For each mill there is a critical speed that creates centrifuging Figure 37c of the With the help of Figure 38 2015 4.6.1 Low-speed mill. Mills operating below 75 rpm are known as low-speed mills.Low-speed units include ball or tube or drum mills which normally rotate at about 15–25 rpm.Other types of mills tube mill,

rod which differ from the standard R is derive ...The formula to calculate critical speed is given below. N c = 42.305 /sqt(D-d) N c = critical speed of the mill. D = mill diameter specified in meters. d = diameter of the ball. In practice Ball Mills are driven at a speed of 50-90% of the critical speed Rod mill e.g,
