Coarse crushing and sorting process

Abstract

The invention discloses a coarse gain crushing and separation process. The coarse gain crushing and separation process includes the steps that S01, materials are crushed while conveyed on a screen net of a crusher which is provided with a material moving hammer or material moving plate hammer and capable of realizing internal classification, the materials screened out of the screen net are discharged from a first outlet of the crusher which is provided with the material moving hammer or material moving plate hammer and capable of realizing internal classification, and the materials not screened out of the screen net are conveyed to a second outlet of the crusher which is provided with the material moving hammer or material moving plate hammer and capable of realizing internal classification along the screen net and then discharged; S02, the materials discharged from the second outlet are separated through a gas separator; S03, if the granularity of the separated-out materials is larger than preset granularity, part of the materials are returned to the step S01 to be treated; if the granularity of the separated-out materials is smaller than the preset granularity, the materials are classified into coarse grain products, or classified into coarse grain products and fine grain products. By carrying out coarse gain separation through the process, the production efficiency is improved, the yield is high, energy consumption is low, and the degree of abrasion to equipment is low.

Description

technical field [0001] The invention relates to the technical field of material separation, in particular to a coarse particle separation process. Background technique [0002] In modern production, there are a large number of solid materials that need to be crushed and the crushed materials are classified into particles. Currently, screening is generally only suitable for materials with a particle size of less than 1 mm and a larger specific gravity. The process of processing. [0003] However, the screening capacity in the prior art is small and the process is complicated. In addition, because the screening process in the prior art cannot discharge a large number of qualified particles in time, the output of the entire screening system is reduced and the power consumption is large, and The screen is more worn. [0004] Therefore, how to solve the technical problems of low efficiency, low output, high energy consumption and high wear of the screening process in the prior ...
