Eriez' Magnetic Hump and Round Pipe Separators provide a simple and effective way to remove tramp iron contamination from gravity or pneumatically conveyed dry, free flowing products such as feed, grain, wood ships, food stuffs, sand or plastic.
The housing is "dog-legged" on two sides at 45 degrees from a flat plane. Each leg contains a plate magnet hinged and latched to the housing, one on the up stream side and one on the downstream side.
Material enters the magnetic Hump and is forced abruptly to change direction against the face of the powerful plate magnet. As the material tumbles in the housing, it again changes direction and is forced against the face of the second powerful plate magnet. The Hump takes advantage of the ferrous material density because the heavier metallics are more likely to work their way to the face of the magnet, increasing the probability of capture.
