Neodymium Grate Magnets / Neodymium Hopper Magnets provide a properly configured, high-density magnetic field to trap and hold ferrous fines, fragments, and small metal objects as product flows through them. Stainless steel tubing and frames are welded into strong, integral units. They can be installed – or simply laid – inside hoppers, housings, and bins – and easily removed for cleaning. Grates are built for low-abrasion applications and should measure at least twice the size of your outlet opening, so as not to restrict product flow.

Applications:
Magnetic grids are extremely efficient at removing fine ferrous contamination from free flowing products such as powders, granules, liquids and emulsions.  They are easily placed in hoppers, product intake points, chutes and at finished goods outlet points.
Contaminations such as rust and fine ferrous dust from machinery wear are often too small to be detected by a Metal Detector but are easily removed by these highly efficient magnetic grids.

Grid Types:
1. Round, square, rectangle or any odd shape can be custom made.
2. Bolt on rod grids (not food grade) have a gauss rating of 11-12,000 gauss.
3. Food/dairy grade grids are all 316 stainless steel and fully welded 10-10,500 gauss.
4. Drawer grids (no housing) are placed through the side of a chute covering the chute fully inside with toggle latches holding the unit against the outside of chute.  When ready to clean just undo latches and extract the grid for cleaning.
5. Easy clean drawer type grids have an outer tube with a magnetic rod welded to it’s frame.  When ready to clean, extract the grid then withdraw the magnets and the held contamination just drops off. It is then ready to be placed back into the chute and the product is protected.
6. The standard gap between the magnetic rods is 285mm but they can be closed up if the product can flow through without bridging. Alternatively, the gaps can be opened up utilising deflection bars positioned above the gaps, to help deflect the product closer towards the magnets.
