SEPARATOR TO SEPARATE LOOSE MATERIALS Russian patent published in 1994 - IPC

FIELD: minerals benefication and coal dressing. SUBSTANCE: separation of material is exercised on two inclined decks 5, mounted as cascade with slit 6 between them. Material is repeatedly fed on decks by drum 1. Drum rotates on rollers 2. Decks 5 are mounted inside drum 1. Air collector 7 is situated under slit 6. During initial material movement on upper deck 5 coal particles are accelerated faster and jump over slit 6. Rock particles drop in slit. Due to fan-shaped motion of particles on decks material separation along length of drum takes place. In the end of drum coal and rock are moving in different directions. EFFECT: separator is used in process of minerals benefication and coal dressing. 2 dwg
