Dry grinding of the ball mill requires that the material in the mill is dry, and no water or other liquids can be added. The material is ground by the medium of the ball mill in the mill, and the products that meet the requirements are carried out by the wind or airflow. The main equipment of the wet grinding of the ball mill is a wet ball mill.

The operating principle of autogenous mill is essentially the same as that of ball mill. Most remarkably, the crude ore from stope or the coarsely crushed ore can be directly fed into the grinding mill. The autogenous mill will grind the material to the extent that the content of the particles with particle size <0.074 mm accounts for 20–50% ...

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.
