Overband magnet PMT
The PMT type overband magnet is intended for removal of tramp iron from bulk materials transported on belt conveyors or vibrating feeders. The magnetic block protects mills, crushers and other process machines against damage caused by iron parts such as screws, pipe pieces, bearings or crusher teeth. The PMT magnet requires manual cleaning of captured metals.
The PMT suspended magnet is reliable and very robust. The magnet is characterized by high metal separation efficiency. The ferrite or neodymium permanent magnets have high coercivity, which makes them difficult to demagnetize. Therefore, the ovedrband magnet has a long service life.

Working principle of the overband magnet
The magnet is usually suspended on a special support structure above the conveyor belt transporting the material. There are two ways to suspend the magnet - transversely to the direction of the transported material or longitudinally above the conveyor drive drum. The magnet attracts ferrous metals contained in the transported material, which stick to the rubber apron. Cleaning the magnet involves removing the apron from the magnet. Optionally, the magnet can be equipped with a metal scraper that facilitates cleaning.
Why choose our overband magnets?
Permanent overband magnets are available in two variants, with ferrite or neodymium magnets. The magnetic systems produced are made of the highest quality materials using innovative technologies implemented by Magnetix. In addition to the standard catalog offer, it is possible to design and produce a permanent magnet to individual order. To facilitate the process of cleaning the magnet from captured metals, the magnet is standardly equipped with a rubber apron or a scraper made of austenitic steel. The entire production process takes place at our headquarters, without the involvement of external companies, thanks to which we complete orders entrusted to us within very short deadlines.
