Abstract

The invention belongs to the technical field of screening and crushing, and particularly relates to a multi-stage crusher device with a screening function. By adoption of the multi-stage crusher device with the screening function, the problems that in the prior art, a crushing device is simple, cannot effectively and reasonably screen crushed coal briquettes and is low in speed; and a large quantity of manpower and material resources are needed for screening after crushing, the production speed is severely decreased, and consequentially, the work efficiency is low, and the production cost is high are solved. To solve the technical problems, the multi-stage crusher device with the screening function comprises a feeding port, a discharging port, a crushing and screening device, an observation window and a fixed rack. The multi-stage crusher device with the screening function has the effects being high in crushing efficiency, reasonable in screening, capable of saving time and labor and beneficial to 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...
