What is it: a system that can vary the electric motors power supply frequency. The system usually allows to vary the frequency from 20 to 70 Hz.

What is it used for: to vary electric motor revs. In this way, it is possible to regulate the quantity of material being produced if installed on the feeders (also vibrators). In the case of the vertical axis hammer mills the particle size curve can be varied and controlled and energy consumption reduced.

Advantages:
Automatic regulation of material flow rate
Increase, optimisation and control of production
Lower energy consumption
Reduction of wear components
