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.

Wet ball milling has several advantages over dry ball milling. Let's explore some of them: 1. Better Grinding Efficiency The liquid in wet ball milling acts as a lubricant, reducing friction and improving the grinding efficiency. The particles are more effectively ground and dispersed, resulting in a finer particle size distribution. 2.
