the rotational speed of the milling jar should be 65 of the critical speed of the jar. the critical speed is the speed when a ball mill becomes a centrifuge and may be calculated for a specific jar and ball diameters as follows csrpm 2676 / sqr( jaridmm-ballodmm ). the material to be milled should be reduced to appr. 8 mesh prior

Ball mill the centrifugal forces caused by

Ball Mill The Centrifugal Forces Caused By

for ball milling, there is an optimum speed where the centrifugal force at the top of the mill is just balanced by the force of gravity. this caused the balls to be lifted to the maximum height before they fall onto the balls below, thus imparting the most kinetic energy. in practice, the ball mill is run at just below this speed (7080).
