Depending on the type of mixing principles involved, their size, speed and agitator design, mixers will be more or less energy intensive. Free fall mixers which are using diffusivity as main mixing mechanism will typically have the smaller energy consumption, convective mixers will be higher while the most energy will be consumed by shear mixers.
The table below is the typical specific power consumptions for the usual types of powder mixers found in the industry.
