High Quality Standards at Granexport Improved with Eriez Magnetic Hump

Granexport wanted to remove any small contaminants (10mm and below) of ferrous metals from a pipeline of continuously flowing granular corn (2-8 mm dia). The product flows from a freefall height of 1000 mm with a moisture content of 14%. Eriez provided a solution by supplying a Magnetic Hump Separator.

Eriez Magnetic Hump Separators are effective at eliminating ferrous contamination from materials falling under gravity or conveyed in pneumatic lines. Material entering the Hump is forced to change direction by an Eriez Plate Magnet. With ferrous metals being attracted to the magnet the remaining material slows and changes direction to pass over a second Plate Magnet. This ‘dog leg’ design takes advantage of the ferrous metal density with the heavier metallic’s working their way to the magnet, increasing the probability of capture.

The Magnetic Hump Separator that Granexport installed utilized two different strength plate magnets. The top Plate being a Ferrite Superpower KJC Plate to attract medium to large sized tramp metal contaminants and the second a Rare Earth KJB Plate to remove fine iron and weakly magnetic particles.

Granexport commented, “We are very happy with the new installation provided by Eriez. Not only is the magnet doing a good job at improving the quality of our product, it is also protecting our other machinery against tramp metal damage.” Eriez are continuing to work with Granexport with the aim of providing more units in the future to improve quality further.
