The starting point for ball mill media and liquid charging is generally as follows: 50% media charge. Assuming 26% void space between spherical balls 50% x 26% = 13% free space. Add to this another 45% to 50% above the ball charge for total of 58% ...
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.
1. The jack up device of wet grate ball mill makes maintenance easy. 2. The hydrostatic and hydrodynamic bearings ensure the smooth operation of wet grate ball mill. 3. The low speed transmission of wet grate ball mill contributes to easy overhaul and maintenance. 4. The oil mist lubrication device guarantees reliable performance of bearings. 5.
The advantages Wet ball milling has over dry milling are higher energy efficiency, lower magnitude of excess enthalpy, better heat dissipation and absence of dust formation because of the aqueous environment it is being performed. Particle Size Reduction. Milling the powder in the wet or dry state produces different results.
