Ball Mill Power CalculationExample #1. Awet grinding ball millin closed circuit is to be fed 100 TPH of a material with a work index of 15 and asize distributionof 80% passing ¼ inch (6350 microns). The required productsize distributionis to be 80% passing 100 mesh (149 microns). In order to determine thepower requirement, the steps are as follows:
[email protected]Thepower calculatedon using equation 1, (Bond, 1961; Rowland and Kjos, 1978), relates to: 1)Rod milling– arod millwith a diameter of 2.44 meters, inside new liners,grinding wetin open circuit. 2)Ball milling– aball millwith a diameter of 2.44 meters, inside new liners,grinding wetin open circuit.
Based on his work, thisformulacan be derived forball diameter sizingand selection: Dm <= 6 (log dk) * d^0.5 where D m = the diameter of thesingle-sized ballsinmm.d = the diameter of the largest chunks of ore in themill feedin mm.
1Calculationofball millcapacity. The production capacity of theball millis determined by the amount of material required to be ground, and it must have a certain margin when designing and selecting. There are many factors affecting the production capacity of theball mill, in addition to the nature of the material (grainsize, hardness, density, temperature and humidity), the degree of ...

The rods grind the ore by tumbling within the themill, similar to thegrindingballs in aball mill. To prevent the conditions leading to rod charge tangling, the length to diameter ratio is maintained at 1.4 to 1.6. Rodmillsaccept feed up to about 50 mm (2 in.) and produce a product in thesizerange of 3000 to 270 mm (–4 to –35 mesh).
