What Is a Ball Mill and How Does It Work?
A ball mill and a tumbling mill are both types of grinding mills used to reduce material size. We mainly use a ball mill for mixing and grinding processes. In contrast, we generally use a tumbling mill for finer material reduction. What are the balls? Ball mills grind materials into an extremely fine form.

Moreover, two models were developed to use ceramic balls instead of cylpebs as fine-grinding media in the wet tumbling mill based on the ball size and the ratio of the total mass of cylpebs. Cylpebs can be replaced by ceramic balls with 1.16–1.75 times the diameter of cylpebs, taking up only 76%–83% of the total weight of cylpebs.
