Ceramic raw material rough crushing device

Abstract

The invention relates to the field of ceramic sanitary wares, and in particular, discloses a ceramic raw material rough crushing device. The ceramic raw material rough crushing device comprises a shell, first springs, second springs, a polishing plate, a grinding head and electromagnets; an annular groove for mounting the polishing plate is formed in the inner wall of the lower end of the shell; the radian of the polishing plate is the same with the radian of the inner wall of the shell; multiple first springs are arranged between the polishing plate and the inner wall of the annular groove; one ends of the first springs are welded with the inner wall of the annular groove, and the other ends of the first springs are welded with one side of the polishing plate; multiple grinding teeth, opposite to the side surfaces of the grinding head, are arranged on the other side of the polishing plate; multiple mounting grooves are formed in the side surfaces of the grinding head; the second springs and the electromagnets capable of attracting the polishing plate are arranged in the mounting grooves; one ends of the second springs are welded with the inner walls of the mounting grooves; and the other ends of the second springs are welded with the electromagnets. The ceramic raw material rough crushing device can clean powder raw materials attached on the grinding teeth.

Description

technical field [0001] The invention belongs to the field of ceramic sanitary ware, and in particular relates to a coarse crushing device for ceramic raw materials. Background technique [0002] The raw materials for making ceramic sanitary ware are all kinds of ores. Most of the ores are relatively hard and in the form of solid blocks. It is necessary to use a commonly used pulverizer to crush the solid raw materials. According to different crushing stages, different crushing devices will be selected for crushing processing, such as coarse crushers, pulverizers, and ultrafine pulverizers. Generally, coarse crushers are used for preliminary processing of raw materials. When using coarse crushers, coarse crushing The crushing degree of raw materials in the process is uneven, some raw materials after grinding are powdery, and some raw materials are granular or block. [0003] Blocky or granular raw materials are easy to fall out of the coarse crusher, but powdery raw material...

AI Technical Summary

Problems solved by technology

[0003] Blocky or granular raw materials are easy to fall out of the coarse crusher, but powdery raw materials are easy to adhere to the grinding teeth in the coarse crusher. Long-term adhesion will cause the grinding teeth to be covered by powdery raw materials. This will lead to the failure of the grinding of the raw materials; at the same time, it is easy to get the blocky raw materials stuck in the coarse crusher, which will greatly reduce the coarse crushing efficiency of the raw materials.
