A big majority of people is still using the old Bond equations without asking themselves: do 950 g/t or 1,100 g/t of steel consumption in the ball mills make sense? When we apply our experience from the last 20 years we see right away that steel consumption in the range of 1,000 g/t in a ball mill is not correct, and that is a fact...

SAG Ball consumption is “average” at 400 g/t while Ball Mill grinding media (3″ balls) usage in 550 g/t Yet, you add steel and nothing seems to happen, tonnage is not noticeably improved You need more tonnage and could actually use a larger/coarser transfer size from the SAG to Ball Mill...
