SCREEN Russian patent published in 2003 - IPC

Abstract RU 2203148 C1

FIELD: production and processing of heavy minerals of hard-to-wash out alluvial deposits, namely high-clay deposits or deposits with increased content of fine gold particles. SUBSTANCE: sorting screen includes sieve in undersize space of which rotors are mounted and undersize space. Oversize and undersize spaces are in the form of sections having sieves with different mesh sizes in different sections. Rotors are mounted in each section of oversize space and they are inclined in vertical plane along its horizontal axis. Each section of oversize space is provided with ultrasonic transducer; its bottom is inclined to side of outlet of oversize product. EFFECT: enhanced efficiency and effectiveness of disintegration and screening at processing high-clay alluvial deposits. 4 dwg
