Ball Mill Fractional Filling

Ball mills are giant drums that are filled to between 30 and 40 of their volume with freely moving grinding media in this case balls the diameter of the balls is between one and several centimetres to suit the application smaller balls for fine milling results and larger ones for coarser milling tasks.
