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
