It often uses a stage grinding process when processing nickel ore. The crushed products enter the ball mill for a stage of grinding and then enter the spiral classifier for pre-classification. If the ore particle size of nickel ore is too coarse (greater than 0.1mm) or too fine (less than 0.006mm), it is unfavorable for the subsequent flotation.

Grinding tests were conducted on an oxidized copper-cobalt ore using a pear-shaped ball mill. Twelve mono-sized ore fractions were prepared and wet ground batchwise. The mill was run for 0.5 to 30 min intervals. The shortest interval provided data more closely related to the breakage function (B) because less secondary breakage was hypothesized.
