ECCENTRIC EDDY CURRENT SEPARATOR (SFME-29 Type)
ECCENTRIC EDDY CURRENT SEPARATOR
FELEMAMG has designed the new SFME-29 eddy current separator, combining the extraordinary efficiency of SFM-29 concentric rotor and the long service life of eccentric shell.
Eddy current separators are ideal for recovery of steel, copper, brass, etc. in breaker’s yards, household large electrical equipment, municipal waste plants, glass recycling plants, plastic plants, treatment of aluminum slag, etc.
The dividing element consists of a magnetic rotor with a diameter of 290 mm, provided with permanent magnets of Neodymium and of high magnetic power. The high frequency magnetic field, induces Foucault currents to conductor metallic parts. These parts create a magnetic field opposed to that of the rotor. The result is a repelling power on the metallic parts, the ferrous elements are attracted by the powerful magnetic field and the rest of the elements follow their ordinary trajectory.
Thus, three different elements are obtained at the outlet of the separator:
Non-ferrous metals, ferrous metals and non metals.
The eccentric shell provides effective protection against iron particles between the rotor and the conveyor belt. The particles will come off automatically on the bottom of the shell.
PRINCIPLE OF OPERATION
This metal separator should be fed from a vibrating feeder to distribute the material over the conveyor belt. When the material reaches the discharging area -location of the magnetic drum- ferrous pieces are pulled by the belt and attracted by the drum until they reach the underside, from which they are discharged. Metallic non ferrous pieces are “thrown” forward, overpass the divider and are collected at the front. Lastly, non metallic pieces follow normal trajectory of the belt from where they are discharged.
