heat generated in the crusher. At most operations, water is sprayed into a crusher and onto conveyor belts to suppress dust in the plant, but this usage represents only a small fraction of the plant's total water usage. The crushed ore is transferred to a semiautogenous (SAG) mill or ball mill where the ore is further reduced in size.
