Grinding media characteristics (mass, density, number, ball size distribution); Speed of mill rotation; Slurry density when wet grinding . Charge Volume. Mill should not be overcharged or undercharged ; Overloading tends to accumulate fines at the toe of the mill which results in a cushioning effect. When the rock load is low, excessive ball-to-ball contact retards the rate of breakage. The

In general, ball mills can be operated either wet or dry and are capable of producing products in the order of 100 μm. This represents reduction ratios of as great as 100. Very large tonnages can be ground with these ball mills because they are very effective material handling devices. Ball mills are rated by power rather than capacity. Today

AG/SAG mills can accomplish the same size

Rotation speed of the cylinder. Several types of ball mills exist. They differ to an extent in their operating principle. They also differ in their maximum capacity of the milling vessel, ranging from 0.010 liters for planetary ball mills, mixer mills, or vibration ball mills to several 100 liters for horizontal rolling ball mills. Contents. 1 Pharmaceutical uses of Ball Mill; 2 Advantages of

The basic parameters used in ball mill design (power calculations), rod mill or any tumbling mill sizing are; material to be ground, characteristics, Bond Work Index, bulk density, specific density, desired mill tonnage capacity DTPH, operating % solids or pulp density, feed size as F80 and maximum ‘chunk size’, product size as P80 and maximum and finally the type of circuit open/closed
