اقرأ أكثرBall mills are used for grinding of rocks, cement clinker and limestone from 10 to 100 mm feed sizes down to sub-millimetre product. They are typically rotating cylinders with diameters from 3 to 6 m and lengths from 6 to 12 m. The flow of particulate solids within these mills can be modelled using the discrete element method (DEM).
