2021-7-11 · 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 CS rpm = 2676 / SQR( JarID mm -BallOD mm ). The material to be milled should be reduced to appr. 8 mesh prior
