What Are the Differences between Dry and Wet Type Ball …

2021-10-28 · The water can wash away the fine particles in time to avoid over-grinding. 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.
