See the main article for detailed explanation of the basis and limitations of mill power draw models.

Summary

Mill power draw models are used to predict how much power will be consumed by a particular type of mill, mill geometry and set of mill operating conditions. This power is transferred to the ore and used to predict the throughput when combined with the specific energy consumption models.

Power at the mill shell

The mill power draw models used in SAGMILLING.COM all reference power as drawn at the mill shell. Most surveys report power values as they are measured in the plant distributed control system (DCS), which is usually relative to the motor input power. Refer to the Measurement of power article for description of how to convert DCS indicated power to mill power at the shell.
