What is critical speed in a ball mill. the critical speed is used for the determination of ball mill ideal operating speed. but for comparison, rod mills would operate between 50 to 95 of the critical speed. the faster the mill speed, the greater the wear on the rods and liners. so, the general rule of thumb for rod mills is to.
Ensp;ensp;if the peripheral speed of the mill is too great it begins to act like a centrifuge and the balls do not fall back but stay on the perimeter of the mill. the point where the mill becomes a centrifuge is called the quot;critical speedquot; and ball mills usually operate at 65 to 75 of the critical.
A ball mill critical speed (actually ball rod ag or sag) is the speed at which the centrifugal forces equal gravitational forces at the mill shell s inside surface and no balls will fall from its position onto the shell. chat online; hindi ball mill hammer mill critical speed of ball.
Aug 06, 2015 milling method uses ball mill, rod mill, impact mill, etc to produce powders of required grade and fineness. if speed of rotation is low, it results in insignificant milling action as balls only move in lower part of the drum. if speed of rotation is very high, the balls cling to the drum walls due to centrifugal.
