    how to calculate the ball mill speed 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 its position onto the shell. The basic parameters used in ball mill design (power calculations), rod mill or any tumbling mill sizing are material to be ground, characteristics, Bond Work Index, bulk density, specific density, desired mill tonnage capacity DTPH, operating solids or pulp density, feed size as F80 and maximum chunk size , product size as P80 and maximum and finally the type of circuit open/closed

  • SAGMILLING . . Mill Critical Speed Determination

    The "Critical Speed" for a grinding mill is defined as the rotational speed where centrifugal forces equal gravitational forces at the mill shell s inside surface. This is the rotational speed where balls will not fall away from the mill s shell. Mill Inside Diameter Enter the mill diameter inside the shell (excluding liners). Centrifugal force is related to the rotational speed of ball mill. The higher speed is, the bigger centrifugal force is. The higher speed of ball mill is, the bigger centrifugal force is. When it increases to the critical speed, steel ball will not fall down and do a circular motion with the cylinder.
