FIELD: mining. ^ SUBSTANCE: invention is related to mining industry, namely to devices for concentration of magnetite ores. Separator-analyser comprises nonmagnetic rotary drum with varied number of rotations and magnetic system with varied configuration of magnetic field, arranged near drum. Separator comprises feeder and receivers of separation products. Magnetic system is made of permanent magnets Nd-Fe-B in the form of right-angled parallelepipeds, to which permanent magnets are attached to two opposite sides with magnetic torques directed to one side installed in separate cylinders with the possibility of their rotation by 180 around axis and fixation. ^ EFFECT: improved efficiency of separation. ^ 2 dwg |
