DEVICE FOR CONCENTRATION OF MATERIALS WITH MAGNETIC PARTICLES Russian patent published in 1998 - IPC

FIELD: concentration of materials with magnetic particles. SUBSTANCE: device has launder with regulated angle of inclination and separated into sections by transverse partitions with movable parts and looseners inherent in each partition; appliances for unloading of concentrated mineral; turning of folding frame with magnets located under launder bottom and transverse loosener in bottom layer of sand in launder, in front and rear of each movable plate. Movable plates, looseners and frames with magnets move in synchronism, reciprocating along the launder with the help of common or individual drives. EFFECT: provision of concentration of finely dispersed particles, minerals of heavy fractions, and increased recovery of valuable components due to preservation of relatively high capacity of device by sands and disintegration of plastic and loose clay inclusions. 2 CL, 3 DWGd
