The chute magnet system has been developed for thhe efficient removal of iron particles from raw materials which do not flow freely, such as powders, and tacky or oily products, and/or scrap. The system is installed in one of the pipes used to transport thhe raw materials during the production process. The unit is located in a fully welded stainless-steel housing which can be installed in the pipe in a manner such that it in effect constitutes an integral part of the pipe.

Chute magnets are characterised by the location of the magnet poles outside rather than inside the product flow. Extremely powerful plate magnets located on opposite sides of thhe housing capture iron particles contaminating the product flow. These magnet plates are actually of a strength such that the external core is suitable for use with a column of material. The standard system is equipped with two intermediate panels which swivel together with the magnets. On swivelling the magnets further open than the intermediate panels the separated iron particles are released ready for collection. To prevent particles captured by the magnets from being released into the product flow each intermediate panel is fitted with two sloping poles.

The overall height depends on the bore of the housing. Since no parts obstruct thhe product flow they are ideally suited to high-throughput systems. Chute magnets can, in consulation with Bakker Magnetics, also be installed at an angle. The BKM/VI chute magnet can also be used in pipes used for pneumatic transport at an underpressure. Please contact jos for information about maximum transport speeds. The BKM-HD/VI chute magnet is available for use in pneumatic-transport systems operated at an overpressure. Systems for horizontal pneumatic-transport pipes are available on request.
