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 centimeters to suit the application – smaller pearls for fine grinding results and larger ones for coarser grinding tasks. The drive sets the grinding drum into slow rotation, whereby the bed of ...
