17yo Drum Magnet A Testament To Quality
A MAGNATTACK™ Self-Cleaning Rotating Drum Magnet served one of our valued clients with effective foreign metal contamination control for over 17 years - without the need for major repairs!
HOW DRUM MAGNETS WORK:Drum Magnets are typically installed in dry, free-flowing product lines, such as grain or animal feed, and are typically suited to high tonnage intakes. The product enters down through the top of the housing before coming into contact with a stainless steel Drum. This Drum rotates around the outside of a fixed magnet element. As the product flows over the Drum, ferrous tramp and other metal contaminants are captured by the magnet and held securely to the stainless steel surface. As the drum rotates, cleats sweep the ferrous debris through and out of the magnetic field to a discharge point - creating continuous self-cleaning separation. With metal contaminants safely removed, the good product falls freely to a separate discharge point and continues on through the process line. This self-cleaning operation ensures that a clean surface is presented to the product flow at all times. There is minimal risk of collected fragments being dislodged by oncoming product and reintroduced to the product flow. In addition, the clean magnet is able to exert full magnetic strength to the product flow at all times and, therefore, is not at risk of 'shorting out'. Shorting out can occur on manual-clean designs where large amounts of metal are adhered to the magnet (often a result of missed cleaning schedules), thus lowering the magnetic force on the surface of the magnet that can be applied to oncoming contaminants.
THE INITIAL SUPPLY:In the year 2000, MAGNATTACK™ Global supplied an RE80™ Rotating Self-Cleaning Drum Magnet to an Australian client. The Drum Magnet was designed to remove ferrous metal fragments from incoming product and also to protect other plant equipment from damage caused by metal pieces.

REPAIRS TO THE RE80™ DRUM MAGNET:Like all magnets which service abrasive and high-tonnage applications, repairs are to be expected. Minor repairs such as seal replacement and the fitment of self-greasing applicators took place prior to 2018. In February 2018, the Drum Magnet was returned to our New South Wales manufacturing facility for the first time, to undergo more advanced repairs. These repairs consisted of:
- Replacement of bearings,
- Replacement of seals,
- Repairs to housing,
- Repairs to internal magnets, and
- Repairs to internal shafts and support bar.
