Abstract

The utility model discloses a crusher that crushes materials by the combined activities of hammers and disk elements. The centrifugal hammer type crusher mainly comprises a shell (10), wherein, a feeding hole (2) and a discharge hole (15) are arranged at the upper and the lower parts of the shell (10), and a vertical shaft (12) is installed at the internal center of the shell (10). The utility model is characterized in that centrifugal disks (5) and hammer rods (8) are installed from top to bottom on the vertical shaft (12). The centrifugal hammer type crusher integrates the advantages of centrifugal crushing operation and hammer crushing operation and is suitable for crushing brittle materials with medium hardness.

Description

Centrifugal hammer type crusher

The utility model relates to a kind of crushing mechanism, is a kind of application hammer and the disc elements teamwork equipment with the material fragmentation specifically, and it is suitable for the fragmentation of medium hardness brittle material.

In existing crushing mechanism equipment, mainly be impact crusher, as jaw formula, hammer, impact breaker, they mainly are that dependence jaw or hammer body impose shock loading with the material fragmentation to material, usually the raw meal particle size size that is broken is uneven, can't satisfy the demand, and work package is fragile; There is centrifugal crusher to come out in recent years again, it mainly is to depend on the centrifugal pan of rotation at a high speed, material is subjected to centrifugal action and is subjected to liner plate counterattack and material broken from hitting mutually after by high-speed projectile when centrifugal pan rotates at a high speed, high with regard to the inevitable requirement centrifugal rotational speed like this, the bearing part of bolster spare influences the life-span because of heating.

The purpose of this utility model is to provide a kind of disintegrating machine that centrifugal fragmentation and hammering are broken for one that collects, and still can obtain satisfactory raw meal particle size when being intended to reduce rotary speed, and can prolong the service life of work package.

To achieve these goals, the technical solution adopted in the utility model is: the charging aperture that drops into for material is arranged at crusher shell top, the discharging opening of discharges material is arranged at the bottom, one vertical shaft is arranged in the housing between two parties, this vertical shaft can rotate around its supporting-point, and its special feature is: described vertical shaft is equipped with centrifugal pan and hammer rod from top to bottom.Material is by on the centrifugal pan that drops down onto rotation at a high speed in the charging aperture input machine, under centrifugal action, material is broken up to the casing inner wall broken by impelling, fall to that rotary hammer rod place is hit once more and broken through this broken material, thereby obtain the material that granularity meets the requirements.

The utility model has compared with prior art overcome the pattern of single centrifugal fragmentation in the prior art or single impact grinding, and both organically has been combined as a whole, thereby has guaranteed still can obtain conforming with under the situation that reduces rotating speed the material of granularity requirements; The reduction of rotating speed again and then reduce the block bearing heating makes increase its service life; Shattering process impacts by centrifugal and hammer rod and finishes, so the work package damaged condition has also obtained containment; In addition, centrifugal pan of the present utility model and the excellent both of hammer are installed on the vertical shaft, thereby have obviously dwindled the volume of equipment.

Fig. 1 is a structural representation of the present utility model.

Below in conjunction with drawings and Examples utility model is done further explanation.

Embodiment

Among Fig. 1, housing (10) is a round barrel shape, its loam cake is connected with charging aperture (2), bottom end cover leaves discharge gate (15), vertical shaft (12) is supported in, between the bottom end cover, promptly on the bearing and housing (10) of the two ends suit of vertical shaft (12), the bearing block of lower cover center matches, the upper end of vertical shaft (12) extends housing (10) outside, be connected with belt pulley (1) on it, centrifugal pan (5) is installed on the vertical shaft (12), be positioned at the first broken chamber (6) shown in the top of inner chamber of housing (10), the card of centrifugal pan (5) can be accepted the material that is fallen by charging aperture (2) input, on the centrifugal pan (5) radially radiation-like be distributed with dividing plate (4), dividing plate (4) is provided with 3～6 usually and gets final product.The material that drops down onto on the centrifugal pan (5) is thrown on the liner plate (11) by centrifugal action, material is along himself crack or internal force weakness and fragmentation, and forming new crack and internal force weakness, these materials are collided and fragmentation by the material in the back impelling again when rebounding from liner plate (11).

Three layers of hammer rod (8) are installed on the axostylus axostyle of the vertical shaft (12) below centrifugal pan (5), promptly three layers of hammer rod (8) be mounted respectively in diagram in the broken chamber (7), chamber in small, broken bits (9), every layer of hammer rod (8) installed 3～4 and got final product, two support plates (14) on the vertical shaft (12) and pin are outstanding to be propped up by being sleeved on for it, tup one end is unsettled, when its with vertical shaft (12) when together rotating, hammer rod (8) shows parallel cross-like form along the radial distribution of housing (10) between the barred body of upper and lower layer hammer rod (8).Centrifugal pan (5) and support plate (14) are separated the location by vertical shaft (12) Upper shaft sleeve (13).The breaked material in first broken chamber (6) fall enter in the hammer rod (8) that is being rotated of broken chamber (7) repeatedly hit further broken, it drops down onto and continues to be subjected to hammer rod (8) to hit fragmentation in the chamber in small, broken bits (9), raw meal particle size shows the powder shape as a result, and it is discharged from the discharging opening (15) of bottom.

As seen from Figure 1; above-mentioned just, in, in chamber in small, broken bits (6), (7), (9); be separately installed with liner plate (11) on housing (10) inwall; they are corresponding with centrifugal pan (5) and hammer rod (8) respectively; liner plate (11) can be protected housing (10) on the one hand, on the other hand with the material impact crushing.Liner plate (11) bottom shows ramped shaped, and it points to a side at hammer rod (8) place, and material can drop down onto on the hammer rod (8) along this slope and hit by it.

Avoiding dust for the bearing on vertical shaft (12) top enters and weares and teares, one ash discharge blade (3) is installed between the upper wall in centrifugal pan (5) and housing (10), promptly when vertical shaft (12) rotates, ash discharge blade (3) bearing on it that dust blown off thereupon rotating.

In order to satisfy the granularity requirements of different material, according to the fragility of material, can suitably increase or reduce the number of hammer rod (8), and the rotating speed of vertical shaft (12).
