Reported by 16 that each grain size has an optimum ball size. energy wastage and drop in throughput are the consequence of deviation from optimum conditions 17, 18, 19. the critical grinding speed v c of a ball mill in rpm is given by 20 as 3 42. d d v c 1 where d is the mill diameter and d is the ball diameter. the ...

7depending on the mill size the sag mills draws between 2 mw and 17 mw. the product from the sag mill is further reduced in size using pebble crushers and ball mills. hence, typical gold or copper ore requires between 2.0 and 7.5 kwh per ton of energy to reduce the particle size.

Energy-savings in shandong province are listed in table es-1. thirteen cost-effective electricity-saving technologies and measures that have not been fully adopted are all related to improving the efficiency of motors and fans, fuel preparation, and finish grinding. in addition, two finish grinding options replacing a ball mill with a vertic.

Energy balance data is related to mill temperature where the latter is believed to be a primary indicator of in-mill process dynamics 21, 12. it is a known fact that the biggest part of energy introduced in a ball mill is converted into heat, with only about 3 - 5 of this energy being used to grind the ore to the required fineness.
