Quick-Clean Suspended Electromagnet

MPI’s Quick-Clean Suspended Electromagnets are high-performance, oil-cooled magnetic separation systems designed to extract tramp iron—both large and small—from product streams conveyed on belts or vibratory beds. These units offer a powerful and efficient method of metal separation in material handling systems operating at speeds up to 250 feet per minute.

System Components & Setup

• Oil-Cooled Electromagnetic Plate Magnet
  The heart of the system is a durable, oil-filled electromagnetic coil enclosed in a steel housing. The oil cooling improves heat dissipation, allowing the magnet to maintain high field strength and operate continuously in demanding environments.
• Suspended Mounting Configuration
  The magnet is mounted above the conveyor or vibratory bed, suspended in a position where it can scan the entire product flow. It’s typically installed at a strategic point in the process line where tramp metal is most likely to be encountered and easily removed.
• Quick-Clean Access Design
  While the unit does not use a self-cleaning belt, its Quick-Clean configuration allows operators to easily access and clean the magnet face, minimizing downtime and maintenance labor.

Operational Process

• Magnetic Attraction of Tramp Metal
  As the product stream moves beneath the suspended magnet, the powerful electromagnetic field penetrates through the conveyed material, attracting and lifting ferrous tramp metal—including bolts, nuts, nails, tools, and fragments—from the burden.
• Tramp Metal Accumulation
  The attracted metal debris adheres to the magnet’s working face, accumulating across its surface. This collection continues until the magnet reaches a capacity threshold or during scheduled maintenance intervals.
• Manual Cleaning Process
  To remove accumulated tramp metal, the unit is de-energized (cutting the magnetic field), and the metal drops away from the magnet face. The open-access design of the Quick-Clean configuration allows operators to perform this task quickly and safely.

Installation Considerations

• Non-Magnetic Support Structure
  To ensure optimal magnetic performance, the unit should be suspended over non-magnetic conveyor components. Avoid placing it near steel idler rollers, pulleys, or support plates, as these components may become magnetized and interfere with separation efficiency.
• Accessibility for Maintenance
  The magnet should be installed in a location that offers safe and easy access for cleaning and inspection. This ensures that maintenance teams can routinely remove tramp iron and verify system performance with minimal disruption to production.
