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 Mills
nbsp 0183 32 If 75 percent of critical speed is considered desirable for efficient grinding in a 2 4 meter 8 foot diameter mill then the same will be true for a 5 0 meter 15 189 foot diameter mill
Common types of grinding mills include Ball Mills and Rod Mills This includes all rotating mills with heavy grinding media loads This article focuses on ball and rod mills excluding SAG and AG mills Although their concepts are very similar they are not discussed here Photographs of a glass ended laboratory ball mill show action of ball mass within the mill
Critical Speed On A Ball Mill We are a large scale manufacturer specializing in producing various mining machines including different types of sand and gravel equipment milling equipment mineral processing equipment and
The point where the mill becomes a centrifuge is called the quot Critical Speed quot and ball mills usually operate at 65 to 75 of the critical speed Ball Mills are generally used to grind material 1 4 inch and finer down to the particle size of 20 to 75 microns
