Raw material crushing system with back blowing function

Abstract

The invention discloses a raw material grinding system with a blowback function. The raw material grinding system is characterized in that both a grinding chamber and a motor are fixedly arranged on a supporting box; a hopper is mounted on the grinding chamber and is communicated with the grinding chamber; the grinding chamber is provided with a cavity in a cylindrical structure; the motor is connected with a rotary shaft; one end of the rotary shaft extends into the cavity; the rotary shaft is sleeved with a cutting rotary wheel; the cutting rotary wheel is arranged in the cavity; a pipeline is arranged on the supporting box; one end of the pipeline is connected with an air pump; the air pump is arranged outside the supporting box; the pipeline extends into the supporting box, is communicated with the grinding chamber and is higher than the bottom end surface of the cavity; an air outlet is formed in the top end of the grinding chamber and is communicated with the cavity; a dust baffle sieve is arranged in the air outlet, is fixed on the grinding chamber and completely covers the air outlet. According to the system, the pipeline is connected with the air pump, so that raw materials are blown up during grinding, the raw material deposition is avoided, and ground particles are uniform.

Description

technical field [0001] The invention relates to a system, in particular to a raw material crushing system provided with a blowback function, and belongs to the field of biomechanics. Background technique [0002] Crushing is the application of external force to solid materials to split them into smaller particles, a unit operation belonging to powder engineering. The solid raw materials and coal used in chemical production often need to be crushed to a certain particle size before they can be used. For example, in most chemical reactions involving solid particles, reducing the particle size can increase the interphase contact surface and increase the reaction rate. In the leaching operation, reducing the particle size can not only increase the interphase contact surface, but also shorten the diffusion distance of the substance in the particle and increase the leaching rate. In the production process of ceramics, cement, pigments, catalysts, etc., in order to obtain a unifo...

Problems solved by technology

[0004] The purpose of the present invention is to overcome the phenomenon that some materials are prone to deposit during the crushing of the above-mentioned existing crushing equipment, resulting in the problem that the crushed particles are uneven, and a raw material crushing system with a back blowing function is designed. The pipeline is connected to the air pump so that the raw materials are blown up during crushing, avoiding the deposition of raw materials, and making the crushed particles uniform, which solves the problem that some materials are prone to deposit during crushing in existing crushing equipment, resulting in uneven crushed particles question
