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

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.Web

Mill power for conical (Hardinge) type ball mills

It has been found that a change in density of 2.6 to 2.9 (an increase of density of 11.5%) gives a 1.5% increase in mill power for these conical mills, for Pb = 7.75. Inserting p51 = 2.6, Pb = 7.75 and solving for fc gives 0.445, and using the estimate for c, f ~ 1.0. Thus it appears that the powder in the mill is circulating in about the same ...Web
