Suspension magnets from STEINERT have been extracting iron and iron-bearing components from bulk materials for many decades. They recover clean iron scrap for recycling, and protect grinders, mills and other processing equipment against wear and damage.
STEINERT Suspension Magnets can be used to remove unwanted tramp iron such as screws, nuts and rock bolt from coal, coke, ore and other minerals, even at extremely fast belt speeds (≤ 7.5 m/s), great working distances up to 1 m and high dumping heights.
Municipal waste, coal, ores, demolition scrap, shredder material, scrap wood, glass, foundry sand.
STEINERT Suspension Magnets are distinguished by extremely powerful and far-reaching magnetic fields. They are suspended above a conveyor belt and attract the magnetic parts, pulling them up and out of the material flow. For optimal performance, they should be mounted longitudinally above the outlet of the material discharge unit.
Suspension magnets are often self-cleaning and equipped with a circular conveyor belt; the extracted iron is conveyed out of the magnetic field by carrier bars and then discharged. Pure suspension magnets (manual cleaners) are usually electromagnetic and used for parts with lower iron content and for belts widths greater than 2 m. They only attract the iron. From time to time, a craneway moves the magnet sideways away from the belt conveyor and the magnet is switched off. The iron falls into the designated containers. Coal loaders up to 7000 t/h are typical for these types of magnetic separators. The exceptionally efficient boomerang magnet adapts its magnetic field to the discharge parabola.
Mobile treatment plants are a typical application for permanent suspension magnets. Multipolar magnet systems and neodymium iron boron magnets increase the separating performance and efficiency. At the same time, the weight of permanent suspension magnets can be substantially reduced.
