The product stream flows through a row of 1” diameter magnetic tubes, located on 2” centers, allowing 1” of space between each tube. The tubes are held in place with a stainless steel support frame. As tramp metal contaminants are captured, they move to the underside of the magnetic tubes, eliminating tramp metal “wash-off.” MPI Grate Magnets are designed for easy removal and cleaning of collected tramp metal.

Designed for fine, free flowing product streams. This diverter design has a 90° bend to assure the maximum contact of product onto the magnetic tube.


Recommended for medium size product streams. The 60° bend permits a smooth product flow while still forcing the product over the magnetic tubes.


Designed for coarse, granular product streams. These diverters are designed with .375” dia. stainless steel bars, providing minimal product flow deflection.;
