the development of material grinding ball in ballmill
A 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. The first step is to study the imported materials used for ball grinding and. liners to determine their chemical . composition by means of Spectrometer testing. After spectrometer testing was conducted it is known that the material used in the imported grinding balls and liners contain carbon (C) above 2.1%, it can be concluded that the material
