On our stand, we will be presenting our brand new Eddy Current Separator, which features an Eccentric rotor design. Master Magnets responded to customer demand and the ever increasing cost of manufacturing by bringing this new design to market. In a select range of applications, the use of an Eccentric Rotor can prove to be more efficient than a Concentric rotor.

The new addition to the range will therefore provide Master Magnets with a wider selection of units to choose from and enable them to provide the most cost effective units for a customer’s specific application.

Concentric rotors

The Concentric rotors consist of an alternating pole Rare Earth magnet system, which completely fills the space available within the separation rotor drum. The magnet system rotates at high speed within a few millimetres of the outer shell surface generating very high ‘eddy currents’ on the surface resulting in very high repulsive forces.

Eccentric rotors

The Eccentric design differs in that the magnet system is of a smaller diameter and is located in an eccentric position to the outer rotor drum. The magnet system is positioned close to the surface where the conveyed feed material is leaving the rotor due to its natural trajectory. This design gives an efficient separation but leaves a ‘dead’ magnetic area at the bottom of the rotor so that any attracted ferrous falls away extending conveyor belt life.

The Master Magnets technical sales team will be available to discuss the new Eccentric design together with the complete range of Master Magnets equipment that includes Overband Magnets, Drum Magnets, Magnetic Head Pulleys, Suspension Magnets and a range of Industrial Metal Detectors.
