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

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. The wet ball milling can not only grind agglomerate into fine particles, but also mix the lean material and the plastic material …
