How to Deal Coal Gangue with Stone Crushing Plant?

Since coal gangue is watered and mud is produced during the crushing process, cone crusher is easy to be blocked and work inefficiently. Besides, since screen is pasted by mud, the whole crushing process works in a poor way. To alleviate the burden on cone crusher, we equip it with a jaw crusher for coarse and open crushing.

Besides, to improve the screening efficiency, we can change the banana vibrating screen to linear vibrating screen. By doing so, we can see some effects but the fundamental problems can not be solved. After working for a certain period, we can change the jaw crusher to 8mm linear vibrating screen.

There are many ways to crush the coal gangue and each has its advantages and disadvantages. We should select different process and equipment according to the mineral kinds. If materials to be processed are washing gangue in coal preparation plant, we can use the two-stage, wet and open crushing process.

Probability screen is suitable for screening in advance. Jaw crusher is for primary crushing and hammer crusher for tertiary crushing. If materials to be processed are pyrite ores, we can use the three-stage, wet and closed crushing process. Jaw crusher machine is for coarse crushing and impact crusher is suitable for secondary and tertiary crushing.
