First, a Jar Mill Grindability Test requires a 5 lb. (2 kg) sample and produces a direct measured specific energy (net Hphr/t) to grind from the design feed size to the required product size. The second test, a Bond Work Index determination, results in a specific energy value (net Hphr/t) from an empirical formula.

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 appliion – smaller balls for fine milling results and larger ones for coarser milling tasks.
