Once you know the ideal speed of rotation for your mill jars, you will need to design your mill around this critical parameter. With most ball mill designs, you have two areas of speed reduction to tweak: from the motor drive shaft to the drive pulley and from the roller bar to the milling jar. The drive train calculator featured on this page ...

The drum of a mill rotates at 60–95 percent of the "critical speed of rotation" (n cr = / rpm, where D is the inside diameter of the drum in meters). When the critical speed of rotation is significantly exceeded, the grinding bodies are pressed to the side of the drum by centrifugal force, and grinding ceases. Operation above the critical speed of rotation requires smooth lining ...

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 test milling. During sampling it should be checked ...
