Primary grinding consumes a significant percentage of plant operating costs. It has a significant effect on the performance of downstream process, such as flotation.
Effective SAG mill control will maximise throughput, minimise damage to mill internals (liners and lifters) and contribute significantly to achieving maximum recovery in flotation. Well designed and implemented SAG control will payback in weeks not years. SAG mill control is essentially the stabilisation of mill load (and/or power) and density which can be implemented successfully and very cost-effectively on most modern PLC or DCS platforms.
The application of advanced regulatory control is a MIPAC speciality which we have applied productively in SAG milling and other mineral beneficiation processes.
