Goudsmit recently developed a nonferrous separator designed for use in separating four mm to 14 mm sized fractions from brown goods. The optimum separation result of this new nonferrous separator are achieved through the use of a uniquely configured and very strong magnetic field. By rotating the magnet rotor at a higher speed than with conventional separators, the alternating magnetic field increases, allowing separation of small fractions. The process uses Eddy current technology, resulting in efficient separation of conductors (non-ferrous metal) and non-conductors (product). Applications for these non-ferrous separators for fine fractions are numerous, including the processing of combustion paints, scrap metal, cable waste, glass, household rubbish, wood, plastics, and construction and demolition waste.
This separator technology was recently installed inside the processing facility of Recydur B.V. of Apeldoorn, Netherlands, a company that processes discarded electric and electronic appliances. The installation has an operating width of 1,500 mm. The non-ferrous separator is equipped with a conveyer belt with a variable width of 0.3 to two metres, adjustable from 1.5 to 2.5 m/s, and a fast-rotating Neoflux magnet roll is fitted at the end of the conveyor belt. This very powerful magnet roll creates Foucault currents, which generate an opposite magnetic field causing the non-ferrous metals to jump off the roll. The number of revolutions can be increased from zero to 4,000 rpm, and the separator comes with a control system.
