Drum Separator

MPI’s Drum Separator is designed for efficient, continuous separation of ferrous contaminants from dry, free-flowing product streams. The system operates using a high-intensity permanent magnetic field housed within a rotating drum shell. Here's how the process works in detail:

As the material is introduced to the infeed area, it flows across the rotating drum's surface. A robust internal magnetic circuit generates a deep-reaching magnetic field that penetrates the product stream. As the drum turns, ferrous particles—such as tramp iron, steel fragments, and fine metal shavings—are immediately attracted to and held firmly against the rotating shell's surface.

The drum's rotation carries these captured ferrous contaminants away from the clean product stream, maintaining constant contact with the magnetic field to ensure no particles are lost or re-entrained. As the drum rotates, ferrous materials are transported past a strategically positioned divider. Once the drum surface moves out of the magnetic field’s influence, the magnetic hold is released, allowing the ferrous contaminants to drop off cleanly into a dedicated tramp metal discharge chute or collection bin.

Meanwhile, non-magnetic materials are unaffected by the magnetic field and continue flowing downstream, uninterrupted and contamination-free. This process ensures continuous operation without stopping for cleaning or batch processing, which significantly increases throughput and system efficiency.

The DSH-Series Drum Separators are available in a range of standard diameters and configurations to accommodate various throughput rates, material types, and installation environments. Whether integrated into existing process lines or installed as standalone units, MPI Drum
Separators offer reliable, automated ferrous
removal with minimal maintenance.
