Abstract

The invention discloses a mouse cage type crusher, and belongs to the field of mechanical equipment. The existing mouse cage type crusher can be used for crushing a material in a manner that a fixed collision roller is utilized to collide the material at a suspended state, has the advantages of fine cracking particle size, large ratio of size reduction, and the like, is widely applied to industries of mines, building materials, chemical industry, feeds, food, medicines, plastic and the like, and is high in production efficiency, long in service life, low in feed back amount, little in maintenance, and safe and reliable to run; and however, the existing mouse cage type crusher also has certain disadvantages that the working speed is high, the work noise is large, the collision roller is easy to wear and the material is easily over-crushed; aiming at the disadvantages in the prior art, the invention provides the mouse cage type crusher which mainly comprises a large rotor belt wheel, a shaft structure, a machine enclosure, a large rotor, a small rotor, a feed chute, a small rotor belt wheel and a base; the mouse cage type crusher solves the problems of the mouse cage type crusher in the prior art that the working speed is high, the work noise is large, the collision roller is easy to wear and the material is easily over-crushed.

Description

A kind of cage mill

Technical field

The invention belongs to the plant equipment field, relate in particular to a kind of cage mill.

Background technology

Cage mill is to utilize the fixing material impacting that hits roller and suspended state that raw material is pulverized, have the advantages such as particle size after cracking is thin, the ratio of reduction is large, extensive use in the industries such as mine, building materials, chemical industry, feed, food, medicine, plastics mainly is applicable to the pulverizing to some soft materials; In the brickmaking industry, cage mill is used for the raw materials such as clay, material spoil, slag are carried out in small, broken bits and blending, and its production efficiency is high, the life-span is long, the feed back amount is low, a little repair, running are safe and reliable; But also there is certain shortcoming in cage mill, mainly is that operating rate is high, and work noise is large, hits roller and weares and teares easily, and pulverizing appearred in material easily.

Summary of the invention

The purpose of this invention is to provide a kind of cage mill, solved cage mill operating rate height in the prior art, work noise is large, hits roller and weares and teares easily, and the problem of pulverizing appearred in material easily.

In order to achieve the above object, the present invention by the following technical solutions: a kind of cage mill mainly is comprised of greater trochanter belt pulley, axle construction, casing, greater trochanter, lesser trochanter, feed well, lesser trochanter belt pulley and support.

A kind of cage mill, greater trochanter, lesser trochanter are under the driving of each automatic drive device during work, High Rotation Speed in the opposite direction, material to be pulverized continuously enters in the cage from the feed well of casing top, the roller that hits when falling and on the rotor of High Rotation Speed bumps against, lump material is broken up pulverizing, and the material through pulverizing enters conveyer belt input mixing cylinder from hopper, finishes broken process.

A kind of cage mill, the linear velocity use value of rotor is taken as v=25 ~ 35m/s, the best v=30m/s that uses; Screw-thread steel with diameter 10 ~ 15mm is made 2 L shaped, and symmetry is fixed on the large cage wheel, takes turns a side at little cage and fixes one section reinforcing bar, adds reinforcing bar and scrapes material device as one, and 1 week of revolution can scrape the wide space of 10 ~ 15mm; Adopt variable-frequency control technique to adjust rotating speed, the reparation of adopting the technique for overlaying manufacturing to hit roller and hit roller, the employing wet pulverizing reduces noise and reduced degree of grinding, adopts the reduction vibration of sound insulation vibration isolation technique and noise.

The bright beneficial effect of this law is: guarantee no backup between large and small rotor, the output of the material of guaranteeing to be broken is smooth and easy; When motor reached rated current equally, pulverizer production capacity was than originally greatly improving; Reduce degree of grinding, and made machine be in optimum Working, can satisfy different granularity requirements simultaneously; Work noise is little, and it is good to hit the roller wearability.

Description of drawings

Fig. 1 is a kind of cage mill structural representation.

Among the figure: 1, greater trochanter belt pulley, 2, axle construction, 3, casing, 4, greater trochanter, 5, lesser trochanter, 6, feed well, 7, the lesser trochanter belt pulley, 8, support.

The specific embodiment

A kind of cage mill as shown in fig. 1, mainly is comprised of greater trochanter belt pulley 1, axle construction 2, casing 3, greater trochanter 4, lesser trochanter 5, feed well 6, lesser trochanter belt pulley 7 and support 8.

A kind of cage mill, as shown in fig. 1, greater trochanter 4, lesser trochanter 5 are under the driving of each automatic drive device during work, High Rotation Speed in the opposite direction, material to be pulverized continuously enters in the cage from the feed well 6 of casing 3 tops, and the roller that hits when falling and on the rotor of High Rotation Speed bumps against, and lump material is broken up pulverizing, material through pulverizing enters conveyer belt input mixing cylinder from hopper, finishes broken process.

A kind of cage mill, the linear velocity use value of rotor is taken as v=25 ~ 35m/s, and the best is used v=30m/s, has guaranteed no backup between greater trochanter 4, the lesser trochanter 5, lesser trochanter 5 linear velocities need be slightly larger than the linear velocity of greater trochanter 4, and the output of the material of having guaranteed to be broken is smooth and easy; Screw-thread steel with diameter 10 ~ 15mm is made 2 L shaped, symmetry is fixed on the large cage wheel, take turns a side at little cage and fix one section reinforcing bar, add reinforcing bar and scrape material device as one, 1 week of revolution can scrape the wide space of 10 ~ 15mm, guaranteed that mouse cage only has the material between reinforcing bar and casing to contact in the running, contact area is very little, and the large tracts of land of whole rotor not with the material extrusion friction, thereby resistance is reduced greatly, and when entering inventory on an equal basis, current of electric reduces greatly, when motor reached rated current equally, pulverizer production capacity was than originally greatly improving; Adopt variable-frequency control technique to adjust rotating speed, can reduce degree of grinding, make machine be in optimum Working, can satisfy different granularity requirements simultaneously; Adopt technique for overlaying can obtain the effect of resistance to wearing preferably for the manufacture of hitting roller with the reparation of hitting roller, can greatly prolong the service life of hitting roller as using the tungsten electrode built-up welding; The employing wet pulverizing can obviously reduce noise and reduce degree of grinding; Improve manufacturing technology level, reduce unbalance mass,, adopt the sound insulation vibration isolation technique can reduce vibration and noise.
