Ball mills are usually operated at 75% of the critical speed. The critical speed is the speed where, mathematically calculated, the grinding media would centrifuge out. Mills of 2 m in diameter therefore rotate in operation at about 23 revolutions per minute, which corresponds to a .-Grinding balls-Grinding balls-Ningguo City Weida .Grinding balls-Ningguo City Weida Casting Co., Ltd.: Telephone:+ Mobile/whatapp:+86 Email:[email protected] Address:Heli Industry Economic Development Zone Ningguo City, Xuancheng, Anhui, ChinaWhat Is a Ball Mill? - Monroe EngineeringFor a ball mill to work, critical speed must be achieved. Critical speed refers to the speed at which the enclosed balls begin to rotate along the inner walls of the ball mill. If a ball mill fails to reach critical speed, the balls will remain stationary at the bottom where they have little or no impact on the material.Ball Mill For Mineral - mining project knowloadgeBall mills are usually operated at 75% of the critical speed.
