What Are the Differences between Dry and Wet Type Ball Mill?

The water can wash away the fine particles in time to avoid over-grinding. The wet ball mill has a low noise, and low environmental pollution. The wet ball mill has a simple transportation device with less auxiliary equipment, so the investment is about 5%-10% lower than that of a dry ball mill. The grinding particle size is fine and uniform.

Differences in dry and wet grinding with a high solid ...

However, for higher solid concentrations (≥50 vol.%), the wet grinding breakage rates were smaller than the dry grinding ones. As the solid concentration increased, the viscosity of the suspension increased significantly, which resulted in the adsorption of particles onto the inner surfaces of the mills [14].
