Eddy current sorting is an effective method for non-ferrous metalsRecycling methods. It has the advantages of excellent sorting effect, strong adaptability, reliable mechanical structure, light structural weight, strong repulsive force (adjustable), high sorting efficiency, and large processing capacity. It can separate some non-ferrous metals from electronic waste and is mainly used in electronic waste recycling production lines to sort non-ferrous metals such as copper and aluminum from mixed materials. It can also be promoted and applied in the field of environmental protection, especially in the non-ferrous metal recycling industry.

When electronic waste containing non-magnetic conductive metals such as lead, copper, zinc, etc. passes through an alternating magnetic field at a certain speed, induced eddy currents will be generated in these non-magnetic conductive metal shavings. Due to the relative velocity between the material flow and the magnetic field, there is a thrust on the metal sheets and blocks that generate eddy currents. This principle can be used to separate some non-ferrous metals from the mixture stream. The thrust acting on the metal depends on the size, shape, and irregularity of the metal block. The direction of thrust separation is 90 degrees with respect to the direction of magnetic field and material flow.

1Regularly inspect the connecting bolts and related important structures of the eddy current sorting machine to see if there is rust or looseness in the connecting parts.

2For the installation of eddy current sorting machines, it is necessary to comply with the prescribed requirements. Based on the degree of environmental pollution caused by the use of eddy current sorting machines, a comprehensive and effective cleaning and maintenance plan should be developed to ensure that the equipment performance can be maintained in an optimal state and to cope with each sorting operation.

3The basic cleaning of the eddy current sorting machine includes the cleaning and maintenance of the overall appearance and distribution structure. With appropriate cleaning agents, it assists everyone in thoroughly and effectively removing stubborn dirt.

4Based on the usage and operating environment of the eddy current sorting machine, regularly inspect the wear of related connectors and components, and replace and repair them in a timely and effective manner according to the degree of wear.

5Every maintenance and basic cleaning work of the eddy current sorting machine needs to be recorded properly, so that it can be easily queried in the later stage. If there is a fault problem, professional maintenance personnel should be notified to come and handle it. Do not disassemble and inspect it yourself, otherwise it may lead to larger faults.

6It can be observed that the working intensity of eddy current sorting machines is very high, usually operating continuously without stopping. During the operation of such equipment, if abnormal phenomena or noise problems occur, the operation must be stopped according to the prescribed steps, and the abnormal phenomena must be eliminated before restarting.
