## The power consumption calculation of a ball drum mill

Ball drum mills area commonplace in grinding offerrous and nonferrous metals, and a cement production in the world A significant shortcoming of these mills is high specific energy consumption onThe consumption of energy in the process, especially in the process where the large part of it is energy required for grinding, should be kept at the lowest possible level The agitator shaft speed significantly influences the energy consumption of the ball mill Therefore, the agitator should be run at lowest possible speed to meet the degree of particle size reduction that is needed (or any otherThe effect of processing parameters on energyGrinding media consisting of steel balls, with typical diameters from 25 to 75 mm, is already present in the mill along with any rock that has not yet overflowed through the discharge end Typical power consumption for a 5m diameter by 7mlong ball mill is between 25 and 35 MWCharge behaviour and power consumption in ball mills

## Energy Use of Fine Grinding in Mineral Processing

## Breaking Down Energy Consumption in Industry Grinding Mills

Breaking Down Energy Consumption in Industry Grinding Mills J Bouchard (1), G LeBlanc (2), M Levesque (3), P Radziszewski (4) and D GeorgesFilteau (1) 49th Annual Canadian Minerals Processors Conference, Ottawa, Canada, 2017 ABSTRACT Grinding mills are infamous for their extremely low energy efficiencycompared to the power used by a semiautogenous mill and a ball mill in a primary grinding circuit; a ball mill can have an installed power of up to 15 MW, while installed power for a SAG mill can go up to 25 MW However, the energy used for ﬁne grinding is still signiﬁcant Moreover, as this paper seeks to demonEnergy Use of Fine Grinding in Mineral ProcessingBall Mills an overview ScienceDirect Topics They have lower specific energy consumption than ball mills and the separator, as in raw mills, is integral with the mill body In the Loesche mill, Fig 223 , 16 two pairs of rollers are used In each pair the first, smaller diameter, roller stabilises the bed prior to grindingball consumption in grinding mills

## Comparison of energy efficiency between ball mills and

The work using a vertical shaft stirred mill compared with Bond ball mill, both operated in closed circuit with a classifier, demonstrated a clear trend that on average 30% energy saving can be expected by using the stirred mill to replace ball mill for coarse grinding from a top particle size 335 mm to P 80 less than 100 μmFine grinding, to P80 sizes as low as 7 μm, is becoming increasingly important as mines treat ores with smaller liberation sizes This grinding is typically done using stirred mills such as the Isamill or Stirred Media Detritor While fine grinding consumes less energy than primary grinding, it can still account for a substantial part of a mill’s energy budget Overall energy use and mediaEnergy Use of Fine Grinding in Mineral Processingconsumption energy in grinding ball mills lmidfr consumption energy in grinding ball mills Best energy consumptionInternational Cement Review Grinding energy was approximately 50 per cent of the ball mill and the drying capabilities allowed direct processing of materials of up to 20 per cent moisture content The main energy issue was the high power consumption of mill fans with pressureconsumption and investmentconsumption energy in grinding
