SEPARATOR OF LUMPY MATERIALS Russian patent published in 1994 - IPC

FIELD: mineral concentration. SUBSTANCE: separator includes inclined working member, generator of mechanical vibrations, feeder, receivers of products of separation, shock absorbers, regulator of working member inclination, magnetron, actuating mechanisms and scanning unit for material grade identification whose outputs are connected with inlets of actuating mechanisms installed in row over width at places of lump coming off working member. Working member is hollow widening in horizontal direction and narrowing in vertical plane from feeder to receivers of separation products and connected to magnetron. Generator of mechanical vibrations is mounted on working member through shock absorbers and inclination regulator. When lumpy material gets inside working member, lumps are distributed over width and undergo vibration together with working member. Magnetron sets up SHF electromagnetic field in working member. Field energy is absorbed by lumps that results in selective heating and drying. Scanning unit identifies lump grade and produces signal. Under the action of pusher, lump gets into respective receiver. EFFECT: higher efficiency. 3 dwg
