Neodymium Separation
NdFeB Separator Rods and Separator Grids
Magnetic Separator Rods and Magnetic Separator Grids are used to remove ferromagnetic debris from materials passing through the grids and past the rods. They are placed in the line of flow of material. Uses include removing ferrous contamination from sugar, rice, animal feed, plastic granulates, shredded paper, tea, chemicals, powders, shredded copper, flour, etc.
Ferromagnetic materials include most mild steels, a few stainless steels, iron, nickel, cobalt and manganese. “Non-magnetic” materials such as aluminum, silver, gold, many stainless steels and copper, will not be moved by magnets (ignoring paramagnetic and diamagnetic effects, which are very weak).
The Separator Magnet Rods are food quality stainless steel encased and usually contain NdFeB magnets. Corrosion resistance and ease of cleaning is given by using the stainless steel.
The method of manufacture is similar for the entire stocked 25mm diameter Magnetic Separator Rods. So although all the longer units are 10000 Gauss rated, the smaller units, although made by the same method, will offer more towards 8000 Gauss because there is simply not enough magnet material present to give the 10000 Gauss (it is still referred to in the industry as 10000 Gauss rated due to its method of manufacture being the same as the longer units). The Magnetic Separator Rods is rated to +80 degrees C.
The ends of the stock Separator Magnet Rods have M8 tapped holes allowing ease of assembly
to other rods or to other components (e.g. framework).

The Magnetic Separator Grids exist in Circular and Square designs. Commonly referred to as Hopper Magnets as they fit within either Square or Round Hoppers. Like the Separator Rods, they are made using food quality stainless steel.
The Circular Magnetic Separator Grids exist in sizes ranging from 100mm diameter up to 500mm diameter in 50mm increments as stocked items. The Square Magnetic Separator Grids exist in sizes ranging from 100mm x 100mm up to 500mm x 500mm in 50mm increments as stocked items. We can produce larger, smaller and bespoke design sizes upon request as part of our custom service. Our stock range is given below:-
