Get PriceEmail contactThe balls which could be of different diameter occupy 30 – 50 % of the mill volume and its size depends on the feed and mill size. The large balls tend to break down the coarse feed materials and the smaller balls help to form fine product by reducing void spaces between the balls. Ball mills grind material by impact and attrition.

Ball mills – with small balls or cylpebs – can produce the finest product of all tumbling mills. 80% minus 74 microns is a normal requirement from the concentrators. The CRRK series of wet grinding ball mills are tabulated below. PEBBLE MILLS

Get PriceEmail contactThe 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.
