Specific Energy Consumption is the most common way of describing how much energy is used by grinding, and is the basis of the throughput estimations in SAGMILLING.COM. It is usually expressed as kWh/t (kilowatt-hours per tonne). Models of this type generally assume a standard particle size distribution and use a single position on that particle size distribution to characterize the entire
