The high-intensity magnetic plate is a permanent flat-type magnetic separator using neodymium or ferrite magnets with a 304/316L stainless steel housing. As materials pass over the plate, ferrous contaminants are captured by the strong magnetic field. Suitable for chutes, conveyors, and feeding inlets handling powders, granules, and small bulk materials, it achieves over 98% ferrous removal efficiency with easy installation, maintenance, and zero operating energy consumption.
