The main role of liners is to protect the mill shell from possible damage resulting from collisions with the balls. Unlike in laboratory ball mills, various designs in liner shape, including lifting and classifying liners, have been developed to increase milling performance in fullscale production mills.

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.
