Hammer piece type wear-resisting grinder

Abstract

The invention relates to a hammer-type wear-resistant pulverizer in the field of material pulverization, which includes a pulverizer body, which is arranged in a rectangular shape, a material inlet is provided above the pulverizer body, and a discharge port is provided below the pulverizer body , the interior of the pulverizer body is provided with a main shaft, and the hammer is arranged on the main shaft; the inside of the pulverizer body is equipped with a sieve in cooperation with the hammer on the main shaft, and the sieve is fixed on the sieve fixing device, and the sieve fixing device is self-feeding One end of the feed port continues to the front end of the pulverizer body. The fixing device is U-shaped. The fixing device includes several sets of fixing plates. The fixing plates are connected in series through connecting plates. There is a gap between two adjacent fixing plates. The fixing device set by U is set at the rear end of the feed inlet, and the fixing device is set at a distance from the hammer on the main shaft; the invention can quickly crush the material, and the improved fixing device can improve the crushing efficiency and save energy. consumption.

Description

technical field [0001] The invention relates to a hammer-type wear-resistant pulverizer in the field of material pulverization. Background technique [0002] Material crushing is to apply external force to solid materials to split them into smaller particles, a unit operation belonging to powder engineering; solid raw materials and coal used in chemical production often need to be crushed to a certain particle size before use; for example, In most chemical reaction processes involving solid particles, reducing the particle size can increase the interphase contact surface and increase the reaction rate. In leaching operations, reducing the particle size can increase the interphase contact surface. It can also shorten the diffusion distance of substances in the particles and increase the leaching rate. In the production process of ceramics, cement, pigments, catalysts, etc., in order to obtain a uniform solid mixture, various raw materials are first ground into fine powder; s...

Problems solved by technology

In the production process of ceramics, cement, pigments, catalysts, etc., in order to obtain a uniform solid mixture, various raw materials are first ground into fine powder; some chemical products must be crushed to a certain particle size in order to meet the needs of users. It has a wide range of uses in production; however, due to structural problems, the traditional crushing method wears a lot on the hammer and its fixing device when it works
