The BMPE Laboratory Magnetic Roll Separator is designed to process materials using a 100 mm (4”) or 150 mm (6”) diameter roll cassette. Featuring a 200 mm wide magnetic zone, the unit is compatible with various magnetic roll configurations and utilizes high-strength neodymium magnets. Built with a durable stainless steel frame, the assembly includes an integrated hopper system and two stainless steel splitters.

Performance results from this laboratory unit scale directly to full-size commercial operations. Separation efficiency can be optimized by selecting the appropriate magnetic roll design, belt thickness, roll speed, splitter position, number of separation stages, and feed layer depth (i.e., unit capacity).

Material is fed evenly onto the separator belt via a frame-mounted vibratory feeder and carried over the specialized magnetic roll. As the feed material enters the magnetic field, magnetic and weakly magnetic particles are attracted to the roll. Depending on their magnetic susceptibility, particles behave in one of two ways:

• Strongly magnetic particles attach to the belt surface and drop off once they move past the magnetic field.
• Weakly magnetic particles are drawn toward the belt, altering their trajectory compared to non-magnetic particles as they are thrown from the rotating roll.

Designed for continuous operation, the separator features a variable speed drive system with closed-loop control to maintain consistent roll speeds, along with a digital RPM display.
