Get Price### effect of speed on tumbling mill power drawn

The power consumption is usually determined by charge fill level, lifter height, lifter number, and mill speed. However, almost all of the classical theories for calculating the power consumption of ball mills disregard the effect of lifters and only focus on rotation rate, charge fill level, as well as size and shape of grinding media, thereby ...

Get Price### Power Factor

The power factor of an AC electric power system is defined as the ratio active (true or real) power to apparent power, where. Active (Real or True) Power is measured in watts (W) and is the power drawn by the electrical resistance of a system doing useful work; Apparent Power is measured in voltamperes (VA) and is the voltage on an AC system multiplied by all the current that flows in it.
