Magnetic Humps and Round Pipe Separators

Powerful magnetic separator removes tramp iron from free flowing gravity or pneumatically conveyed materials


Magnetic Humps



Eriez Magnetic Humps and Round Pipe Separators

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.

The ferrous contamination remains on the face of the magnets until an operator swings the magnet out of the product flow and physically removes the metal.

Features & Benefits:

  • Quick release clamps for easy operation and maintenance
  • Minimized overall height for difficult retrofit installations
  • All welded construction
  • Mild or stainless steel construction
  • Available for gravity, horizontal or vertical pneumatic installations

Pneumatic Humps

The elimination of tramp iron from materials traveling in pneumatic lines is handled effectively by the magnetic Hump. The assembly consists of two powerful magnets in an enclosed rectangular sheet metal housing. Magnets are hinged to the housing and swing open for cleaning. Standard pneumatic Humps are constructed for installation on the suction side of a blower.

Gravity Flow Humps

The gravity flow magnetic Hump is used for tramp iron removal where heavy, loose flowing materials are conveyed in vertical gravity flow chutes.

Installed vertically the unit is highly efficient, since falling material strikes directly against the first magnet, and the subsequent change of direction permits the second magnet to remove any tramp iron not caught by the first.

Round Pipe Separators

The Round Pipe Separator makes the installation of plate magnets in round gravity flow chutes extremely simple and economical. By building the magnet into a housing designed for efficient and effective tramp iron removal, it eliminates installation expense and assures satisfactory results.

The assembly is installed by merely cutting out a section of the chute where magnetic protection is required, and slipping the separator into position. A Neoprene baffle directs the flow directly over the magnet face, which assists in tramp iron removal.
