Description

A kind of numerical control multi-stage crushing device

Technical field

The utility model is related to disintegrating apparatus, simple more particularly, to a kind of compact conformation, the high number of a crush efficiency Control multi-stage crushing device.

Background technology

Pulverizer is mainly used in the middle finess disintegrating operation of every profession and trade, and it is by granular materiel machining to needs that it, which is acted on, The middle fineness of diameter（60-100 mesh）Powder, to carry out subsequent treatment or to be used as raw material.It is rotated using high speed The synthesis external force that hammer leaf is produced is processed to producing powder to fragility material.At present, the problem of pulverizer is primarily present one be： One time degradation rate is not also high, and secondly also having is：The part service life of some in disintegrating apparatus is not long；It is again：Powder in crushing process Dustiness dye is larger.For the more phenomenon of first problem generality, mostly take and put forward high-revolving method to solve, but improve Rotating speed will increase the structural rigidity of equipment, increase the structural complexity of equipment, so that the manufacturing cost of equipment can be improved；Or adopt Take the method for separating twice to solve, can so increase the time cost of crushing, reduce pulverizing processing efficiency.

Utility model content

For it is above-mentioned degradation rate is not high in the prior art the problem of, the utility model provide a kind of compact conformation it is simple, Only once degradation rate is not high, and service life is long, the few numerical control multi-stage crushing device of dust pollution.

The technical problems to be solved in the utility model to be adopted the technical scheme that：The numerical control multi-stage crushing device bag One-level reducing mechanism, second patent flour crushing device and digital control implement are included, the one-level reducing mechanism includes housing, rotating shaft and liner plate, housing The hammer that multilayer and the distribution that is stepped are movably set with support frame, support frame as described above is provided with rotating shaft between upper and lower ends Piece, every layer of hammer leaf is arranged at intervals, and loading hopper is provided with housing upper end, and liner plate is arranged on the madial wall of housing and divided with hammer leaf Cloth is corresponding, and liner plate between layers is stepped distribution, and every layer of hammer leaf is identical with the distance between liner plate, in the liner plate Interleaved is provided with raised line on surface, and crushed material can be transported to the conveying plate of feed opening by being provided with rotating shaft lower end, described Vibrating screen classifier is provided with below feed opening, the second patent flour crushing device is arranged on below the middle hopper of vibrating screen classifier, it Including casing and be arranged in casing and can rotate against turn pressure roller, it is described turn to be arranged at intervals with pressure roller outer surface it is wear-resisting Block.

Lump material is first added and crushed in one-level reducing mechanism by the utility model, because hammer leaf and liner plate have multilayer And be stepped, material will not fall directly into housing bottom when first layer is not crushed, and be into second layer hammer leaf and lining Between plate, even drop between third layer hammer leaf and liner plate, be so greatly improved crush efficiency, crush efficiency is than existing Pulverizer improves more than 10%, and the material crushed by one-level is crushed by vibrosieve into second patent flour crushing device, and two Level crush effect be the crushing material for crushing one-level to 60-120 mesh, and ensure the broken rear degradation rate of second patent flour reach 95% with On.The utility model compact conformation, crush efficiency is high, good crushing effect, and reducing mechanism durability is strong, and service life is long, extensively Used suitable for industries such as metallurgy, mine, building, chemical industry.
