Ball Mill Introduction . There are three main stages to mineral processing in the mining industry.These are: Comminution (crushing and grinding).; Beneficiation (separation and concentration).; Smelting and refining.; Ball mills are employed in the comminution stage as grinding machines (size reduction).The purpose of grinders in the mining industry is to …

the process of converting coal into coke using the by-product coke oven, the volatile matter in the coal is vaporized and driven off. This volatile matter leaves the coke oven chambers as hot, raw coke oven gas. After leaving the coke oven chambers, the raw coke oven gas is cooled which results in a liquid condensate stream and a gas stream.

The BTM is a low-speed mill that primarily grinds coal by impact and attrition. The VRM is a medium- speed mill that grinds coal by compression and, because of the low coal inventory in the mill and flat grinding surfaces, develops shearing action as well. For both mills a constant centrifugal force is maintained. The speed
