The large critical size pebbles are useful for maintaining optimal filling in SAG mill at times when there is shortage of competent pebbles (Loveday, 2001, Powell et al., 2015b). In situations like this, the SAG mill control should take priority and it is neccessary to have sufficient pebble storage capacity, to be able to supply both circuits.

SAG Mill Liner

Based on experience, mill liner designs have moved toward more open shell lifter volumetric capacity and a grate design to facilitate maximizing both pebblecrushing circuit utilization and SAG mill capacity. Mill throughput is maximized with shell lifters between ratios of :1 and :1.

Aug 18, 2004· Good point on the roller sag. My screen is 96" wide, so it is a pretty long roller, and I have it mounted only from the ends. A better solution for me may be to add another mount point in the middle of the span to avoid the sag. I knew I was coming to the right place to talk to some creative problem solvers. I'll try that first.

The capacity of the SAG mill was not fully utilized, as the actual operating power draw was only 3358 kW. This meant it was only operating at 56% of its maximum power, providing large room for improvement. The load on the ball mill was on the high side, with an actual operating power draw of 5300 kW, meaning it was operating at 90% of its maximum power.
