Ball Mill (Ball Mills Explained) saVRee saVRee
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.The proposed utility model relates to devices for grinding solid materials, and is intended for use in the construction, chemical and metallurgical industries, as well as in agricultural production. The device contains a housing with end walls, a loading and unloading trunnion, a gear ring of the drive and a funnel, while at the ends of the drum in the area of the RU202529U1 Drum for ball mill Google Patents
