LOOSE MATERIAL SEPARATOR Russian patent published in 1994 - IPC

FIELD: mechanical engineering. SUBSTANCE: separator has several spiral chutes 1 which, in turn, have load trays 3 located stagewise. Load device 4 is made in the form of a divider-proportioner with windows located at different levels with intervals similar to intervals of spiral chutes 1. Load trays 3 are made with slope at the bottom smoothly decreasing from above to the bottom in the longitudinal direction and increasing in cross direction. Dividers 10 of separation product receivers are mounted behind the lower edges of spiral chutes 1 on axles 15 for rotation and have members in the lower part in the form of a two-sided pyramidal surface expanding down and towards spiral chutes 1. The separated mixture enters spiral chutes 1 in adequate flows through controllable windows of divider-proportioner 4 and load trays 3. EFFECT: improved structure. 8 cl, 6 dwg
