    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 ball milling. Proper milling time may be tested by taking and sieving samples during the

    The critical speed (rpm) is given by: n C = 42.29/ √ d, where d is the internal diameter in metres. Ball mills are normally operated at around 75% of critical speed, so a mill with diameter 5 metres will turn at around 14 rpm. The mill is usually divided into at least two chambers (although this depends upon feed input size - mills including
