Self-Cleaning Plate Housing Magnet

       After the material enters the equipment through a pipeline, the built-in plate magnet generates a stable, high-intensity magnetic field. As the material passes through this field, ferromagnetic contaminants are rapidly adsorbed onto the surface of the magnet, while the cleaned material continues to flow to the next process. The device can automatically activate its cleaning mechanism according to a preset schedule, using either an electric motor or a pneumatic actuator to scrape off and discharge the captured iron impurities, thereby achieving continuous online ferrous contaminant removal without frequent shutdowns for manual cleaning.

Features and Advantages

• Automatic Iron Removal: Supports timed or continuous automatic cleaning, reducing manual maintenance and enhancing production continuity.
• High-Intensity Magnetic Separation: Employs high-performance NdFeB magnets with a stable magnetic field, effectively capturing fine iron particles and weakly magnetic impurities.
• Continuous Operation: Iron removal is performed without stopping the machine, meeting the continuous-operation requirements of automated production lines.
• Anti-Clogging Design: A special flow-guidance and magnet arrangement minimizes material accumulation, bridging, and blockages.
• Sealed, Contamination‑Proof Construction: Fully enclosed stainless‑steel structure prevents dust leakage and secondary contamination of materials.
• Low-Energy Operation: The permanent-magnet system requires no electrical excitation; only the automatic cleaning mechanism consumes a small amount of power.
• Durable and Reliable: The material-contact parts are made of SUS304 or 316L stainless steel, offering corrosion resistance, easy cleaning, and long service life.
