A SAG mill operates with a 10000 hp motor. Typical power draw is 80% of maximum. The 80% passing feed size to the mill is 5 inches and the mill discharge has an 80% passing size of 2.1mm. How do i calculate the Operating Work Index for this mill if the feed tonnage rate is 1200t/h?

Try this SAG Mill Operating Work Index Calculator http://www.911metallurgist.com/blog/formula-to-calculate-a-mill-operating-work-index-equation

It looks like 6.6 kWh/ton
