the ball mill had an average production rate of 190tph with a specific electrical energy consumption of 35.5kWh/t. Its operational issues included: • oversized limestone • worn-out lifting liners with liner thickness decreasing from 80 to 20mm • low-quality media. Following evaluation and as part of the optimisation of the ball mill, the ...
