The F.C. Bond Ball Mill is a small universal laboratory mill used in calculating the grindability of all ores. GRINDABILITY IS THE NUMBER OF NET GRAMS OF SCREEN UNDERSIZE PRODUCED PER REVOLUTION. This Ball Mill can be used for units of time (hours, minutes) or it can be used for any number of revolutions, according to the type of grind desired.

The grinding is the last stage of comminution in a mineral processing plant, responsible for reducing particles in size by mechanisms of fragmentation, impact, compression, and shear. Moreover, it is one of the stages that requires greater focus due to the more energy-consuming and major investments requirements. The grinding is considered very important for the mineral concentration process

The basic parameters used in ball mill design (power calculations), rod mill or any tumbling mill sizing are; material to be ground, characteristics, Bond Work Index, bulk density, specific density, desired mill tonnage capacity DTPH, operating % solids or pulp density, feed size as F80 and maximum ‘chunk size’, product size as P80 and maximum and finally the type of circuit open/closed

The efficiency of the reduction machine may also influence the operating work index. For instance, a ball mill grinding an ore from 80 per cent-14 mesh to 80 per cent- 100 mesh will have a lower operating Wi value with 1.5-in. grinding balls than with oversize 3-in. balls.
