What particle size range does ball mill grinding produce? - Quora

Ball mill grinding is one method of crushing ore to an appropriate size fraction. Specifically, ore is put into a large receptacle (a drum) and then it rotates slowly around. Inside the receptacle, there are balls, usually made of metal, that as the ore is rotated around the revolving drum the ore is crushed as the balls rise and fall.

MBMM Ball Mills - Variable Sized Material Reduction Equipment

The capacity, or throughput, of a ball mill, is directly linked to particle size of the ball mill discharge. For example, it takes approximately 3 times as long to achieve 200 mesh grind as it does to achieve 65 mesh grind. Establishing a commercial liberation size is critical when designing and engineering your grinding circuit.

The importance of feedrate control in size reduction - Jenike .

Size reduction, or comminution, plays an important role in many bulk solids processes in a wide range of industries. Depending on the industry served and the mechanisms used, size reduction may be called crushing, grinding, milling, pulveriz- ing, or slicing. It may be used to re- duce particle size or to increase.
