Self-Clean Chute Magnet

The MPI Self-Clean Chute Magnet is engineered for continuous, automated removal of ferrous contaminants in vertical or near-vertical chute applications. Featuring robust Ceramic 8 permanent magnets, this system effectively captures and holds metal debris, thereby ensuring product purity and safeguarding downstream machinery. Its pneumatically operated self-cleaning mechanism, managed by a timer or sensor, eliminates the necessity for manual maintenance while allowing for uninterrupted material flow.

Designed for installation in vertical or near-vertical chutes, MPI Self-Clean Chute Magnets intercept and retain ferrous contaminants as material moves through the chute. The magnetic field generated by the magnets attracts and secures metal objects. The self-cleaning mechanism regularly removes the captured contaminants without halting the material flow. This automated cleaning process, governed by a timer or sensor, ensures reliable operation while minimizing manual upkeep.

Product flow occurs between two large permanent plate magnets positioned on either side of the chute. A center diverter channels the product toward the working surfaces of these plate magnets, which are stepped to reduce tramp metal "wash-off." Contaminants are collected under the stepped design of the plate magnet, and the cleaning shell or operator safely removes any trapped metal to a disposal area outside the chute.

As the material advances through the chute, it passes between two large, high-strength permanent plate magnets that generate a powerful magnetic field, attracting and securely holding ferrous contaminants such as screws, bolts, metal shavings, and other debris.

The center diverter enhances the separation process by directing the product stream toward the magnets’ active surfaces. The stepped design of the plate magnets prevents the re-release of captured metal, ensuring contaminants remain retained until they are automatically expelled.

The self-cleaning mechanism operates continuously without interrupting the material flow, following these essential steps:

1. Detection & Retention – Ferrous contaminants are drawn to and held by the plate magnets as the product flows past.

2. Pneumatic Cleaning Cycle Initiation – A programmed pneumatic cleaning shell activates at predetermined intervals or upon sensor detection.

3. Metal Contaminant Removal – The cleaning shell retracts automatically, dislodging and transporting trapped tramp metal to a designated disposal area outside the chute.

4. Magnet Reset for Continuous Operation – The system quickly resumes its active state, ensuring smooth material processing.

By automating the cleaning procedure, the MPI Self-Clean Chute Magnet minimizes downtime, reduces manual intervention, and guarantees consistent and efficient metal removal. This leads to improved product quality, enhanced operational efficiency, and superior protection of equipment in industrial processing environments.
