Analysis of the Loading Capacity of Ball Material

Ball material which is large than a warehouse grinding mill medium and its ratio is higher than the weight of the material. It illustrates that the grinding process in the mill loads how much the memory quantity is, it also shows the degree of uniformity to the feed in case of a mill normal operation. The materials with the ball mill are filled in the gap between the grinding mediums, the theory refers to small grains.When 100% of the voids of abrasive barrel material grams fill the mill's production capacity , it reaches the maximum and thus make use of energy efficiently.

Experiments have confirmed that 14.2% of the material in grinding barrel do not have much weight .The ball feed ratio is approximately equal to 7 depending on the experience of some small factory production and that of the closed-circuit mill should be lower.Practice has proved that by exposing the little material surface half ball, steel ball in the rough grinding positions is appropriate when the operation of the mill is normal, finely ground positions should be buried in the material below 1-2cm.

When the mill ball feed ratio is big, it will increase the impact of friction between the grinding barrel and the liner. So that power consumption will increase the ball consumption in lower yields, when the ball-to-powder ratio is small, this indicates that excessive grind memory material will be produced.The buffer effect will reduce grinding efficiency. The ball feed ratio determines actual measurement method, the calculation method and the amount of storage calculation.
