Photo of a 10 Ft diameter by 32 Ft long ball mill in a Cement Plant. Photo of a series of ball mills in a Copper Plant, grinding the ore for flotation.The point where the mill becomes a centrifuge is called the Critical Speed , and ball mills usually operate at 65 to 75 of the critical speed. Ball mill Working Principle The ball mill is a horizontal rotating device transmitted by the outer gear. The materials are transferred to the grinding chamber through the quill shaft uniformly.Aug 01, 2021 So for an effective grinding, the ball mill should be operated at a speed (optimum speed) equal to 50 to 75 percent of the critical speed. (e) Level of the material in the mill A low level of material in the mill results into a reduction in the power consumption.
Speed of ball mill Media size and shape Since the optimum number of revolutions per minute (rpm) for a ball mill is directly related to the ball mill radius, these two factors are grouped together to study.
