1. Ball Mill Application :
Ball mill is the key equipment for secondary grinding after crushing. And it is suitable for grinding all kinds of ores and other materials, no matter wet grinding or dry grinding. Besides, it is mainly applied in many industries, such as ferrous&non-ferrous metal mine, building materials, chemical, electric power, coal, traffic, light industry, etc.According to different discharging ways, it can be divided into two kinds, grate type and overflow type.

Ball Mill is used to process gold stone, gold rock, gold ores in gold mining industry also.
2. Ball Mill Components:
Ball mills consist of the following components:Inlet, Discharge, Drum, Ring Gear, Electric Motor, Gearbox, Bearings
3. Ball Mill Working Principle:
Add balls into the ball drum to approximately 33%. As the ball mill rotates, the balls 'stick' to the inner surface of the ball drum due to the centrifugal force and are lifted on the rising side. At a certain angle, balls cascade down to the centerline of the ball mill because gravity overcomes the centrifugal force. And the ore is reduced to the required size by impact (balls impacting with the ore) and attrition (ore rubbing against other bits of ore and the milling balls).
