Eddy Current Separator

I. ConceptA non-ferrous metal separator is a magnetic separation equipment used for continuously recovering copper, aluminum, zinc, and other non-ferrous metals in granular and lump form. It is suitable for selecting copper and aluminum from industrial waste, construction and demolition debris, as well as for the treatment of domestic waste and pollutants. It is also used in material handling during non-ferrous metal processing, the recovery of copper, aluminum, and zinc from shredded auto parts, the recycling of used electrical appliances, and other related copper and aluminum recycling industries.The internal structure is constructed with cutting-edge technology, utilizing a magnetic system composed of strong permanent magnet neodymium iron boron materials. It boasts features such as strong magnetic field, energy-saving, easy maintenance, and convenient use.Section 2: Main Structure and Working Principle1. Main StructureThis machine is primarily composed of an external drum, eccentric roller, magnetic roller drive motor, reducer, idler roller, annular integrated belt, vibration screen, and frame.2. Working PrincipleMaterial is fed from the self-vibrating screen, transported along a belt to the magnetic roller. The internal magnetic roller rotates at high speed. Conductors (non-ferrous metals) within the material generate induced currents in the high-frequency alternating magnetic field. This current produces a magnetic field opposite in direction to the original field, exerting a strong repulsive force on the non-ferrous metals, which are instantly ejected from the material, achieving the separation goal.Section 3: Partial Technical Specifications Dimensions are as actual measurements.

IV. Installation and Commissioning1. The magnetic separator is composed of parts such as the driving unit, drum, and vibration feeder.2. Magnetic separators should be installed on a level, sturdy concrete or steel foundation. Ensure the stability of the separator's support feet and even distribution of force to prevent frame deformation caused by uneven ground.3. Check if the motor is operating normally and if the direction is correct.4. Check if the voltage is normal, insulation is good, and the magnetic separator is grounded.5. Inspect for any foreign objects that may hinder the roller operation; only proceed with motor start-up after they are removed.6. Adjust the magnetic system bias angle based on iron removal performance to achieve the optimal iron removal effect.V. Operational ProceduresEnsure power is connected to guarantee normal machine operation and no alarms.Manual method1. Turn on the internal magnetic roller with a touch screen, then rotate the roller speed button to gradually increase the roller speed2. Once the internal roller reaches the required speed, start the belt-driven motor.3. Once the belt operates normally, start the vibration screen.4. Feed material only after the vibrating screen has stabilized in operation.Automatic Mode1. Tap the touchscreen to start automatically2. After the machine automatically activates the internal magnetic roller, belt, and vibration screen, feeding can then proceed.Upon equipment activation, the internal magnetic roller operates at high speed. Conductors (non-ferrous metals) within the material generate induced current in the high-frequency alternating magnetic field. This current produces a magnetic field opposite in direction to the original field, exerting a strong repulsive force on the non-ferrous metals, which are then instantaneously ejected from the material, achieving the separation goal.Section 6: Precautions and Consumable Parts1. The reducer should be serviced and have its lubricant changed after 400 hours of operation, with subsequent oil change intervals approximately every 4000 hours.2. Ensure sufficient lubricant is retained in the reducer housing and inspect it regularly.3. There are two oil nozzles at each end of the magnetic roller. Add high-speed grease daily during machine operation!4. Promptly repair or replace the belt if damage is found during use.5. Prior to equipment operation, ensure the machine feet are stable and even to prevent equipment misalignment, damage, and safety accidents.6. In the event of abnormal phenomena in the motor during operation, such as smoking, strange odors, or abnormal working current and voltage, the power should be immediately disconnected for inspection. Only after the cause is identified and the fault is eliminated can the motor be put back into operation.7. Once the equipment is up and running, regularly check for loose fasteners and tighten them if necessary.8. When rubber aging leads to reduced sealing function and minor oil leakage, replace the oil seal and replenish the lubricant.
