Mobile magnet system separates both ferrous and non-ferrous

Cooperation between Dutch company Goudsmit Magnetics of Waalre, and German company Sortatec, has resulted in a mobile metal separator that separates both ferrous and non-ferrous metals from bulk flows.

The companies will jointly demonstrate the Goudsmit Mobile MetalXpert at Recycling Aktiv in Karlsruhe, Germany (outdoor area, stand F356). 

The magnetic separator is easy to position, and is designed for coarse bulk flows such as shredded wood. This enables ferrous pieces, such as nails, screws, staples and hinges, as well as non-ferrous pieces such as door handles and strips, to be removed from bulk flow waste. The result is three separate material flows: ferrous, non-ferrous and clean (inert) bulk material which can then be reused. In addition to wood, the mobile machine is also suitable for construction and demolition waste, refuse derived fuels, industrial waste and so forth.

A spreading plate provides the infeed and breaks up the bulk, which then distributes the material over an angled feeder belt. This monolayer is ideally suited for use with an over band magnet that removes the iron out of the flow and, if desired, diverts them to the left or right. After the iron parts are removed, the bulk is transported to a 2m wide eddy current separator. There a powerful 22HI rotor separates the non-ferrous metals from the bulk material.

The metal separator has a capacity of 100m3/h and is fed by a 2,000mm wide feeder belt with speed control. The robust ferrite over band magnet contains material guide chutes, with the eddy current separator having a 2,000mm wide 22HI rotor spinning at 3,000rpm, with both discharge belts being hydraulically height adjustable. The mobile unit is built on a single axle trailer and is suitable for public roads.
