### Ball Mill Critical Speed - Mineral Processing & Metallurgy

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 itsCritical Speed Of Ball Mill Calculation India,Liner in a Ball Mill; Mill size: >52m x 106m; Ball size: 30mm; Mill speed: 70% of critical speed jaw crusher, cone crusher, impact crusher, mobile crusher,grinding iron ore ball mill in india Mill Critical Speed Calculation,The speed of the mill was kept at 63% of the critical speed The face angle was varied from 90 to 111 degrees for the three types of configuration 1, 2 and 4, as shown in the figure Also, the height of the lifter bar in configuration 3 was changed to observe the trajectory It was observed that the ball trajectories could be controlled by the face angle and the height of the lifter bars
