Ball mills grind material by impact and attrition. The degree of milling in a ball mill is influenced by; a. Residence time of the material in the mill chamber. b. The size, density, and number of the balls. c. The nature of the balls (hardness of the grinding material) d. Feed rate and feed level in the vessel. e. Rotation speed of the cylinder.

Ball mills are employed in the comminution stage as grinding machines ( size reduction ). The purpose of grinders in the mining industry is to reduce the feed material size in order to liberate the minerals from the barren rock. Ball mills are the most common grinding machine employed in the mining industry.

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.
