Feb 20, 2017· Theball millis key equipment ingrindingindustry, especially in mineral ore dressing plants. It is widely used for thecement, the silicate product, new type building material, fire-proof material, chemical fertilizer, black and non-ferrous metal, glass, ceramics and etc.
Smaller plants tend to add extra crushing stages in order to operate a singlegrinding stageonly. If aball milluses little or no water duringgrinding, it is a ‘dry’mill. If aball milluses water duringgrinding, it is a ‘wet’mill. A typicalball millwill have a drum length that is 1 or 1.5 times thedrum diameter.
