    The grinding works on the principle of critical speed Critical speed can be understood as that speed after which the steel balls that are responsible for the grinding of particles start rotating along the direction of the cylindrical device, thus causing no further grinding Ball mills are used extensively in the mechanical alloying process in which they are used for grinding and for coldA Ball Mill grinds material by rotating a cylinder with steel or ceramic grinding balls, causing the balls to fall back into the cylinder and onto the material to be groundBall Mills have been successfully run at speeds between 60 and 90 percent of critical speedHowever, most Ball Mills operate at speeds between 65 and 75 percent of critical speedcritical speed of of ball mill
