A ball mill for limestone is a type of grinder used to grind materials into very fine powder for use in ceramics, paints, pyrotechnics, and mineral dressing processes. By revolving a cylinder filled with grinding balls, the ball mill grinds the material by causing the balls to fall back into the cylinder.

However, the breakage rates for wet grinding with higher slurry densities are significantly less compared to those for dry grinding. As observed by Klimpel [18] and Tangsathitkulchai and Austin [15], the rapid increase in viscosity of the slurry for wet grinding is apparent, where a layer of particles begins to deposit around the inner mill wall.
