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.
