  1. Industry Leading Magnetic Performance:
    • High performance Hi-G rare earth neodymium magnetic circuit generates 5400 gauss on the surface of the drum resulting in the highest separation rates (optional)
  2. High Separation Rates:
    • 220 Degrees of magnet material around the surface of the drum increases magnetic field exposure for better separation rates and less good product carry over
    • Oversized drivetrain for exponential service factor for reliable long term performance
  3. Minimize Carryover:
    • Adjustable pant leg distribution system for fine tuning the drum separator to minimize carryover
  4. Adjustable Flow Rate:
    • Adjustable feed gate for fine tuning feed into the system to optimize magnetic separation for flow rates
  5. Hassle Free Maintenance:
    • Inspection doors for easy access into the drum for maintenance
    • Easy removal of drum from drive side access panel for service and maintenance without removing housing from line (required for abrasive products shell replacement)
  1. Reinforced Seals:
    • Fully sealed design features double sealed bearings with external shield and sealed magnetic drum design to prevent damage from product ingress
  2. Flexible Positioning:
    • Adjustable magnetic arc position for fine tuning drum performance
  3. Made in the USA:
    • American manufacturing

 

MPI -- Magnetic Products, Inc. When the product stream enters the drum magnet, the powerful permanent magnetic field reaches out and retains ferrous particles on the revolving shell. As the product stream flows by the shell, any non-ferrous product falls unhindered from the shell, while tramp iron particles are solidly retained and carried away from the product stream, out of the magnetic field, past a divider and deposited into a tramp metal collection container. These DSH-Series magnets are available in standard diameters
