12. If the rate of feed increased, coarser product will be obtained and if speed of rotation is increased the fineness for a given capacity is increases. During grinding, the balls themselves wear and are continuously replaced by new ones so that mill contains balls of various ages. Ball mill produces 1 to 50 ton/hr of powder and energy requirement of the ball mill is about 16 kwh/ton.
