High Voltage Electrostatic Separator

XDF-φ250×200 High tension electric Separator is mainly used for the separation of Conductor minerals and Non-conductor minerals. It is also used for the classification of the same material instead of screening. It also could be used for grain processing and some part of seed separation.

3.Working Principle:
When the material is took into the high voltage electric field that is effected by the corona electrode and polarity by rotating drum, the material is impacted by all kinds of electric power (including coulomb force, non electric field force and Interface suction), centrifugal force, gravity. Because of the difference of electrical property of the different material, the difference of the stress state result in the difference of dropping track, which achieves the separation aim.
In the effect of the high voltage electric field, the load carrying behavior of the Conductor and Non-conductor material: After the Conductor material absorbs the electric charge, and it will be taken away. Under the effect of centrifugal force and gravity, it drops down along the drum rotation direction; Because of the bad electrical conductivity of the non-conductor material, it can not be quickly taken away after it absorbs the electric charge in the high voltage electric field, it will be generated interface suction force with the drum face. This force is bigger than the join forces of centrifugal force and gravity. So the non-conductor material is sucked tightly on the drum until it is taken down by the brush. The material between the non-conductor material and conductor material drops in the middle, it is called neutral material.
