A ball mill is a type of grinder used to grind or blend materials for use in mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser sintering. It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell.

A singlecompartment mill entails a premilled feed for proper operation, whereas a twocompartment mill yields a finer cement product than a threecompartment mill. Uniform mass distribution of balls led to slightly finer product than uniform surface area or number distributions, while the impact of a classifying liner was negligibly small.

For example, the comminution process of cement clinker followed the firstorder grinding kinetics with the balls and rod media. Meanwhile, the grinding rate of the rod mill was higher than the ball mill [22]. The equivalent granule size declined while its specific surface area increased gradually with grinding time [23].

3A: Ball Mill Fundamentals. Ball Mill Dynamics The basic objectives of ball milling is the size reduction of materials, called comminution. Size reduction in a ball mill is achieved primarily by the motion of the balls in the mill. By rotation, the mill elevates the ball charge and material and drops the load upon itself.. Comminution Mechanisms

Then in ballwear formula (25), T = /K Log10 Da/Db; but from (29), K = Rt/Wt. Then T = /Rt Log10 Da/Db T is 1 day, Wt is the original weight of the ball charge, and Rt is the ball wear for one day. Then Log10 Da/Db = Rt/ are all known, and it is only necessary to solve for Db, the diameter of the balls to be added.
