of Ball Mill The working principle of the wet ball mill is similar to that of the dry ball mill, but there are differences. The wet ball mill needs to add an appropriate amount of water or absolute ethanol during the grinding process, which means that there are certain requirements for the concentration of grinding. The amount of water is
