Grinding Test. In this paper, the wet ball milling process was used in the laboratory ball milling test. Before grinding, the ball mill was kept idle for 10 minutes and then washed together with the grinding media. Three types of ores were crushed and separated by a jaw crusher, and the ground particle size of 2 mm was selected.

Grinding machine has been widely used in gold mines in South Africa since 1905. At that time, the grinding machine used river pebble as the grinding medium, which was essentially a gravel mill. Later, in order to improve the production capacity of the mill, cast iron balls were used as the medium, so normal gravel mills were evolved into ball mills and rod mills.
