feed of ball mill

The balls which could be of different diameter occupy 30 50 of the mill volume and its size depends on the feed and mill size The large balls tend to break down the coarse feed materials and the smaller balls help to form fine product by reducing void spaces between the balls Ball mills grind material by impact and attrition

Ball mills give a controlled final grind and produce flotation feed of a uniform size Ball mills tumble iron or steel balls with the ore The balls are initially 5–10 cm diameter but gradually wear away as grinding of the ore proceeds The feed to ball mills dry basis is typically 75 vol ore and 25 steel

A ball mill efficiently operated performs a wide variety of services In small milling plants where simplicity is most essential it is not economical to use more than single stage crushing because the SteelHead Ball or Rod Mill will take up to 2″ feed and grind it to the desired fineness In larger plants where several stages of coarse and fine crushing are used it is customary to crush from 12″ to as
