In the past when primary secondary and tertiary crushers fed material directly to large ball mills the energy efficiency of the concentrator was determined for the most part by the ball mill operation whereas now the energy efficiency of a plant often rests largely on the SAG mill operation
The technique utilises metalliferous grain induced selective breakage and size based screening to separate the feed ore by grade Four copper gold ore samples were tested to demonstrate the viability of this technique Potential applications of the HVP pre concentration technique to treat AG SAG mill pebbles and AG SAG mill feed are discussed
SAG Mill Control SAG mills can be optimized for maximum ore throughput or maximum grinding energy efficiency In both cases precise control of the mill filling percentage is critical Wills and Napier Munn 2006 Maintaining constant mill weight as indicated by bearing pressure is one approach to stabilize the mill

Abstract One very important charge condition that can produce a catastrophic failure during the starting of grinding mills is the compacting of the load inside the mill especially after long downtimes This condition is usually named frozen load and the load remains locked to the mill shell and after a half turn drops damaging the mill body and bearings
The Selection and Design of Mill Liners Malcolm Powell Ian Smit Mines WA 36ft SAG mill the number of Outer Head Liners was reduced from 36 to 18 pieces and in doing so reduced the time to replace them by 9 hours at a cost downtime saving of about U 25 000 per hour In this case the liners sections are 3 5 t each

To prevent spillage and overload the control scheme must allow the ball mill circuit to accept almost any amount of feed rate without overload At high feed rates this will compromise the grind size so the SAG mill feed rate limits must be managed to ensure the right grind size versus throughput tradeoff is
At the Lihir Gold Mine the concentrator plant was utilizing SAG mill s bearing pressure to calculate load measurement for their mill Following a series of SAG mill overload events that caused significant milling downtime the mill operators and metallurgists lost confidence in the repeatability and accuracy of the load measurements
