05/09/2015· Calculate Top Ball Size of Grinding Media FRED C. BOND Equation Method. Although it was developed nearly 50 years ago, Bond s method is still useful for calculating necessary mill sizes and power consumption for ball and rod mills. This paper discusses the basic development of the Bond method, the determination of the efficiency correction ...
13/02/2017· The power calculated on using equation 1, , relates to: 1) Rod milling a rod mill with a diameter of 2.44 meters, inside new liners, grinding wet in open circuit. 2) Ball milling a ball mill with a diameter of 2.44 meters, inside new liners, grinding wet in open circuit.

03/07/2017· Having selected the best ball size, it will be seen by referring to tables 27 and 28 that the preferable ball size usually gave the best capacity and efficiency. Also, the preferable ball size coincides closely with the best selective grinding, the main exception being the plus 10 mesh series in table 28.
22/12/2016· Ball mill grinding is one method of crushing ore to an appropriate size fraction. Specifically, ore is put into a large receptacle and then it rotates slowly around.
02/08/2013· Based on his work, this formula can be derived for ball diameter sizing and selection: Dm <= 6 * d^0.5 where Dm = the diameter of the single sized balls in mm.d = the diameter of the largest chunks of ore in the mill feed in mm.
31/01/2015· Ball size depends on initial size of charge and ranges from 10mm 150mm dia. For particular material and initial size the ball size must be optimized.
