Coal pulp pulverizer

Abstract

The invention provides a coal pulp pulverizer. The coal pulp pulverizer comprises a feeding port (31), a feeding part, a pulverizing part and a discharging port (36) which are connected in sequence; the pulverizing part comprises a cylinder (1) and a rotor (2); the cylinder (1) is provided with a screen mesh (5) area; the inner wall of the cylinder (1) is provided with a plurality of convex fixedteeth (7) which are arranged in a plurality of rows along the inner wall of the cylinder (1); each row comprises a plurality of the convex fixed teeth (7) which are arranged in the vertical direction;a gap section (8) is arranged between two adjacent rows of the convex fixed teeth (7) to serve as the space for a material to fall down; a plurality of convex rotating teeth (9) are arranged on the periphery of the rotor (2); at least two rows of the convex rotating teeth (9) are arranged along the periphery of the rotor (2); each row comprises a plurality of the convex rotating teeth (9) which are arranged in the vertical direction; a gap groove (23) is formed between two adjacent rows of the convex rotating teeth (9) to serve as the space for the material to fall down; space required for atarget particle size of the material is reserved between the convex rotating teeth (9) and the convex fixed teeth (7) which are engaged with each other; the pulverized material particles are uniform;and the pulverizing efficiency is high.

Description

Technical field [0001] The invention belongs to the technical field of crusher manufacturing, and specifically relates to a coal slurry crusher. Background technique [0002] The crusher is a machine that crushes large-size solid materials to the required size. Generally, solid-liquid mixing during crushing is widely used in the fields of chemical industry, metallurgy, plastics, food, pharmaceuticals, and construction. The coarse crusher is mainly used for the pretreatment of crushing in various industries, and its function is mainly to process materials with larger diameters into granular materials with smaller diameters. [0003] my country is a large coal-producing and coal chemical industry. When raw coal is used as a coal chemical raw material, it must first be crushed and pretreated. When crushing, raw coal needs to be mixed with water, which is called coal slurry, also called coal water slurry. The ideal state is to be crushed into uniform coal particles with an outer diam...

Problems solved by technology

Therefore, the pulverizers in the prior art always have the following defects: one is that the pulverized materials are of different sizes, very uneven, and the content of fine powder is higher; the other is that the equipment occupies a large area and the pulverization efficiency is low
