Rod mill charges usually occupy about 45% of the internal volume of the mill. A closely packed charge of single sized rods will have a porosity of 9.3%. With a mixed charge of small and large diameter rods, the porosity of a static load could be reduced even further. However, close packing of the charge rarely occurs and an operating bed

3D simulation of charge motion in tumbling mills by the. Apr 18, 2001 The mill charge was made up of 5.08-cm diameter steel balls. A transparent Plexiglas™ faceplate enabled photographing the tumbling charge. The mill was operated at 30%, 50% and 70% of critical speed for two levels of mill filling (20% and 30% by volume).

1970s in 1975 centrifugal mills were invented for ultra fine grinding by exploiting centrifugal forces generated by gyration of the axis of the mill tube in a circlethe mill charge motion depends on the ratio of the gyration diameter to the mill diameter varying from a motion similar to that of a conventional tumbling media mill to that of a vibration mill.

Milling in an attrition mill (Fig. 24) is effected by the stirring action of an agitator that has a vertical rotating shaft with horizontal arms. This motion causes a differential movement between the balls and the material being milled, thus providing a substantially higher degree of surface contact than is achieved in tumbler or vibratory mills.

An essential part of this process is the validation of predictions from such models. Here we present detailed comparisons of the charge behaviour in a centrifugal mill predicted by DEM with high speed photographs obtained in an experimental mill. Excellent correspondence is generally obtained both for the charge motion and the power predictions.

Charge motion in a centrifugal mill loaded to around 45% and mill rotation of 695 rpm for G/D=2 (photograph on the left and simulation on the right). Comparing these results for G / D =2 to those for G / D =0.4 (in Fig. 4 ) for a similar fill level, we again find that the increased centrifugal force due to the arm rotation has significantly flattened the charge profile.
