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.



the fillings of 15-45% and mill speeds of 60 – 105% indicate that the various changes in load behaviour such as cataracting, centrifuging, ball packing and toe and shoulder responses were easily distinguished in probes responses. further tests were conducted in a mill with a 20% ball filling with increasing coarse or fine silica sand particle filling from 0 – 150% at the mill speeds of 63-98% of the critical mill speed.
