The effect of ball size on breakage rate parameter in a

2009-6-1 · The mill was crashed-stopped during various periods. Samples were representatively taken from inside the mill in distances of 20–30. cm along the center and edge lengths for selected periods which are 2, 5, 10, 15, 20, 30, 45 and 60 min.. For modelling of grinding process in pilot scale ball mill, determination of the particle size distribution of feed and product of mill is an essential step.

Study on the Performance of Ball Mill with Liner

The breaking performance of the hemispherical lifter and the ladder lifter was poor, because the main pattern of motion was grinding rather than impact breakage. Secondly, the effects of the height–width ratio of the rectangular lifter, the height of the lifter and the number of lifters on the working efficiency of the ball mill were studied.

The energy efficiency of ball milling in comminution

2002-11-1 · In terms of this concept, the energy efficiency of the tumbling mill is as low as 1%, or less. For example, Lowrison (1974) reported that for a ball mill, the theoretical energy for size reduction (the free energy of the new surface produced during grinding) is 0.6% of the total energy supplied to the mill
