Getting the most from Milling Circuit
Since grinding is by far the most energy-intensive process in mining, it provides tremendous opportunities for net energy efficiency improvements. Grinding circuit improvements can be based on various themes such as the optimisation of mill feed size, mill liner design, process control, grind size, grinding media and classification. We should first define our objectives – what needs to be optimised?
