- grinding ball selection method for iron ball mill

The processing capacity of ball mills and rod mills is usually calculated by volumetric method or power consumption method, and the selection of ore mill should meet the following requirements: 1) Rod mills are mostly used for rough grinding, with a discharge particle size of 1~3mm, which can be ground to 0.5mm in a gravity separation plant.

MoreA ball mill is a drum-grinding unit where balls from solid materials (steel, iron, hard alloys, ceramics, etc) are used. Most common are ball mills, where when the drum rotates and the balls rub against the inner walls, the balls are lifted until the lifting angle becomes bigger than the angle of repose. Then the grinding media are again below.
