1、 Daily basic maintenance

1. Clean the surface of the equipment
   • Clean the dust, oil stains, and chips from the equipment casing, operation panel, and surrounding environment to prevent impurities from entering the interior of the equipment.
   • Regularly clean the slag discharge plate and slag discharge outlet of the magnetic separator to ensure smooth discharge of impurities and avoid blockage.
2. Check the equipment status
   • Before starting, check if the power switch, cables, and wiring are intact to avoid poor contact or leakage risks.
   • Observe whether there is wear, deformation, or material accumulation on components such as magnetic blocks, magnetic wheels, and conveyor belts, and promptly repair or replace damaged parts.
   • Check the tension of the conveyor belt to prevent deviation or slippage; Clean the surface debris of the conveyor belt to ensure smooth operation.
3. Lubricate transmission components
   • Regularly add lubricants to transmission components such as bearings, gears, and chains to reduce friction and wear.
   • Check whether the lubrication system oil circuit is unobstructed and whether the oil quality is qualified. If the oil quality deteriorates, it should be replaced in a timely manner.

2、 Regular deep maintenance

1. Maintenance of magnetic components
   • Magnetic field strength detectionRegularly measure the magnetic field strength of magnets using instruments such as Gaussian meters to ensure compliance with equipment design requirements.
   • Clean the surface of the magnetWipe the magnet with a soft cleaning cloth and appropriate cleaning agent to remove dirt and impurities, and maintain good magnetic field distribution.
   • Avoid damage to magnetsTo prevent the permanent magnet from being subjected to severe impact, high temperature, or strong magnetic field interference, and to prevent a decrease in magnetic performance.
2. Equipment component inspection and replacement
   • Monthly inspectionClean the equipment, check the wear of magnetic blocks and magnetic wheels, and replace damaged parts in a timely manner.
   • quarterly inspectionConduct a detailed inspection of the electromagnetic coil to ensure that the insulation material is intact; Check the performance of the control module, perform software updates and calibration.
   • Maintenance every six monthsPerform comprehensive maintenance on the equipment, including tightening connecting bolts and nuts, adjusting chain tension, etc.
   • Annual major repairsConduct comprehensive maintenance such as oil change, replacement of vulnerable parts, electrical testing, and performance testing.
3. Cooling system maintenance (if any)
   • Check whether the cooling fan and cooling water pipeline are blocked to ensure the normal operation of the cooling system and prevent equipment overheating.

3、 Maintenance under special working conditions

1. Long term disuse pre-treatment
   • Clean up impurities inside the equipment to prevent accumulation and freezing; Adjust the tightness of components such as chains and apply oil to prevent rusting.
   • Cut off the power, turn off the main switch, put on a protective cover, and store in a dry and ventilated place.
2. Check before reactivation
   • Check if the equipment accessories are intact and replace them promptly if there are any problems. It is recommended to contact the original manufacturer to obtain compatible accessories.
   • Confirm that the installation position of the equipment has not been shifted or deformed to avoid affecting the separation effect.
3. Environmental adaptability adjustment
   • Avoid prolonged operation of equipment in damp, dusty, or corrosive environments, and take protective measures if necessary.
   • Adjust operating parameters (such as conveyor belt speed) based on the iron content of the material to ensure separation efficiency.
   • When handling high-temperature materials, confirm the equipment's high-temperature resistance and prevent demagnetization of magnets.

4、 Operating standards and safety

1. Pre-operation preparation
   • Familiar with equipment operation procedures, ensure the safety of the surrounding environment of the equipment, and avoid unrelated personnel from approaching.
   • When starting, first turn on the conveyor belt and run it smoothly before starting the magnetic separator. Observe for any abnormal sounds or vibrations.
2. Monitoring during operation
   • Pay attention to the magnetic attraction to ensure effective adsorption of ferromagnetic impurities; Monitor the speed of the conveyor belt to prevent deviation or slippage.
   • Check the bearing temperature (not exceeding 40 ℃ of ambient temperature, up to 70 ℃), and observe the iron outlet to prevent blockage.
3. Shutdown operation
   • Stop feeding first, wait for all materials to pass through before stopping the magnetic separator, and finally stop the conveyor belt.
   • Clean the surface and surrounding impurities and dust of the equipment after shutdown to maintain a clean environment.
4. safety protection
   • It is strictly prohibited to approach rotating parts and adsorption areas during operation, and it is forbidden to reach out or use tools to take iron.
   • During maintenance or cleaning, cut off the power supply and hang a "Do Not Close" warning sign. Operators should wear protective equipment such as safety helmets and gloves.

5、 Recording and Training

1. Maintenance Record
   • Regularly record the operation and maintenance of equipment, including information on fault symptoms, causes, repair processes, and replacement parts.
   • By recording and tracking issues, potential faults can be identified in advance and maintenance plans can be optimized.
2. Operator training
   • Provide training to operators on equipment working principles, operating procedures, and fault handling to improve equipment operational efficiency.
   • Emphasize safety regulations and ensure that operators are familiar with emergency response measures.
