(PDF) The Influence of Liner Wear on Milling Efficiency
The need to improve and sustain the capacities of grinding mills over a longer time while mitigating the operating costs, is of prime concern in the milling industry todayGrinding and processing WEG offers the most reliable and efficient solutions for milling plants for ferrous and nonferrous products with their experience of mill drive systems In the heart of a processing plant, the ball and SAG mills must be driven by solutions that adapt to the characteristics of the minerals in line with the whole processMining Grinding and Processing WEGSAG Mill Discharge Controlling the feed and discharge of a mill is mostly a stabilisation exercise – you need to be able to quickly and accurately control the mill feed rate If the mill feed setpoint is changed, then the actual feed rate needs to stabilise at the new target in a short period of time The feed rate setpoint can then be tied Throughput optimisation in milling circuits
