A ball mill is a type of grinder used to grind blend and sometimes for mixing of materials for use in mineral dressing processes paints pyrotechnics ceramics and selective laser sintering It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell A ball mill consists of a hollow cylindrical shell rotati

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

Grinding time is related to media diameter and agitator speed via: T = KD 2 /N 1/2 where T is the grinding time to reach a certain median particle size K is a constant that depends upon the material being processed the type of media and the particular mill being used D is the diameter of the media and N is the shaft rpm This equation shows that total grinding time is directly
