////High Tension Electrostatic Separation Machine

What is Electrostatic Separator?
High tension electrostatic separator, also called high voltage electrostatic separator, is a device for separating all kinds of conductors and non conductors; metals and non-metals. Inside the electrostatic separator, surrounding air layer will produce ionization because of high tension electrostatic generator, then the metals and plastic materials (conductors and non conductors) are separated from raw materials according to the different permittivity.

Nowadays, green environmental protection has become a global topic in the world. To save energy and prevent the pollution caused by the waste, high tension electrostatic separation equipment can turn these waste into treasure. Our high voltage electrostatic separator has the best separation effects, which can reach about 99%. After separation, the impurities are less than 1%, and the properties of raw materials are not changed and do not affect the recycling. According to the material properties and output, our company can manufacture single drum, double drum and four drum type electrostatic separation machine.

Main Features of Electrostatic Separator:
●No secondary pollution. Our equipment doesn’t need to use chemicals to dissolve the waste, and has no pollution to the environment.
●Wide adaptability. It not only separate all kinds of mixtures of metal and plastic, but separate aluminum-plastic, printed circuit board, PET, PVC, PP materials.
●High separation rate. High voltage electrostatic separator can separate about 99% of gold, copper, aluminum and other metals from the waste.
●Energy saving, low noise and large output. Output of complete set of   equipment can reach 1 ton/h.
●In addition to all of the above, our electrostatic separation equipment also have other advantages of automatic operation, stable performance, small floor space, etc.

Working Principle of High Voltage Electrostatic Separator
In the compound electric-field of combined with high voltage corona and high voltage electrostatic; with the function of electric power and mechanical force, high voltage electrostatic separator completes the separation process through the different conductivity of materials.

Mixtures of conductor and non-conductor, metal and non-metal will be transferred to roller from the feeding device after crushing. Accompanied with the rotation of roller, materials enter into the corona electric field between the high pressure electrode and grounding electrode. For one thing, when good conductivity particles contact with the surface of grounding electrode, electric charge of conductive metal or conductor particles will be delivered by the roller electrode quickly. Under the action of the centrifugal force and gravity produced by the rotating roller, conductor particles will depart from the roller electrode and fall into the conductor hopper.

For another, non-conductor can’t pass the electric charge when contacting with roller because of weak electrical conductivity. As the opposite charges attract each other, non-conductors are adsorbed on the surface of the roller. They will be transferred to the back of roller and swept by roller brush  then drop into the non-conductor hopper.
