TECHNICAL NOTES 8 GRINDING R. P. King - Mineral Tech

 · The ball mill ball ratio should be judged according to the effective length of the mill, whether it is equipped with roller press, feed size, lining material and structure, and the number of rotation speed. After installing the ball mill, ball mill size gears need to be meshed and the amount of processing is also gradually increasing. The basic parameters used in ball mill design (power calculations), rod mill or any tumbling mill sizing are; material to be ground, characteristics, Bond Work Index, bulk density, specific density, desired mill tonnage capacity DTPH, operating % solids or pulp density, feed size as F80 and maximum ‘chunk size’, product size as P80 and maximum and finally the type of circuit open/closed ... · The grinding operation in a ball mill is a capital- and energy intensive process. Hence, a marginal improvement in the efficiency of mill operation will be of immense economic benefit to the industry (Datta and Rajamani, 2002). Ball milling has been the …
