Three types of tests are available for mill power determinations. In most cases one of two bench scale tests is adequate. First, a Jar Mill grindability test requires a 5 lb. (2 kg) sample and produces a direct measured specific energy (net Hphr/t) to grind from the design feed size to the required product size. The second test, a Bond Work Index determination, results in a specific energy ...
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 ...

Larger Capacity Ball Mills In Power Plant. In general, ball mills can be operated either wet or dry and are capable of producing products in the order of 100 m. 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 . Mill Grinding ...
· At the short ball mill grinding is a more rough and for grinding fineness a lot of material has to be returned from classifier to the mill, it leads to mill overload. In long ball mills the grinding occurs only at the front and the rest of the balls in the drum only increases power consumption. Drum mills have one grinding chamber (short and ...
