Ball Mill Factors Acmas Technocracy

Speed 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 to 75 percent of the critical speed (the minimum speed at which centrifuging occurs is called the critical speed of the ball mill…
