Further research is required to include a wear parameter that indies the liner profile in Morell's Model C power equations. It is also necessary to carry out additional research on variable speed drivers (VSD) for mill motors, which could potentially pay back the cost of adding a VSD on ball mills due to the increased grinding efficiency.

الحصول على السعرThe DEM results are shown to be highly consistent with the experimental results. The torque of liners and baffles are affected by lifter height, lifter number, and mill speed. Moreover, the changes in the torque and power consumption of a ball mill can be effectively explained using two important factors: lifter and particle area ratio.
الحصول على السعرAug 08, 2018 · The performance of a ball mill is known to be affected by the design of the liners. A proper liner must key the ball charge to the mill shell in order to maximize the tumbling action with a minimum of slippage, and at the same time it must protect the mill shell from damage. There are two important features that are common to all three figures.
الحصول على السعرThe ratio of the barrel length to the diameter of the ball mill is small, and in most cases the ratio is only slightly greater than addition, the barrel mill speed is lower than the working speed of the same size ball mill, so that the medium inside is in a sloping state. 2.
