Hammer slice type pulverizer

Abstract

The invention discloses a hammer slice type pulverizer. The hammer slice type pulverizer comprises a feed device, a rotor, hammer slices, a screen plate, a discharge device and a motor. The hammer slices are connected to the rotor. The rotor is connected with the motor through a spindle. The hammer slice type pulverizer further comprises brush slices. Each brush slice is a cuboid tightly formed by a plurality of brush strips. The tail end of each brush slices is close to the screen plate. By installing the brush slices in the pulverizer, particles attached to a screen slice or screen holes can be effectively scraped off, and the screen slice is prevented from being blocked; it is beneficial for the pulverized particles to be discharged out of the screen plate normally, and the production efficiency is improved effectively; meanwhile, after the pulverizing process is completed, the screen plate can be cleaned through the scraping effect of the brush slices, the tedious procedures that the screen plate is dismantled manually for overhauling and cleaning the screen plate are reduced, and the time and effort are saved.

Description

technical field [0001] The invention relates to a pulverizer, in particular to a hammer pulverizer. Background technique [0002] At present, hammer mills are widely used in feed, grain, food, medicine, chemical and other industries. [0003] After the material enters the crushing chamber from the feeding device, it is crushed by the impact of the high-speed rotating hammer, and hits the tooth plate, sieve plate or screen mesh fixed on the machine body at a high speed to be further crushed, and then bounces back to be crushed again. When the hammer strikes, the material is also subject to friction and shearing, and the cycle goes on like this. Finally, when crushed to a certain extent, the particles with a particle size smaller than the sieve mesh pass through the sieve under the action of centrifugal force and are discharged through the discharge device; the particles with a particle size larger than the sieve mesh continue to be crushed in the crushing chamber until they ...

AI Technical Summary

Problems solved by technology

In the process of discharging small material particles through the sieve plate, since the specific surface area per unit mass of the particles increases with the decrease of the particle size, they are easy to attach and agglomerate, resulting in the blockage of the sieve plate holes, and the crushed granular products cannot be discharged normally, affecting production. efficiency, and the cleaning of the sieve plate is also time-consuming and labor-intensive, which seriously restricts the normal operation and use of the pulverizer
