FIELD: oil refining, coal, by-product coke and mining industries. ^ SUBSTANCE: invention is designed for screening petroleum coke. Proposed vibrating screen has box with sieve installed with tilting on resilient supports and provided with vibrodrive, crushing bar grate installed on resilient supports for displacement along box at angle towards initial material flow, for instance, petroleum coke, belt conveyor and receivers for separated products. Belt conveyor is installed before discharge end of screen and is provided with strip plates hinge-secured over conveyor for uniformly distributing large lumps of petroleum coke rolling over conveyor. Screening surface of screen is tilted towards flow of initial material, and bars in crushing grate are arranged in fan-like manner towards tilting of screening surface of sieve. ^ EFFECT: improved efficiency of screening. ^ 3 dwg |
