The magnet filter recently developed by Goudsmit Magnetic Systems B.V. from Waalre can be used in pipelines and serves to deferrise raw materials that are transported under pressure. The filter helps to check incoming raw materials as well as the end product before it is sent to the client. Pneumatic pipelines offer many options for a variety of built-in features. The transports may be ten or twenty metres long. There was a fear that the product would pass the magnets too fast so that the ferrous particles could not be caught, but that fear has proved unfounded. Even the smallest ferrous particles are retrieved from the product flow and attach to the magnets

Most magnetic deferrization systems let go of the iron particles already picked up if they come into contact with a stream of raw materials that is under considerable pressure. But the Neoflux® magnetic filter holds on to these iron particles. Even at extremely fast transport speeds. This makes the system – with a magnetic value of 10,000 Gauss – particularly suited for the deferrization of such products as wheat flour. The magnetic filter can be built in at various points in the pneumatic transport line. At the bottom of the silo there is a rotating sluice valve that guides the product through the vacuum transport without losing any pressure. Subsequently the wheat goes from below to above through the magnetic filter.
