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

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

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.
