A Magnetic Drum Separator is a device that uses a rotating drum with a magnet inside to separate magnetic materials from non-magnetic materials. The drum is usually installed above a conveyor belt or a vibratory feeder, and the magnetic materials are attracted by the drum and separated from the material flow. The magnetic materials are then discharged at the end of the drum, while the non-magnetic materials continue to move along the conveyor belt or the vibratory feeder.
Magnetic Drum Separators are used for various applications, such as recycling, mining, plastic, steel, chemical, and pharmaceutical industries, to improve the quality and purity of the products, reduce the waste and energy consumption, and protect the downstream machinery from damage. Magnetic Drum Separators can remove both large and small pieces of iron contaminants, as well as some paramagnetic particles. Magnetic Drum Separators can be manual or automatic, and can vary in the strength of the magnet, the speed and length of the drum, and the depth of the magnetic field.
In Magnetic Drum Separator, material is fed into a rotating shell revolving around a stationary magnet. Ferrous metal remains on the shell surface until it passes through the magnetic field - separating it from the normal trajectory of the nonferrous material. Any ferrous tramp metal is captured by the magnetic field and held on the drum's surface. As the drum rotates, the metal is carried past the diverter and released outside the magnetic field.
