FL highlights potential throughput increase in SAG ...
"Many SAG mill liner designs perform very well in their objective to achieve the desired particle size and protect the mill structure. However, no matter how well a mill is operated, and no matter how well a liner design performs, a mill is only as good as its ability to discharge the slurry out of the mill.
In many grinding plants mills which have metallic or rubber liners suffer from bolt breakage. Our technicians come across broken mill bolts at many sites around the world, to the operators of the mills it is an almost normal occurrence, but if you have breaking bolts there is an underlying problem which needs to be fixed.
