Automatic feeding type crushing device for high-strength structural ceramic particles

Abstract

The invention discloses an automatic feeding type crushing device for high-strength structural ceramic particles, relates to the technical field of ceramic preparation, and solves the problems that the existing crushing device is poor in crushing effect, relatively centralized in feeding and easy to accumulate materials because the ceramic particles are crushed through only one group of rotary cutters, and the existing crushing device cannot continuously work and is relatively low in working efficiency. The automatic feeding type crushing device comprises an outer shell; a group of driving motors are fixedly connected to the right side of the outer shell; a group of upper crushing mechanisms are rotatably connected to the inner part of the outer shell; and a group of feeding adjusting mechanisms are arranged at the lower part of a feeding mechanism. The device is capable of adjusting the feeding speed, the materials are sprinkled in a crushing cavity in a uniform and disperse mode, andthe materials are crushed through an upper crushing blade and a lower crushing blade which rotate reversely, such that the crushing speed and the crushing effect are improved, meanwhile, the materials are screened through a screening net, continuous working can be carried out, the crushing effect is good, and the work efficiency is high.

Description

technical field [0001] The invention relates to the technical field of ceramic preparation, in particular to an automatic feeding crushing device for high-strength structural ceramic particles. Background technique [0002] In the preparation of high-strength ceramic particles, the ceramic particles need to be crushed. The indentation toughness of oxide high-strength ceramic particles is KIc>3, and the hardness is>HV301600. The diameter of oxide high-strength ceramic particles obtained by traditional preparation methods is generally 10 -15mm, in order to improve the strength of ceramics, it needs to be crushed to equiaxed particles of 1-3mm. In the crushing of ceramic particles, a crushing device is generally used to crush ceramic particles. [0003] For example, application number: CN201720585791.8 This utility model oxide high-strength ceramic particle crushing device includes a crushing tank body, a crushing drive device arranged at the lower end of the crushing tan...

AI Technical Summary

Problems solved by technology

[0005] The object of the present invention is to provide a kind of automatic feeding crushing device of high-strength structural ceramic particles, to solve the problem that the existing crushing device proposed in the above background technology only crushes ceramic particles through a group of rotating cutters, and the crushing effect is relatively poor. At the same time, when the existing crushing device is feeding, due to the relatively concentrated feeding, it is prone to material accumulation, resulting in uneven crushing. At the same time, the existing crushing device cannot work continuously, and the working efficiency is relatively low.
