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 electronic waste, and other related copper and aluminum recycling industries.The internal structure is constructed with cutting-edge technology, utilizing a magnetic system composed of strong neodymium-iron-boron permanent magnets, featuring strong magnetic field, energy-saving, easy maintenance, and convenient use.Section II: Main Structure and Working Principle1. Main StructureThe machine is primarily composed of an external drum, eccentric roller, magnetic roller drive motor, reducer, idle roller, annular integrated belt, vibrating screen, and machine frame.2. Working PrincipleMaterial is fed from the vibrating screen to the magnetic roller via a belt conveyor. The internal magnetic roller rotates at high speed, causing conductors (non-ferrous metals) within the material to generate induced currents in a 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.III. Technical Parameters Dimensions are as actual measurements.

IV. Installation and Commissioning1. The magnetic separator is composed of parts such as the drive unit, drum, and vibration feeding device.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. Inspect the motor's operation and ensure the direction is correct.4. Check if the voltage is normal, insulation is good, and the magnetic separator is grounded.5. Check for any foreign objects that may hinder the roller's operation; only then should the motor be started.6. Adjust the magnetic system bias angle based on the iron removal effect to achieve the ideal iron removal performance.V. Operation ProceduresEnsure power connection to guarantee normal machine operation and prevent any alarm signals.Manual method1. Turn on the internal magnetic roller with the touch screen and rotate the roller speed button to gradually increase the speed of the roller2. Once the internal magnetic roller reaches the required speed, activate the belt-driven motor.3. Once the belt operates normally, start the vibration screen.4. Feed material only after the vibration screen has stabilized its operation.Automatic Mode1. Tap the touchscreen to automatically start2. Feed material only after the machine has automatically activated the internal magnetic roller, belt, and vibration screen.Once the equipment is turned on, the internal magnetic roller operates 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 that is opposite in direction to the original field, exerting a strong repulsive force on the non-ferrous metals, causing them to be instantaneously ejected from the material, thereby achieving the separation goal.Six: Precautions and Consumable Parts1. The reducer starts operation and should be re-lubricated after 400 hours; subsequent oil change intervals are approximately every 4000 hours.2. Sufficient lubricating oil should be maintained within the reducer housing, and regular inspections should be conducted.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 that the feet are securely and stably positioned to prevent equipment displacement, damage, and safety hazards.6. If abnormal phenomena are detected during operation, such as smoking, strange odors, or abnormal working current and voltage, 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 inspect 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 lubricant.
