OIn order to improve the dressing production ability and mining equipment potential, ore crushing process is transformed so that the utilization factor of ore grinding machine will be improved. The major measures are that more crushed and less ground to reduce the grain size of grinding ores.
The ore is conveyed, and lime is added (2) to raise the pH of the ore. Following crushing through a jaw crusher (3), the ore is fed into the semi autogenous grinding (SAG) mill (4) along with water and steel balls. The grinding process reduces the rock to a slurry. The SAG mill is a large revolving cylinder.
Selective grinding refers to a kind of grinding phenomenon in which the ore fragmentation degrees is different in the grinding process due to the difference in hardness between minerals. The main purpose of the crushing and grinding operation is not to reduce the ore particle size, but to dissociate the useful minerals from the gangue minerals.
