Dutch recycler installs sink-and-float plant

Archiv – Well-known Dutch metal recycler Gebr. Gerrits Beheer of Helmond has bought a heavy media plant from ProTec Srl of Genoa, Italy. Expected to come on stream in the autumn, the new sink-and-float plant will replace an existing separation system which has been in operation for almost 15 years.
The new plant includes a pre-washer followed by two 1.5-metre wide eddy current systems (ECS) from Steinert for the separation of non-metallics.Well-known Dutch metal recycler Gebr. Gerrits Beheer of Helmond has bought a heavy media plant from ProTec Srl of Genoa, Italy. Expected to come on stream in the autumn, the new sink-and-float plant will replace an existing separation system which has been in operation for almost 15 years.
The new plant includes a pre-washer followed by two 1.5-metre wide eddy current systems (ECS) from Steinert for the separation of non-metallics. This fraction, the so-called ’rejects’, pass through a single density drum to separate still existing metals – mainly stainless and electrical wire. Metallic materials emerging from the two systems pass through a double density drum which, in a single process, enables the separation of lighter magnesium – often found in European cars – from heavier aluminium, and again from the ‘€˜heavies’€™ such as copper, brass, zinc and lead. This means less machinery, reduced plant size and fewer personnel, according to the manufacturer.
A further 1-metre wide ECS from Steinert is used to separate magnesium from rubber and plastic. The plant also includes conveyors, drain and rinse screens, and a magnetite and a ferro-silicon recovery system. Almost fully automatic, it also features automatic density control of the medias.
Maximum input is calculated at 40 tonnes per hour of shredded scrap measuring 10-100 mm and with a metal content of 50%.
