The product particle size is 1~3mm. When used for rough grinding, choose a rod mill. The product particle size is less than 0.5mm. When used for fine grinding, choose a ball mill. The product of the rod mill is rougher but more uniform than the ball mill's. According to the production method.
Crushed ore is fed to the ball mill through the inlet; a scoop (small screw conveyor) ensures the feed is constant. For both wet and dry ball mills, the ball mill is charged to approximately 33% with balls (range 30-45%). Pulp (crushed ore and water) fills another 15% of the drum's volume so that the total volume of the drum is 50% charged.
