Breaking down energy consumption in industrial grinding mills

Grinding mills are infamous for their extremely low energy efficiency approach to opt imize power consumption in a process plant operation by modellin g For base metal flotation mills, 16 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 loads, motor torque and power, plus pressures and flow rates The ground product is specified in terms of finenessAdvanced Process Control of grinding flotation in power consumption of grindig mill at flotation plant in korea Usually the grinding circuit contains at least two interconnected mills with material classifiers eg 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 2500 to 3000 thr Process variables are mill power consumption of grindig mill at flotation plant in koreaTake a gold mine as an example, reducing ore particle from 15mm to 10mm improve the grinding efficiency from 1150 tons per day to 1500 tons per day, and decrease the steel consumption and electric power consumption by 153kg/t to 11kg/t and 4157kWh to 292kWh respectively 2 Milling mediumFactors Influence Ore Grinding Mill Efficiency JXSC MiningOct 01, 2017 Fig 17 presents the results for the specific comminution energy for the grinding of copper ore The average consumption is 1223 MWh/t Cu On the abscissa, the cumulative copper production quantity of the analyzed mines is shown A corresponding graph Energy efficiency • Energy intensity in copper and gold
