Eddy current separator

Eddy current separation is an effective method for recovery of non-ferrous metals, which has the advantages of excellent separation effect, strong adaptability, reliable mechanical structure, light structure, strong repulsion (adjustable), high separation efficiency and large handling capacity. it can separate some non-ferrous metals from e-waste and is mainly used to separate non-ferrous metals such as copper and aluminum from mixed materials in e-waste recovery production line.
It can also be popularized and applied in the field of environmental protection, especially in the non-ferrous metal recycling industry.
Eddy current separation is a separation technology that makes use of different electrical conductivity of materials. Its separation principle is based on two important physical phenomena: an alternating magnetic field that changes at any time is always accompanied by an alternating electric field (the law of electromagnetic induction); a current-carrying conductor produces a magnetic field.
When the electronic waste containing non-magnetic conductor metals (such as lead, copper, zinc, etc.) passes through an alternating magnetic field at a certain speed, the induced eddy current will occur in the gold scraps of these non-magnetic conductors.
Because there is a relative velocity between the material flow and the magnetic field, there is a thrust to the metal sheet and block that produce eddy current.
By using this principle, some non-ferrous metals can be separated from the mixture flow.
The thrust acting on the metal depends on the size, shape and degree of irregularity of the metal piece.
The direction of the separation thrust is 90 degrees with the direction of the magnetic field and the direction of the material flow.

How it works:
The non-ferrous metal separator is designed based on the principle that the conductor can produce induced current.
When the machine is working, when the metal enters the division area, it will induce an electric current inside the metal. The magnetic field generated by this current is opposite to the direction of the original magnetic field, and there is a mutually exclusive force. This repulsive force can throw the metal block forward to achieve the purpose of separation.
