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.
: 60% cylinder filled with material. Remaining balls are introduced to cylinder. And closed it with lid. Mills are allowed to rotate on axis. Speed of rotation play important role. At low speed, balls roll over each other and size reduction not occur at optimum level. At high speed, ball will stick to the wall of cylinder and no size reduction occur. At correct speed (optimum speed ...

MILL • A ball mill consists of a hollow cylindrical shell rotating about its axis. The axis of the shell may be either horizontal or at a small angle to the horizontal. • It is partially filled with balls. The grinding media is the balls, which may be made of steel (chrome steel), stainless steel, ceramic, or rubber.
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.
