Bunting’s Electro Drum Magnets are heavy-duty magnetic separators suitable for applications in the automotive recycling industry as well as the aggregate, mining, and minerals industries. These heavy-duty magnetic separators are designed to separate and recover large pieces of ferrous tramp metal out of the product stream.
GIRON offers both versions to suit your applications and problems. In both cases, the product flows over a totally smooth surface made possible by the succession of wires. The space between each profile creates a gap, known as an interstice, fissure or slot.
In the welded versionThe wire is manufactured by rolling from round wire. Rolling is the most common process, generating a profile with slightly rounded edges. These profiles are then welded to perpendicularly positioned cross-members.
In the curly versionThe trapezoidal wire was stamped from round wire. GIRON’s contoured fissure grids have been developed for over 50 years. Stamping produces protruding edges for high drainage efficiency. These profiles are then assembled on rounds. At GIRON, the steel round is 7 mm in diameter and the loops have a pitch of 70 mm.
This technique guarantees opening accuracy unsurpassed gap widths, especially for very fine cracks. Grids can be supplied flat or curved, bare or with all types of reinforcement such as flats, angles or other accessories.
Thanks to their rectangular mesh, these meshes can make an effective contribution to improving flow, reducing studding or light clogging, or even serving as a de-puffer.
