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 Get price
