The diameter of the large ball is divided into 120mm and 100mm, the diameter of the medium ball is 80mm, and the diameter of the small ball is divided into two types: 60mm and 40mm. Under normal circumstances, it is not necessary to add small balls when the ...
Batch grinding was like open-circuit grinding when the amounts of media, ore, and water in the mill were the same. The types of grind, capacities, efficiencies, and powers were the same. Rods did more grinding than an equal volume of balls, but more power was required. Rods of extremely small diameter gave more selective grinding than large balls.
