29.10.2018 Conveyor feed boosts eddy current separator yield

Goudsmit Magnetics, Waalre, the Netherlands, has recently developed a conveyor belt feed that is supplied by a product distributor. This prevents clogging of the vibratory chute during the recycling process and increases the yield of non-ferrous metals. Sticky or damp product streams, such as incinerator bottom ash (IBA) and refuse-derived fuel (RDF) adhere to the surface of vibratory chutes, preventing them from distributing the product evenly. The product takes on a preferred orientation (the path of least resistance) preventing formation of a homogeneous layer, which results in reduced yield of non-ferrous metals. Until now, a common solution to this problem was to clean the feed belt or vibratory chute at weekly or monthly intervals. This, however, means unnecessary downtime and extra maintenance. The true cause of the problem is the encrusted vibratory feeder. This newly developed conveyor feed with product distributor prevents this problem by creating a mono-layer that ensures full belt coverage. This results in maximum utilisation of the capacity and separation efficiency of the magnetic separator, as well as longer service life of the conveyor.

A mono-layer is a product layer that has a maximum thickness of a single item; in other words, there are no pieces lying on top of each other. This is important for eddy current separation.
