Electrostatic separator is mainly made up of high-voltage electrostatic generator, frame, insulation board, conveyor belt, driving wheel, rotating wheel, recycling board, discharge electrode and metal protective net. It works on the principle of corona discharge, where two plates are placed close together and high voltage is applied. This high voltage is used to separate the ionized particles.
Materials processed by the electrostatic separation machine can be sorted two times in one machine. It ensures materials have high purity after separation. To satisfy your personal needs, we produce both single roller and twin roller electrostatic separator that will satisfy your wants forever.
Electrostatic separator is commonly used in recycling industry, such as aluminum-plastic waste, copper-plastic waste, printed circuit board.
Broad Spectrum of Application Areas of Electrostatic Separation Equipment:
☞ Metal particles and non-metallic particles
☞ Conductor and non-conductor
☞ Aluminum-plastic waste, copper-plastic waste, printed circuit board(PCB)
☞ Mineral separation, carbon content extraction
☞ Grinding wheel ash extract metal
Advantages of Electrostatic Separator
▼ Highly efficient, energy saving and environmental protection separation equipment.
▼ After having been experimentally studied and theoretically studied for many years, it has reached very good separation effect. The impurity after separation can be less than 1%, that is also to say, the separation efficiency can be up to 99%.
▼ Whether metal or plastic, material processed will be separated two-time in our electrostatic separator. Hence, compared with other separation machines, this high voltage electrostatic separator has higher separation efficiency.
▼ Feeding hopper is the key device for enhancing the purity of materials. Our electrostatic separator adopts frequency control technology, which can achieve the best separation effect.
▼ After running for some period of time, lot of dust produced in the internal components of machine will affect the separation efficiency. To prevent this from occurring, our electrostatic separator adopts dust-blowing device, which makes machine always maintain high separation efficiency.
▼ Stable high voltage power is essential for separation. Electrostatic separation equipment adopts automatic voltage regulating device specially that ensures the high voltage power is always stable. Hence, the influence of humidity and electricity peak on machine is greatly reduced.
▼ It is easy to operate, good flexibility, the system safe and stable operation. And it possesses the automatic discharge system to provide reliable security for operator.
Electrostatic Separation Process – How does Electrostatic Separation Work?
As an important part of the electrostatic separator, the high-voltage electrostatic field plays a key role in the material processing.
Firstly, high voltage produced by high-voltage electrostatic field will be discharged through the connecting grounded rotary roller, and the materials are transported to the surface of rotary roller evenly through feeding hopper.
Secondly, electric conductor materials convey the electric to underground by rotary roller, then will be thrown into the conductor’s feeding hopper with the inertia of rotary roller. However, non-conductors absorbed on the surface of rotary roller will sweep into the non-conductor’s feeding hopper with the help of brush because of low electrical conductivity.
Finally, some of conductors and non-conductors fall into the middle feeding hopper due to some conditions such as rotation speed, particle size. They will enter into the feeding hopper for separation again.
