Ball Mill for Copper ore Grinding in Russia. As mentioned above, the most popular copper ore grinding mill used in Russia's copper mining industry is ball mill.
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.
