HIGH-ANGLE MAGNETIC CONVEYOR Russian patent published in 2016 - IPC B03C1/18 B65G54/02 

FIELD: metallurgy.

SUBSTANCE: invention relates to metallurgy, mining industry. High-angle conveyor magnetic for separation of magnetic and nonmagnetic components of ground dump steel-smelting slag contains conveying belt and permanent magnets. On whole working surface of transporting conveyor belt permanent magnets are fixed with coercive force of not less than 2900 kA/m. Said tape is enveloped with endless belt made of nonmagnetic material dural D16, D19, alloyed nonmagnetic steel EI 429. Outlet branch of continuous tape made of nonmagnetic material dural D16, D19, alloyed nonmagnetic steel EI 429 rests on squeezing roller equipped with adjusting screw to displace in horizontal plane. Centre of squeeze roller is arranged at distances from two to three diameters of driven pulley from centre of driven pulley. Angle between branch of continuous tape made of nonmagnetic material from dural D16, D19, alloyed steel EI 429 and working surface of driven branch of conveyor belt steeply inclined with permanent magnets is from 30° to 45°. High-angle conveyor is fixed on hinge and is equipped with screw to turn steeply inclined conveyor relative to vertical axis by angle from 0° to 15°. Steeply inclined conveyor drive pulley is equipped with DC motor or alternating current electric motor with controlled frequency current.

EFFECT: technical result is increased efficiency of separation of magnetic and nonmagnetic components of ground dump steel-smelting slag.
