The RCYD(C) series permanent magnet self-unloading iron separator is composed of high-performance permanent magnet cores, iron rejection belts, reduction motors, frames, drums, and other components, and is compatible with various conveyors. It is used for automatically removing ferromagnetic materials weighing from 0.1 to 25 kilograms from non-magnetic materials. The internal magnetic circuit is designed using computer simulation and features a complete double-pole structure, ensuring the machine operates reliably and without failure in harsh environments. It is also explosion-proof.
