Before operation

Equipment inspection

• Appearance and StructureCarefully inspect the equipment casing for any damage or cracks, ensure that all components are securely connected, and check for loose fastening bolts. For example, if the fixed bracket of the magnetic roller is found to be loose, the magnetic roller may shift during operation, affecting the separation effect and even damaging the equipment.
• Electrical systemCheck if the power cord is intact, if there is any damage or aging, and if the plug and socket are in good contact. Use a multimeter to check the insulation resistance of electrical components to ensure compliance with safety standards and prevent electrical leakage accidents.
• 磁性部件Check whether the magnetic strength of magnetic components (such as magnetic rollers and magnetic bars) is normal, and whether there are impurities such as adsorbed iron filings on the surface that affect magnetism. The performance of magnetic components can be judged through simple adsorption tests, such as using small iron nails to approach the magnetic components and observe the adsorption situation.

Material preparation

• Material CharacteristicsUnderstand the composition, particle size, proportion of magnetic substances, and other characteristics of the material to be processed. For example, for materials with larger particle sizes, it may be necessary to adjust the feeding speed and separation gap of the equipment; For materials with a high proportion of magnetic substances, it may be necessary to increase the cleaning frequency of the equipment.
• preprocessingAccording to the characteristics of the material, necessary pretreatment should be carried out, such as filtering out large impurities and adjusting the humidity of the material. If the material contains a large amount of large particle impurities, it may block the feed inlet or separation channel of the equipment, affecting the normal operation of the equipment.

Parameter Settings

• feeding speedReasonably set the feeding speed based on the characteristics and separation requirements of the material. Excessive feeding speed can cause materials to stay in the equipment for too short a time, resulting in incomplete separation; If the feeding speed is too slow, it will reduce production efficiency. The optimal feeding speed can be determined through experimentation.
• Separation gapAdjust the separation gap between magnetic and non-magnetic components to adapt to the particle size and separation requirements of the material. The separation gap is too large, and magnetic substances may not be effectively separated; If the separation gap is too small, it may cause material blockage.
• magnetic field strengthAdjust the magnetic field strength of the device based on the magnetic strength of the magnetic substance. For substances with weak magnetism, it is necessary to increase the magnetic field strength appropriately to improve the separation effect.

In progress

safety protection

• personal protectionOperators must wear protective equipment such as gloves, goggles, etc. Protective gloves can prevent hands from being scratched by materials or pinched by magnetic components, while goggles can prevent materials from splashing and injuring the eyes.
• safety distanceDuring the operation of the equipment, operators should maintain a safe distance and avoid getting their body parts close to the rotating and magnetic parts of the equipment. Especially during equipment cleaning and maintenance, ensure that the equipment has stopped running and the power is cut off.
• Warning signSet up clear warning signs around the equipment to remind operators to pay attention to safety. For example, setting up signs such as "High Voltage Danger" and "Do Not Touch".

operation monitoring

• Separation effectRegularly inspect the separated materials and observe the separation of magnetic substances. If a decrease in separation efficiency is found, the cause should be analyzed in a timely manner and equipment parameters should be adjusted. For example, it may be due to weakened magnetic properties of magnetic components or inappropriate separation gaps.
• Equipment operating statusPay attention to the sound and vibration of the equipment during operation. If there are any abnormalities, stop the machine immediately for inspection. For example, abnormal noise emitted by equipment may be caused by bearing damage, transmission component failure, and other reasons.
• temperature monitoringMonitor the operating temperature of the equipment, especially the temperature of magnetic components and electrical components. If the temperature is too high, it may cause problems such as weakened magnetic properties of magnetic components and damage to electrical components. Temperature sensors can be installed to monitor device temperature in real-time.

after operation

Equipment cleaning

• 磁性部件清理Timely clean the magnetic substances adsorbed on the magnetic components to prevent excessive accumulation of magnetic substances from affecting the magnetic strength and separation effect. Special scraper or brush can be used to remove magnetic substances from magnetic components.
• Internal cleaning of equipmentClean up residual materials and impurities inside the equipment to maintain its cleanliness. Compressed air or a vacuum cleaner can be used for cleaning to avoid material accumulation inside the equipment, which can cause corrosion or blockage.
• External cleaning of equipmentWipe the equipment casing with a clean cloth to remove dust and stains, and keep the appearance of the equipment clean.

Equipment Maintenance

• Lubrication and maintenanceAccording to the requirements of the equipment manual, lubricate and maintain the transmission components, bearings, etc. of the equipment. Regularly add lubricating oil or grease to reduce component wear and friction. For example, for bearings, an appropriate amount of lubricating grease can be added at regular intervals.
• Maintenance of magnetic componentsRegularly check the magnetic strength of magnetic components, and if magnetic weakening is found, promptly magnetize or replace the magnetic components. At the same time, rust prevention treatment is applied to magnetic components to extend their service life.
• Electrical system maintenanceRegularly check whether the connections of the electrical system are loose and whether the electrical components are working properly. If necessary, professional electricians can be hired to maintain and repair the electrical system.

Fault handling and recording

• Fault handlingIf the equipment malfunctions during operation, it should be stopped immediately and troubleshooting should be carried out according to the equipment manual or professional guidance. When dealing with faults, pay attention to safety and avoid causing secondary damage.
• Fault RecordDetailed records of fault symptoms, occurrence time, handling process, and results. These records can provide reference for future equipment maintenance and management, help analyze the causes of faults, take corresponding preventive measures, and avoid similar faults from happening again.
