Neodymium magnet is also know as NdFeB or Neo Magnets these are made from Neodymium, Boron, Iron and other minor elements. Neodymium magnets are considered to be the strongest compared to Alnico, Samarium-Cobalt and Ferrite magnets.
Magnetic grates are fabricated by a row of magnetic rods that fit into a frame of various shapes. Shapes can be a square, rectangle, circular, triangle etc. Magnetic grates are useful in separating ferrous contaminants from free flowing materials. These frames can also be fabricated as casing for easy cleaning purpose. Magnetic grates can be easily installed on hoppers, ducts, chutes etc. Frame and outer core of rods are made of 304 or 316 stainless steel. Maximum magnetic field strength can reach 12000 Gauss.
