Ball mill - an overview sciencedirect topics. the ball mill is a tumbling mill that uses steel balls as the grinding media. the length of the cylindrical shell is usually 11.5 times the shell diameter figure 8.11.the feed can be dry, with less than 3 moisture to minimize ball coating, or slurry containing 2040 water by weight. get price
Intermediate and fine size reduction by grinding is frequently achieved in a ball mill in which the length of the cylindrical shell is usually 1 to 1.5 times the shell diameter. ball mills of greater length are termed tube mills, and when hard pebbles rather than steel balls are used for the grinding media, the mills are known as pebble mills. in general, ball mills can be operated either wet or dry and are capable
