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.

1. The feed material is introduced in the cylinder in such a quantity that it occupies 60% of the volume of cylinder.
2. A fixed no of balls are introduced and the cylinder is closed and the mill starts rotating
3. The speed of the rotation is important. At low speed, the balls will roll over each other and mostly only attrition will occur.
