vertical anti-broken " effect than laying particular stress on from side blanking and being difficult to improve speed is far better, special
Be not centering granule can broken material crushing effect it is preferable.
Vertical shaft impact crusher includes rack, motor, motor rack, upper feed hopper, rotor, middle part, central cavity, master
Shaft assembly, pulley assembly, lower part etc..Rack is mounted on ground or certain structural buildings for bearing main screw lift, by firm
In;Rack usually passes through with host and can play the vibration isolator of vibration isolation and couple.Motor is mounted on motor rack, and motor passes through motor
Belt pulley, belt, spindle pulley, impart power to main shaft, and main shaft high speed rotation drives the impact for being mounted on main shaft top
Type rotor high speed rotation.For bearing, spindle assemblies, bearing middle part, accept can broken material etc. for host lower part.It is used in the middle part of host
In bearing host top, central cavity is installed.Central cavity be used to accept rotor dishes out can broken material, broken make occurs
With.Host top is equipped with feed hopper, and feed hopper has simple bucket and two kinds of overflow downcomer, can fragment for accept Belt Conveying
Material or other means conveying can broken material, simple bucket only accept can broken material, will by the feeding pipe for the bottom centre that struggles against
Can broken material be sent to high-speed rotating impact rotor central part, there is the tune of adjustable opening size in overflow downcomer bottom centre
Plate is saved, periphery is provided with transfer window, and when reducing overflow downcomer bottom centre hole size, supplied materials will be accumulated in hopper, reach one
After determining height, the strike region that part enters rotor periphery from peripheral overflow mouth will exceed.Into rotor center can fragment
Material, rotor drive can broken material rotation after, through projectile channel from cast mouth high speed dish out.
The high speed that rotor is cast out can broken material, will main strike on the central cavity that rotor corresponds to circumference range,
It is broken that strike shock occurs.Bear high speed can broken material hit cavity siding can wear, in order to protect middle part body
Shell protects cavity siding using wear-resistant material, supports the structure of wear-resistant material or independently couples with central enclosure, or
One entirety couples again with central enclosure, it is preferable to use overall structure.Wear-resistant material is higher than common material hardness, also there is certain thickness
Degree correspond to range and surrounds circumference, substantially seamlessly bears high-speed material impact, generation fragmentation in rotor material of dishing out.
Initial central cavity wear-resistant material is to be similar to arc-shaped, surrounds ring-type.In order to improve crushing effect, and then will
Plate bulk is made in wear-resistant material on one side, claims chopping block, will bear scope of attack opposite direction materials casting direction, so that material and chopping block are sent out
Raw positive or close forward direction is hit, and than other non-positive shocks, crushing effect is more preferable for this positive or close positive shock.This anvil
The cavity and fragmentation that plate is formed are known as " stone forge iron type chamber ", this type chamber broken material lower to medium hardness and abrasion
Expect that effect is fine, but to more than medium hardness and the broken material of high abrasion, the loss of wear-resistant material is too fast, and cost is excessively high,
Bad economic results are allowed to, and are replaced frequently, downtime is long;And " stone forges iron " may also can generate excessive mountain flour, most of fields
Conjunction causes to waste;Again rotor dish out can broken material distribution equivalent is distributed not instead of in rotor outlet height, it is a kind of
Normal distribution.In order to overcome the problems, such as that it is excessive that " stone forge iron type chamber " wear-resistant material is worn, industry has " stone-crash-stone type chamber " appearance again,
Dish out in rotor and the L-shaped cyclic structure in section surrounded with steel plate on the corresponding circumference of material, can broken material fall in L shape, press
The sloping ring-type of angle of repose heap, claim " stone-crash-stone chamber ", also known as " stone lining chamber ", it is subsequent can broken material will hit herein " stone lining "
On, the crumbling method of " stone-crash-stone " is formed, this mode overcomes " stone forges iron " high the shortcomings that wearing, adapts in various hardness
And the broken material of high abrasion.But in contrast, crushing efficiency decline is more, and on the one hand " stone lining " is loose or hardened side
Formula has certain absorption kinetic energy effect, and on the other hand, projectile material and " stone lining " are oblique shocks, is not nearly positive shock.
The height of anvil in " stone forge iron type chamber ", for having top plate, material enters from rotor center position, from
Rotor center, which leads to edge, several materials casting channels, casts channel height by height limitation, object between rotor upper and lower bottom plate
Material is dished out from this channel, and corresponding surrounding strike altitude range is no less than this and casts channel height, and because casts also oriented
The angle of outer diverging, it is usually higher than casting channel height, so corresponding " stone the forge iron type chamber " anvil of use " enclosed rotor "
Height not less than rotor cast channel height cast the dispersion angle of material for " open rotor " of not top plate
Bigger, it is higher that anvil height usually casts channel height than rotor.But cast from rotor can broken material height point
Cloth not instead of equivalent is distributed, a kind of normal distribution, so the part at anvil height both ends causes to waste using less.If
The height of anvil is lower than rotor channel height, then has partial material that will hit the structure other than anvil, so, there must be other guarantor
Protection structure, but do not have the structure for rationally utilizing anvil also.It is a kind of standard to the height of the anvil in " stone forge iron type chamber " above
Really description, in practice, because of the presence of scattering angle material, the height of anvil is similar to rotor height or is higher than rotor
Highly, " casting channel height " or " rotor may be used in the description of the anvil height in " stone forge iron type chamber " later
Highly " two ways, difference can be disregarded in practice.
In order to improve the crushing effect of both the above type chamber, in CN200520046856.9, in a circumferential direction, some
Segmental arc is set as anvil plate, some segmental arcs are set as stone lining chamber, to change in the changes of two kinds of cavity different proportions of circumferencial direction
The fineness modulus and content of stone powder of kind finished product, reduce unnecessary abrasion.But such cavity still has more waste, because casting
Can broken material normal distribution, keep the intermediate abrasion of anvil more and be replaced one integral piece anvil, although can be carried on the back in anvil
Face is designed to closely wait the thickness of abrasions, but still has the wear-resistant material of more valuableness to be replaced waste.And in such design, stone lining chamber
It can only determine in advance with the ratio of anvil chamber, Operating condition adjustment can not be pressed at the scene.This chamber circumferential portion is " stone lining chamber ", part
It is " anvil chamber ", can be described as " circumferential mixing chamber ".In CN201220636591.8, iron is installed on the back top of stone lining chamber
Chopping block, the anvil plate designed in this way, actually utilization rate are also lower, because the position close to middle housing is arranged in its anvil
Set, position is remoter from rotor, projectile can broken material speed decline it is more, crushing effect decline it is more.Top anvil site
Rearward, stone lining height is higher, positioned at cast can broken material normal distribution axis separate side, fragmentation compared with
It is low, and it is far from rotor, material is after rotor is dished out, and because of factors such as windage, gravity, flying speed begins to decline, and distance is got over
Far, speed decline is more, and crushing effect is poorer.By this patent document specification and Figure of description, the anvil of this structure is
Cyclic form is surrounded, emphasis is protection body fuselage, does not form the nearly positive effect hit, reinforcement also only increases iron thereon
The rigidity of chopping block forms bolt mounting surface and protects the effect of installation bolt, also not formed positive shock.This chamber top is
" anvil chamber ", lower section are " stone lining chambers ", can be described as " upper and lower mixing chamber "
Also some cavity effects in the market place anvil by rear portion in stone lining chamber L-type, and the purpose is to can be pacified by anvil
Dress and remove, converted between " stone forges iron " and " stone-crash-stone " two kinds of cavitys, in this way design, type chamber convert be it is more convenient,
But drawback is it is also obvious that the effect of its " stone forges iron " is weakened because other designs may be all of the occasion of anvil, this
The middle lower section of anvil is by stone lining institute " burying " in chamber, is still the effect of " stone-crash-stone ", anvil using insufficient, substantially under
Half portion is not worn, and top is also worn less, once abrasion in the middle part of anvil, one integral piece anvil is just abandoned, and wastes very big.Such chamber
It is stone lining in front of rotor, the rear far from rotor is " anvil ", can be described as " front and back mixing chamber ".
Summary of the invention
The invention discloses vertical shaft impact crusher central-axis type iron-stone mixing chambers.In order to improve vertical shaft impact crusher
Crushing efficiency, improvement can broken material fineness mould degree, reduce content of stone powder, reduce the steel abrasion loss of finished product per ton, and improve
The adjustment flexibility at scene, can in height abrasion can be in broken material, tradition can only use the occasion of " stone-crash-stone type chamber ", increase
Few as far as possible wear-resistant material abrasion, improve the using effect of hereinbefore several " mixing chambers ", reach close to " stone forge iron type chamber "
Crushing effect, entire crushing production line can be made, play whole abilities of other machinery equipments, final products yield is improved, change
It is apt to the output proportion of each final products, is allowed to more rationally.And adjustment height in scene is provided, front-rear position and subsequent adjustment highly,
The flexibility of thickness, front-rear position, and can be according to Different field, different operating condition flexible transformations between various type chambers.
The technical scheme is that the high efficiency in order to utilize " stone forge iron type chamber ", improves the broken of former " stone lining chamber "
Effect, according to cast can broken material normal distribution, this mixing chamber anvil is that the former rotor that is usually less than casts channel height
" stone forge iron type chamber " anvil about 20%~70% height, it may be assumed that this mixing chamber anvil is that rotor casts the 20% of channel height
~70% height, this anvil height middle line and projectile can the normal distribution central axes of broken material essentially coincide, dish out in rotor
At L-shaped ring-type is still enclosed with steel plate on the corresponding circumference of material, anvil is in the encirclement of this L shape.Because anvil height middle line and projectile can
Overlapping of axles in broken material normal distribution can be described as " central-axis type iron-stone mixing chamber ".But the flexibility of its great lumen type transformation,
Also has the functional effect of " circumferential mixing chamber " simultaneously.
The height of this anvil can be cast in 20%~70% height of channel height in rotor to be changed.20%~70% anvil
Height determines that principle is that anvil is shorter, then wear-resistant material utilization rate is higher, and anvil is longer, then crushing efficiency is closer to " stone is beaten
Iron " efficiency.And above and below this chamber anvil, still form stone lining, this range projectile can broken material, be still that " stone is beaten
Stone " effect, by cast can broken material normal distribution curve, far from axis ratio it is less, although being herein " stone-crash-stone "
Effect, but it is most of can broken material be fall in cast can broken material normal distribution curve near axis, so, be crushed effect
Fruit is close to " stone forges iron " effect, but the utilization rate of anvil improves a lot.The determination of final anvil height, can sentence in advance
It is disconnected, it is determined when manufacturing, the effect that live can also make different height compares, and finally determines optimum height, and in subsequent anvil
It is provided in component by this height.User can obtain best between anvil utilization rate, abrasion cost, percentage of damage, fineness modulus
Cost performance.
At this point, there are also a kind of efficient crumbling method, what " stone forges iron " sprang back can broken material in addition to the effect that stone forges iron
Formed part " stone-crash-stone head-on collision " effect, this " stone-crash-stone head-on collision " be not can broken material and fixation stone lining shock,
Instead of cast can broken material with from top overflow drops down the freely falling body without horizontal velocity can broken material bump against, have
The shock of the rebound material and projectile material of certain speed, this shock, effect is more preferable, and wear-resistant material is not lost, and is more to occur
At " stone forge iron chamber ", and be dish out can near the axis of broken material normal distribution, just can relatively mostly occur it is this hit it is broken.
Near axis can broken material hit anvil after, substantially rebound vertically, rebound route with projectile route it is Chong Die, Jiu Huifa
Raw " stone-crash-stone head-on collision " effect, and here, can the broken material density that casts and spring back it is very big, the probability of shock is very big.?
Position far from normal distribution axis, can broken material be that bevel and anvil are hit, can after broken material and anvil hit, at
Symmetry angle reflects away, and does not overlap with projectile material tube line, seldom has an opportunity to hit, and its density is smaller, hits
The probability hit is also smaller.If material abrasivity is stronger, anvil height can be reduced, while bears anvil unit area more
More can broken material shock.Closer to cast can broken material normal distribution curve axis, " stone-crash-stone head-on collision " effect gets over
By force, although material abrasivity improves more by force steel consumption, herein, the utilization rate of unit area is very high, the broken finished product effect of raising
Benefit will be more than that steel consumes.
It dishes out in rotor and the L-shaped cyclic structure in section, L-shaped close rotor is still surrounded with steel plate on the corresponding circumference of material
Inside usually there are also a circle seam allowance circle, protects bottom plate, also shapes stone lining securely, is not easy to be blown by the high wind that intracavitary rotor is formed
It dissipates.Can broken material fall in L shape, by the sloping ring-type of angle of repose heap, space of the anvil in the encirclement of this L shape, below anvil
Stone lining is still formed, for the stone lining below anvil close to vertical angle, " the stone-crash-stone type chamber " described in front is formed by stone lining,
Be by material angle of repose formed can broken material entity lining, angle of repose usually between 30 degree to 40 degree, individual materials glue
Property is stronger, will form the angle of repose greater than 40 degree, this operating condition is less.And can broken material cast direction be level side mostly
It oblique between broken material and stone lining can hit poorer than 90 degree of positive impact effects to, this projectile, and expect without rebound
" stone-crash-stone head-on collision " effect, now, the spatial altitude below anvil is shorter, and stone lining is easy to be piled into narrow space to be connect
It is bordering on 90 degree of vertical cliff lining, thus " stone-crash-stone head-on collision " effect for reaching close to positive impact effects, and also thering is rebound to expect
Fruit, this belongs to subsidiary increase crushing effect.
The mode as forming " central-axis type iron-stone mixing chamber "+" circumferential mixed type chamber " using dismounting part anvil,
Because circumferential width shared by anvil is relatively narrow, stone lining is also easy to accumulate, the angle of repose of the stone lining stocking angle of formation than free state
Big, stone lining is stronger, is less susceptible to be broken up, be dispelled by whirlwind, the crushing effect of shock is more preferable.
Stone lining above anvil, " stone-crash-stone " stone lining originally, close to chamber ring and superposed stone lining, thinner thickness,
Accumulate firmness it is limited, high-speed projectile can broken material strike under, often broken up, dispelled by whirlwind, be in a kind of loose heap
Long-pending state, be easy to absorb resolution cast can broken material kinetic energy, to reduce fragmentation.The position of present anvil is prominent
It except former stone lining angle of repose entity, is equivalent to and forms interlayer in the middle and upper part of type chamber, increase the type chamber annular of top stone lining
Width, the stone lining of accumulation still press angle of repose accumulation, but because width increases many, the thickness of stone lining also increases very much, the jail of stone lining
Soundness increase it is very much, this stone lining closer to rotor, cast can broken material speed decline it is less, to improve broken effect
Fruit.Although with the abrasion of anvil, this stone lining also can reduced thickness, also the stone lining very thinner than originally is stronger, and crushing effect is more
It is good.
Anvil height and position adjustment flexibility, that is, anvil height and position be it is adjustable, in principle in the height of anvil
Line should with cast can the normal distribution curve axis of broken material be overlapped.Cast can broken material normal distribution curve axis it is logical
It is often overlapped with the height middle line of rotor, but may be also different, different by rotor size, structure, depth, feeding coal is different, in
Heart sub-material cap shaped difference etc. influences, rotor height middle line with can the normal distribution curve axis of broken material usually occur centainly
The offset of amount.Different field working conditions are different, when design height middle line with normal distribution axis in actual use simultaneously
Not necessarily it is consistent, therefore, the height of anvil should can be adjusted according to Different field, in addition to can be in the design rank before the manufacturing
Section is judged, is adjusted accordingly outside, also be can adjust at the scene, and after initial use, and it is single that using effect feeds back to manufacture
Position, it is subsequent to can provide anvil component adjusted, even if the use site that replacement is different, still can neatly adjust.User can
To obtain best cost performance between anvil utilization rate, abrasion cost, percentage of damage, fineness modulus.
Anvil is also the factor for influencing crushing effect with a distance from rotor, can install, can also move back in former anvil site
Position is installed afterwards, is essentially to be exposed to anvil except the stone lining of lower section, i.e., except the entity area that the angle of repose of stone lining is formed,
And this stone lining is because of various material varieties differences, moisture content is different, viscosity is different, composition gradation difference, the angle of formation is also different,
Therefore be difficult to determine anvil site in advance, herein, by the way of flexible adjustable position, allow the position of anvil by scene
Requirement adjust.If material abrasivity is not that too by force, then anvil can be made close to rotor, the material speed for making rotor dish out is because of wind
The decline of the factors such as resistance, gravity is less, to improve percentage of damage, improves anvil utilization rate, close to " stone forges iron " crushing effect, if
Material abrasivity is stronger, then can step back installation, abrasion is made to decrease.
The flexibility of this i.e. anvil front-rear position adjustment, i.e. the front-rear position of anvil can be adjusted as needed, not be
It is changeless.Front-rear position referred to refers to distance of the anvil from rotor outer circle, and the front-rear position of anvil can be according to not
Scene adjustment together is adjusted accordingly outside, uses for the first time in addition to that can be judged in the design phase before the manufacturing
Afterwards, using effect feeds back to manufacturer, can provide anvil component adjusted again, even if the use site that replacement is different,
Still can neatly it adjust.User can equally obtain most between anvil utilization rate, abrasion cost, percentage of damage, fineness modulus
Good cost performance.
Anvil bear the scope of attack, in principle should in face of cast can broken material supplied materials direction, projectile can broken material supplied materials
Direction, maximum influence factor are the linear velocities of rotor edge, are accurately described, and are at rotor thrower head carbide chip
Linear velocity, be herein can broken material leave the rearmost point of rotor, second is that can the speed that is slided outward from rotor center of broken material
Degree, this constraints are complicated, it is difficult to it is quantitative to calculate, third is that can broken material leave after rotor by gravity, windage and other break
Broken material influences.Comprehensive each influence factor can design anvil angle using rotor edge linear velocity as biggest impact factor with this,
Further according to live use state, make corresponding amendment.
The integral form of anvil can be diversified, and all public publications or the pattern sold in the market can apply to
In this structure, about 20%~70% height of its mid portion is only taken.Normally, anvil is to be fixedly installed to shell in the middle part of host
, it is preferable to use supporting structure, this bracket constitute a circumference substantially on internal or dedicated anvil bracket, whole can hang
Dress is removed.
The installation of anvil component is removed easily, and the installation of anvil is other than the existing way of upper segment description, in order to make to hold high
Anvil utilization rate made of expensive wear-resistant material is high as far as possible, setting mounting structure few as far as possible, so, it is often used the modes such as clamping
Installation, such mounting means, the use environment of host be it is very severe, inside cavity accumulates silt particle, there are also certain water content,
Often that anvil card slot etc. is stuck, rust is dead, makes to clamp and removes difficulty, traditional anvil abrasion is unequal, and abrasion is close in the middle part of anvil
It is just needed replacing when capsule components, still there are more preservation in top and the bottom, on the one hand waste larger, and it is tired on the other hand to also result in dismounting
It is difficult.The mode of whole anvil frame, use when being often used in replacement lumen type, is individually replaced anvil, does not dismount anvil frame usually,
And anvil is removed from anvil frame.In order to overcome this difficulty, also facilitate height, the height and position, anteroposterior position of adjustment anvil
It sets, anvil and backboard, bottom plate is formed into anvil component.This component is hung tag again on cavity backboard, the integral hoisting of anvil component,
It removes very convenient.The more traditional anvil of this anvil is short, and sufficiently, middle section has been ground, and still has backboard, bottom plate that can adhere to wear-resistant one for abrasion
The section time, anvil remainder may grind at this time, completely utilize whole wear-resistant materials, and the backboard of anvil component, bottom
Plate is common iron production, and cost is relatively low, and last remainder is allocated as abandoning processing, little waste.
This anvil component with backboard, bottom plate, the mounting structure of type chamber rearward, even if anvil has all been worn, are carried on the back
Board bottom plate has part wears, without the mounting structure part of wear pattern chamber because the stone lining of lower part by with the abrasion of anvil by
Step extends, and the mounting structure of type chamber is within the angle of repose entity of stone lining, and the backboard of anvil will not all be worn, the peace of type chamber
Assembling structure will not be more worn down to.
Design of the anvil with backboard, keeps the mounting height of anvil adjustable, if the thickness for the bottom plate that adds deduct or
Steel plate combination number of packages, so that it may which the height for increasing or decreasing anvil makes anvil height middle line and dish out can broken material normal state point
Cloth central axes are overlapped, and wear-resistant material is made to use maximization.
The front-rear position of anvil is adjustable, as long as increasing or decreasing the thickness of anvil backboard, can make the front and back of anvil
Position changes, to adapt to different requirements.
The thickness of anvil is adjustable, and anvil back plate design has larger thickness, can be according to requiring to switch to anvil thickness, to having
Scene, the abrasion of anvil is very fast, replacement need to shut down, manual operation, in subsequent accessory, reduce back plate thickness, increase
Anvil thickness can extend anvil using the time, reduce downtime.
The shape of anvil can be modified, Different field, and the nubbin that anvil abrasion is finally retained is different, subsequent
It can be corrected in accessory, make anvil all completing close to synchronous abrasion as far as possible.
The subsequent improvement of anvil can be applicable in, because anvil provides as a whole with backboard, the shape of anvil is clamped
Structure changes, and only changes the structure type of backboard, constant with the mounting structure of type chamber, subsequent to have more excellent anvil to set
Meter, is equally applicable to the host produced before this.
The whole design of lumen type, type chamber can be fixed in host middle housing, non-exchange, and better scheme is, such as
, can be the same with integral replacing with tradition " stone forge iron chamber " with " stone-crash-stone chamber " using whole design, central-axis type iron-stone mixing chamber
Using whole design, in the shortest time, least replacement cost is freely replaced between three kinds of lumen type in the short time.
The great flexibility replaced inside lumen type, although central-axis type iron-stone mixing chamber initial purpose is to improve stronger abrasion
Property can broken material percentage of damage, determine that anvil height takes the height of " stone forges iron " anvil 20%~70%, but scene can fragment
Expect that change of properties may be larger, and host may change use site, being described above certainly can change by more remodeling chamber
Become lumen type, but central-axis type iron-stone mixing chamber itself just has the flexibility of transformation lumen type.As anvil height takes and former " stone forges iron "
The same height of anvil, and take anvil site close to rotor, then " stone forges iron " chamber is converted to, certainly, with original-pack " stone forges iron "
Chamber, which still has, a little to be distinguished, and herein, cannot use " middle part air -return duct " patent.
Anvil component is removed into part, then has the effect similar to CN200520046856.9, but also have biggish difference.
In a circumferential direction, some segmental arcs are iron-stone mixing chamber to central-axis type iron-stone mixing chamber, and it is stone lining chamber that some segmental arcs, which return, in circle
Changing to improve the fineness modulus and content of stone powder of finished product for two kinds of cavity different proportions of circumferential direction, reduces unnecessary abrasion,
The adjustment of this ratio has diversification, completes at the scene completely.And CN200520046856.9 can only be designed before production
The ratio of two kinds of chambers cannot convert at the scene.The anvil component that central-axis type iron-stone mixing chamber removes still may be used at follow-up operation
In.It is high to adjust flexibility, can will appoint easy one or several anvil components dismountings, and arbitrarily combine, formation one iron, one stone, one
Two stone of iron, two Shi Yitie, two Shi Ertie, etc..Such " central-axis type+circumferential direction mixed type chamber " not as CN200520046856.9 that
Sample wear-resistant material still has larger waste, by anvil height, the adjustment of position, the not waste of wear-resistant material herein.Reach and changes
The fineness modulus and content of stone powder of kind finished product, reduce the purpose of unnecessary abrasion, there is very big flexibility, it is very careful to can be carried out
Adjustment.
Some operating conditions, do not need anvil, can broken material finished product job requirements if host runs a period of time in certain building site
Change, or be moved to the operation of other building sites etc., operation purpose be changed to can broken material shaping, it is broken to require, only reduce
It can broken material elongated particles, or it is broken require less, stone-crash-stone can be competent at completely or material source is changed to high abrasion
Material, anvil rapid wear, etc..At this point it is possible to which anvil component is all removed, return " stone-crash-stone type chamber ", uses completely
Stone lining is broken, shaping, not the wear problem of anvil.Even if not changing, wait run a period of time, anvil is all worn, no
New anvil is changed again, then is converted to stone-crash-stone type chamber naturally, and scene, which can freely decide whether to shut down, removes anvil component.
" central-axis type iron-stone mixing chamber " is returned to from " stone-crash-stone type chamber " is changing into, it is only necessary to anvil component is installed,
Install anvil component number of packages number, can be tested at the scene, carry out careful adjustment.It can also be in subsequent anvil group
During part accessory is ordered goods, propose that more suitably height, position, shape etc. require.
Such type chamber requires the radial width of central cavity to have enough rings by the annulus width design of the type chamber of stone-crash-stone
Bandwidth, because of the angle of repose entity of stone lining, ring width is wider, and outermost stone lining height is higher, when the height of outermost stone lining reaches
Arrive or when close to rotor height, at this point, because cast can broken material normal distribution, it is seldom can broken material reach on rotor
The corresponding stone lining position of the height of backplate, the exposure of cavity structure more than this position, by few projectiles can broken material beat
Hit, have very least a portion of reflection can broken material may reach this position, but because quantity is few and granularity is small, stall after shock
Pass through gravity, windage reduction of speed again, will not substantially wear steel construction herein.
If the annulus narrower width of type chamber, the angle of repose entity part of stone lining, the height finally reached is insufficient, does not have
Protect the steel construction of type chamber, cast can broken material it is more can broken material reach the steel construction of type chamber, if do not had
The top of additional protection, the steel construction of type chamber will be worn, as described in CN201220636591.8, type chamber it is upper
Portion is easier to be worn, and needs additional protection.
Although central-axis type iron-stone mixing chamber initial purpose be improve stronger abrasion can broken material percentage of damage, for
In the material of medium and following abrasion, this central-axis type iron-stone mixing chamber can be equally used, it may be assumed that use " stone forge iron chamber " in tradition
Operating condition, use " central-axis type iron-stone mixing chamber " can be changed to, because dishing out being crushed of normal distribution axis far from material
Material be it is seldom, this is changed to the percentage of damage of stone-crash-stone far from the percentage of damage that part is forged iron from stone, for whole percentage of damage shadow
Sound is smaller, and 70%~30% anvil abrasion can be saved in cost.Moreover, many low corrosion materials forge iron with stone
Chamber, reduction ratio is very high, but the yield of mountain flour but also far beyond demand, cause very big waste, be partially changed to stone-crash-stone effect, stone
Powder content is declined, and is also reduced waste, is reduced cost.
For stronger abrasion can broken material, although can broken material abrasion improve, central-axis type iron-stone mixing chamber
It improves anvil abrasion cost and eliminates the part of waste, whole unit product steel per ton because the utilization rate of anvil improves
Abrasion loss does not improve, though increase, percentage of damage improves more, and overall efficiency improves, and makes the energy of whole system
Power preferably plays, and benefit is higher.Moreover, such type chamber have diversified adjustment modes, user can anvil utilization rate,
Abrasion cost, percentage of damage obtain optimum efficiency between fineness modulus.
Middle department's anvil loss of weight, in host in the market, part middle part is not opened the door, this host uses central-axis type iron-stone
Mixing chamber is complete 360 degree of circumference to.And having part host is opened the door at middle part, facilitates observation, detection, maintenance, replacement is matched
Part etc., such host are to interrupt on the corresponding radian of middle department, and traditionally, the forge iron anvil of middle sector location of chamber of stone is
It hangs in department, because of arm length, weight weight, mobile, rotation more difficulty, it is also possible to lead to the deformation etc. of door-plate, this axis
The theory of formula iron-stone mixing chamber, the anvil in Shi Zhong department are reduced to 30% or so of original weight, make this problem have compared with
Good settling mode.There are also one mode, be anvil is placed in middle part bottom plate on, remove behind the door, then remove anvil, originally because
Anvil weight weight, volume are big, remove mainly manually, and narrow space, operation is very inconvenient, similarly, after reducing weight, in
The loss of weight anvil movement of department will become a not difficult thing.
The mounting means of anvil, when anvil is located at rearward position, is hanging down because the front-rear position variation of anvil is larger
Histogram is interfered with the annular upper cover plate above L shape upwards, if mode manually is first put into close to the position of rotor, then manually
Mobile, this mode is feasible, but anvil component is heavier, and movement is more difficult, cover board can be made to the mode of being actively coupled, and be divided into
Several piece.During installation, anvil component is first installed, it is rear that mixing chamber annular upper cover plate is installed, when disassembly, first tear annular upper cover plate open, after
Tear anvil component open.
The beneficial effects of the present invention are: one, use in tradition the operating condition of stone-crash-stone chamber, it is mixed that central-axis type iron-stone can be changed to
Close chamber, improve crushing efficiency, improvement can broken material fineness mould degree, reduce the steel abrasion loss of finished product per ton, and improve scene
Adjustment flexibility, reach the crushing effect close to " stone forge iron type chamber ", two, entire crushing production line can be made, play other
Whole abilities of machinery equipment improve final products yield, improve the output proportion of each final products, are allowed to more rationally.Three, it passes
System is forged iron the operating condition of chamber using stone, is also replaced by central-axis type iron-stone mixing chamber, with similar crushing efficiency, is reduced finished product per ton
Steel abrasion loss reduces content of stone powder, and improvement can broken material fineness mould degree.Four, scene adjustment position height, front-rear position are provided
Flexibility and subsequent adjustment anvil height, the flexibility of anvil site height, thickness, shape, front-rear position, five, can basis
Different field, different operating condition flexible transformations between various type chambers.Six, middle department's anvil weight saving, it is easy to operate.
Specific embodiment
In order to improve the crushing efficiency of vertical shaft impact crusher, improvement can broken material fineness mould degree, reduce mountain flour and contain
