Magnetic Drum Separators are used to separate metal particles from slurries, granules, or powders. These continuous self-cleaning drum magnets are ideal for applications where there is a high level of ferrous and paramagnetic contamination.
In its most basic form, magnetic drum memory is simply a metal drum or cylinder, coated with a ferromagnetic recording material. Stationary write heads emit an electrical pulse, changing the magnetic orientation of a particle at a given position on the drum.
