The grinding process in ball mills is notoriously known to be highly inefficient only 1 to 2 of the inputted electrical energy serves for creating new surfaces.
A specific energy-based size reduction model for batch grinding ball mills was reported in a previous paper Shi and Xie, 2015. A discharge function modified from the Whiten classification efficiency equation has been incorporated in the size reduction model to extend its applications from batch grinding to continuous operation.
Jun 06, 2013 For this reason, funded research for possible efficiency gains from low ball charge filling levels was not allowed by the corporation they worked for. To put maximum energy between the trunnion bearings in a short distance required a high filling level in the mill, making the actual grinding efficiency a secondary concern.

Dec 18, 2013 Fine grinding, to P80 sizes as low as 7 m, 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 mills energy budget.
The savings in energy and the increase in grinding efficiency provided by Attritors are substantial. The graph below compares various mills during the high energy ball milling process. Select a link to learn more about these Attritor-style stirred ball mills Dry Grinding Continuous or Batch Mode.
Ball size will also affect the grind P80. Efficiency is in part determined by the Axb value of the ore. A small lab mill can give guidance on the influence of ore strength and ball size. Larger balls will increase P80 in ball mill, thereby reducing overgrinding.
Jun 01, 2009 The work using a vertical shaft stirred mill compared with Bond ball mill, both operated in closed circuit with a classifier, demonstrated a clear trend that on average 30 energy saving can be expected by using the stirred mill to replace ball mill for coarse grinding from a top particle size 3.35 mm to P 80 less than 100 m.
In the range of 45-65 solids, typically used in ball mill circuits, cyclone classification efficiency is commonly lower than 50. This has an adverse effect on ball mill circuit capacity as shown by work conducted by Hukki and his co-authors 1965, 1968, 1973, 1979.
