Chat OnlineSpeed of rotation of mill; at low speeds, the balls simply roll over one another and little grinding is obtained while at very high speeds, the balls are simply carried along the walls of the shells and little or no grinding takes place, so for an effective grinding, the ball mill should be operated at a speed that is optimum speed equal to 50.
Chat OnlineExperiments are designed using taguchi method to find the optimum parameters for silica sand nanoparticles production using low speed ball milling.Orthogonal array and signal-to-noise ratio are applied to study performance characteristics of machining parameters which are the ball to powder weight ratio, volume of milling jar, and rotation speed.
Chat OnlineBall 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 peripheral speed .
