WhatsAppGet PriceGet A Quote8.3.2.2 Ball mills. The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 1–1.5 times the shell diameter ( Figure 8.11). The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 20–40% water by weight.
WhatsAppGet PriceGet A QuoteHow Does ball mill Work? Ball mills work by using balls to grind materials. Materials such as iron ore, pain and ceramics are added to the ball mill. As the ball bill rotates, the balls bounce around while striking the enclosed material. The force of these strikes helps to grind the material into a finer, less-coarse medium.
