A production process of high-strength green silicon carbide micropowder and its special grinding machine

Abstract

The invention discloses a production process for high-strength green silicon carbide micropowder and a special grinder for the high-strength green silicon carbide micropowder. The special grinder comprises a horizontal mill body (1), a slurry circulation pump (2), an iron remover (4) and a settling tank (5), wherein the discharge hole of the horizontal mill body (1) is communicated with the feeding hole of the settling tank (5) by virtue of a slurry conveying pipeline A (3), the iron remover (4) is arranged between the slurry conveying pipeline A (3) and the feeding hole of the settling tank (5), the discharge hole of the settling tank (5) is communicated with a feeding hole of the horizontal mill body (1) by virtue of a slurry conveying pipeline B (3'), and a slurry flow control valve (8) is arranged on the slurry conveying pipeline B (3'). According to the production process for high-strength green silicon carbide micropowder and the special grinder disclosed by the invention, the problem of the traditional green silicon carbide micropowder that the strength and the cutting force are influenced as the particle sizes of the traditional green silicon carbide micropowder are different is solved, and the problem of the traditional grinder that in the grinding process, powders in different particle sizes are mixed and ground to cause excessive grinding is also solved.

Description

technical field [0001] The invention relates to the technical field of micropowder processing equipment, in particular to a production process of high-strength green silicon carbide micropowder and a special grinder thereof. Background technique [0002] At present, the production technology of green silicon carbide micropowder in my country is at a low-level stage, and high-grade products cannot be produced. The green silicon carbide micropowder produced in China today is basically low-quality ordinary micropowder. Its characteristic is that the product with strong grinding force is not wear-resistant, and the product with wear-resistant force is not strong in grinding force. The reason is that in the products produced by the existing technology, some particles have low hardness, which are easily broken during use and lose the proper grinding ability. The existing green silicon carbide micropowder mixture includes a mixed powder with a particle size ranging from 10 microns...

AI Technical Summary

Problems solved by technology

[0003] The technical problem to be solved by the present invention is to provide a production process of high-strength green silicon carbide micropowder and its special grinding machine. problem, and effectively solve the problem of over-grinding caused by mixing powders with different particle sizes during the grinding process of traditional grinders

[0004] The invention not only effectively solves the problems of wear resistance and cutting force of traditional green silicon carbide micropowder, but also effectively solves the problem that particles with qualified particle diameters are no longer ground during the grinding process of traditional grinding machines, thereby improving the yield of products and the like.
