High gradient magnetic separators Continuous HGMS Recover particles down to extremely fine sizes
High gradient magnetic separation Continuous HGMS Metso (as Sala Maskinfabrik AB, later Sala International AB) has a long tradition in magnetic separation. Already in the end of the 19th century “SALA” built its first electromagnetic separator. The High Gradient Magnetic Separation, HGMS, dates Continuous HGMS back to early 1970’s when “SALA” acquired MEA, Magnetics Engineering Associates, in Cambridge, Massachusetts USA and founded Sala Magneti
The HGMS is often indiscreetly referred to as WHIMS (wet high intensity magnetic separator). However there are a lot of differences, which places the Metso HGMS in a separate category: • Unlike to the WHIMS, HGMS is capable of handling and recovering particles down to extremely fine sizes due to the possibility to choose a suitable matrix grade with large collection area and to control the slurry velocity during the separation process. • The flushing sequence takes place outside the magnetic zone and this makes the Metso HGMS less sensitive to the content of ferromagnetic material such as...
