The P (proportional) type decanter centrifuge is characterised by one electric motor, driven by an inverter, which transmits the movement to the screw and the bowl, thus allowing a direct variation of the bowl revs. in proportion to the screw.
In addition to the proportional variation, the screw rotation full can be generated by replacing the pulleys with others provided in the equipment.
The working principle of the decanter centrifuge is based on the specific weight difference of the solid-liquid substances to treat. The separation takes place in the bowl, which rotates at high speed and multiplies thousands of times the force of gravity. The screw’s function is to put out the solid, which deposits in the bowl.
