FIELD: mining industry, building engineering. SUBSTANCE: vibrating screen-crusher has load-carrying organ with longitudinal grate bars and inertial booster whose debalances are located between grate bars and protrude above them. Load-carrying organ is mounted on shock absorbers and is equipped with transversal grate bars which are made cantilevered. Transversal cantilevered grate bars connected with neighboring longitudinal grate bars alternate mutually. Material is subjected to screening and is crushed by debalances. Penetration of outside material into below grate product and filling in the spaces between grate bars is prevented. Innovation concerns screening and crushing of mineral resources. EFFECT: enhanced efficiency, enhanced quality of screening. 3 cl, 2 dwg |
