Hammer piece type wear-resisting grinder

Abstract

The invention relates to a hammer piece type wear-resisting grinder belonging to the field of material grinding. The hammer piece type wear-resisting grinder comprises a grinder body, wherein the grinder body is in a rectangular shape; a feed inlet is formed on the upper part of the grinder body; a discharge hole is formed at the lower part of the grinder body; a main shaft is arranged in the grinder body in a penetrating way; a hammer piece is arranged on the main shaft in a matching way; a screen piece matched with the hammer piece on the main shaft is arranged in the grinder body, and is fixed onto a screen piece fixing device; the screen piece fixing device extends to the front end of the grinder body from one end of the feed inlet, and is in a U shape; the fixing device comprises a plurality of groups of fixing plates; the fixing plates are connected in series through a connecting plate; a gap is formed between every two adjacent fixing plates; the U-shaped fixing device is arranged at the rear end of the feed inlet; and the fixing device and the hammer piece on the main shaft are arranged at a certain distance. The hammer piece type wear-resisting grinder provided by the invention can grind materials quickly, and through the improved fixing device, the grinding efficiency can be improved, and the energy consumption is saved.

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
