Ball millsproduce fine particles with a uniform size for flotation, itsgrinding mediascommonly are steel ball. Theball millrollsgrindingmedia together with the ore, as the oregrinds, these balls initially 5-10 cm in diameter but gradually wear out.Grindingis always carried out under wet conditions, with about 70% solid mixture in water. This procedure maximizes ore production and minimizes power consumption.
