A multi-stage screening crusher device

Abstract

The invention belongs to the technical field of screening and crushing, and specifically relates to a multi-stage screening crusher device. The present invention aims to solve the problem that in the existing technology, the crushing device is often relatively simple, and cannot effectively screen the crushed coal reasonably. The speed is slow, and the screening after crushing not only requires a lot of manpower and material resources, but also causes a huge lag in production, resulting in low work efficiency and waste of production costs. In order to solve the above technical problems, the present invention proposes such a multi-stage The screening crusher device includes a material inlet, a material outlet, a crushing and screening device, an observation window and a fixed frame. The invention has the effects of high crushing efficiency, reasonable screening, time-saving and labor-saving, and convenient reprocessing.

Description

technical field [0001] The invention belongs to the technical field of screening and crushing, and in particular relates to a multi-stage screening and crushing device. Background technique [0002] With the development of science and technology, people's life and production needs are increasingly inseparable from coal. The use of coal is extremely extensive, involving people's home life, chemical production, vitality power generation and many other fields. According to different occasions, coal The size of the coal often affects its utilization rate and production efficiency. Therefore, it is necessary to properly crush the coal block before use. However, in the existing technology, the crushing device is often relatively simple and cannot effectively crush the crushed coal block. Reasonable screening and slow speed. Screening after crushing not only requires a lot of manpower and material resources, but also causes a huge lag in production needs, resulting in low work effi...
