Heat taken away by ventilation systems can accounts for roughly 20% of the total heat discharged by the ball mill. Improving that ventilation system brings more cool air into the inside of the ball bill, gradually reducing the internal temperature. However, the major benefit of using ball mills is the product fineness they can deliver.

The water can wash away the fine particles in time to avoid overgrinding. 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.
