This ball charge depth is compared to the depth measured when the Vertimill was first commissioned with a new and full ball charge. Call us for help determining the correct level. One important side note - if the static ball charge rises by one foot (0.30 m) as compared to when it was first commissioned, in order to maintain the same 80% FLA ...

The main function of the steel ball in the ball mill is to impact crush the material and also play a certain grinding effect. Therefore, the purpose of grading steel balls is to meet the requirements of these two aspects. The quality of the crushing effect directly affects the grinding efficiency, and ultimately affects the output of the ball mill.

3mm balls than a bucket of 12 mm balls). The same effect should be seen when operating with slurry, yet the second graph in Figure 5 shows the opposite effect – both media types are reported to consume more energy using fine media in ore grinding ("UG2" platinum ore). This almost certainly indicates the tests

Fine grinding, to P80 sizes as low as 7 μm, is becoming increasingly important as mines treat ores with smaller liberation sizes. This grinding is typically done using stirred mills such as the Isamill or Stirred Media Detritor. While fine grinding consumes less energy than primary grinding, it can still account for a substantial part of a mill's energy budget. Overall …
