Vertical slurry crusher

Abstract

Provided is a vertical slurry crusher. The vertical slurry crusher comprises a crushing assembly driven by a rotating shaft (4). The crushing assembly comprises a barrel (1) and a rotor (2), the barrel (1) is provided with a screen net area (5), the inner wall of the barrel (1) is provided with a plurality of raised fixed teeth (7), and multiple rows of the raised fixed teeth (7) are arranged along the inner wall of the barrel (1). Each row comprises a plurality of the raised fixed teeth (7) arranged vertically, and a vacant section (8) is arranged between every two adjacent rows of the raisedfixed teeth (7) as a space needed for material falling. A plurality of raised rotary teeth (9) are arranged on the periphery of the rotor (2), at least two rows of the raised rotary teeth (9) are arranged along the periphery of the rotor (2), each row comprises a plurality of the raised rotary teeth (9) arranged vertically, and a vacant groove (23) is arranged between every two adjacent rows of the raised rotary teeth (9) as a space needed for material falling. The space needed for the sizes of material target particles is reserved between the meshing raised rotary teeth (9) and the raised fixed teeth (7). The crushed material particles are even, and the crushing efficiency is high.

Description

technical field [0001] The invention belongs to the technical field of pulverizer manufacturing, and in particular relates to a vertical slurry pulverizer. Background technique [0002] The pulverizer is a machine that pulverizes large-sized solid materials to the required size. Generally, solid and liquid are mixed during pulverization. It is widely used in chemical industry, metallurgy, plastics, food, pharmaceuticals, construction and other fields. Coarse crushers are mainly used for crushing pretreatment in various industries, and their main function is to process materials with larger diameters into granular materials with smaller diameters. There are four kinds of external forces applied to the material during the crushing process: rolling, shearing, impact (strike), and grinding. Rolling is mainly used for coarse and medium crushing, suitable for crushing hard materials and large blocks; shearing is mainly used for crushing or crushing, suitable for crushing tough or...

AI Technical Summary

Problems solved by technology

Therefore, the pulverizers of the prior art always have the following defects: the one is that the pulverized materials are of different sizes, very uneven, and the fine powder content is relatively high

The second defect of the prior art pulverizer is that the equipment occupies a large area and the pulverization efficiency is low
