Specific Energy Consumption Models
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 assume a standard particle size distribution and use a single position on that particle size distribution to characterize the entire curve. The most common way to express this is the 80% passing size, which can be expressed as F80 (feed stream 80% passing size), P80 (product stream 80% passing size), or K80 (generic stream 80% passing size. Bond (1952)[1] describes the rationale for using a single 80% passing size and indicative of the whole size range.
