PROCESS DIAGNOSTIC STUDIES FOR CEMENT MILL

2013-3-13 · M/s Holderbank Engineering, Canada has developed a control strategy for ball mills which can maintain a mill production near optimum, with little operator intervention. The main principle of the concept is that maximum production is obtained from a ball mill when the mill motor power is at a maximum and consequently the specific energy consumption is at minimum. The maximum power point is dependent upon the feed material characteristics, mill
