Usually, the grinding circuit contains at least two interconnected mills with material classifiers (e.g. cyclones) separating the fine material from the coarse (that then goes for regrinding). The process is energy intensive with power consumption of roughly 20 to 30 MW and feed throughputs of 2,500 to 3,000 t/hr. Process variables are mill ...
Ultra Fine Grinding - A Practical Alternative to Oxidative Treatment of Refractory Gold Ores S. Ellis Kalgoorlie Consolidated Gold Mines Kalgoorlie, WA. Abstract Since early 2001, Kalgoorlie Consolidated Gold Mines (KCGM) has successfully operated an ultra fine grinding (UFG) circuit to supplement its roaster capacity for the
Power Measurement: the only accurate way to measure mill power is to directly measure power or torque input to the shaft. Indirect measurements are inaccurate and will underestimate mill power (Nesset, J.E. et al, Assessing the Performance and Efficiency of Fine Grinding Technologies, 38th Annual Meeting of the CMP, Canada, January 2006).
