Silicon micro-powder crushing and grinding screening machine

Abstract

The invention discloses a silicon micro-powder crushing and grinding screening machine, and relates to the technical field of silicon micro-powder. The silicon micro-powder crushing and grinding screening machine comprises a machine box. One side of the inner wall of the machine box is fixedly connected with a switch motor through a motor frame. The switch motor is rotationally connected with a first belt pulley through an output shaft. The first belt pulley is rotationally connected with a second belt pulley through a belt. The outer side of the second belt pulley is rotationally connected with a control rotating disc. The top of the inner wall of the machine box is rotationally connected with a pulley through a pulley frame. A steel cable is connected to the position between the controlrotating disc and the pulley. A movable sleeve ring frame is fixedly connected to the position, located on the right side of the pulley, of the top of the inner wall of the machine box. According to the silicon micro-powder crushing and grinding screening machine, the problems that the silicon micro-powder crushing and grinding working efficiency is low, and large impurities after crushing is conducted cannot be removed are solved, the crushing process can also be smoother without using a tool with precision, the working efficiency is improved, a screening net can be dismantled and replaced automatically, and the situation that the screening efficiency is reduced due to plugging of screening holes cannot occur.

Description

technical field [0001] The invention relates to the technical field of microsilica powder, in particular to a pulverizing, grinding and screening machine for microsilica powder. Background technique [0002] At present, in the existing technology, the professional is dedicated to the production and processing of ultrafine powder with high hardness of silicon carbide. Usually, a conventional grinding machine is used. Due to some shortcomings in structural design and materials used, grinding out Silicon carbide is difficult to meet the requirements for use. During the processing of silicon dioxide raw materials, they must first be ground by a dry ball mill before continuing to the subsequent process. However, the existing silicon dioxide raw materials contain many fine impurities such as soil and sand, which easily affect the purity of the silicon dioxide powder. However, the existing continuous dry ball mill does not have a screening device after pulverization, so larger imp...
