Eddy current separators can usually automatically separate non-metallic materials from non-ferrous metals.
The eddy current sorting machine uses the principle of induction current. When the eddy current sorting equipment is working, if there is metal entering, a current will be induced inside. The magnetic field generated by this current is opposite to the original magnetic field, and there is a mutual repulsive force. The repulsive force can throw the non-ferrous metal body forward to achieve the purpose of automatic separation.
Before entering the sorting process, it must go through a screening process to ensure that the particle size of the material is within a certain range, so that the throwing distance of the material will be roughly equal. If the particle size is very different, it will form a phenomenon that small particle size materials enter the non-metallic discharge hopper.
When the feeding speed is constant, the rotation speed of the belt affects the distribution density of the material on the belt. When the belt speed increases, the density of material distribution decreases gradually, so that the interaction between particles in the separation area gradually weakens, which is beneficial to separation.
On the other hand, since the rotating speed of the rotor remains constant, when the belt speed increases, the time for the materials to be sorted to stay in the sorting area becomes shorter. When the belt speed increases to a certain level, the interaction between the metal particles and the magnetic field is too late, thus reducing the separation efficiency.
Using industries: plastics, glass, electronic waste, urban solid waste, car crushing and recycling, recycling of mixed materials, recycling of industrial slag tailings, recycling of urban woody waste, sorting of various metal mixtures.
