Working Principle

XFD-12 Lab Flotation Machine is mainly consist of the following parts: lifting mechanism, machine body, stator and impeller part, inverter and control system.

All the parts are connected to the vertical column. The main shaft is driven by the motor to rotate in clockwise direction. The rotation speed of the impeller is controlled by the inverter.
The main shaft is driven by the motor to move up and down through screw lift.
