Grate magnets provide a simple, effective solution for capturing ferrous metal contamination in many different magnetic separation applications, including coffee grinders. Grate magnets use a high intensity, expertly configured magnetic field to hold and trap ferrous contamination. The powerful magnetic force traps and holds small metal objects, metal fragments, and even very fine ferrous particles. Installing grate magnets is easy, and in some applications, they can simply be laid inside bins, chutes, hoppers, pits, and other housings to enable easy cleaning. Stainless steel tubing and frames are welded into strong, integral units. The 12,000 Gauss neodymium grate magnet option has a pull strength of 13.2lbs (with a ½” ferrous ball) and can be purchased in square and round options. BuyMagnets.com stocks multiple widths and lengths of grate magnets and provides fast shipping for your convenience.
