<p>The present invention relates to an apparatus for feeding material into a silo (1) and for discharging it therefrom, comprising an upwardly extending screw conveyor (30) having an upper discharge end (16) which is at a higher level than that of distributor means (11, 15, 27) provided for distributing material being introduced into the silo. The conveying screw (19) of the screw conveyor is disposed in a vertical duct or pipe (2) rotatably arranged in the silo. The distributor means comprises a feed plate (11) attached to the upper end of the pipe (2). A spiral-shaped discharge arm (26) attached to the lower end of the pipe (2) conveys material on the bottom (4) of the silo towards the opening (3) at the lower end of the pipe (2). A horizontal screw conveyor (13) at the upper part of the silo conveys the material to the opening (15) above the feed plate. The material being discharged from the silo is taken away by the same horizontal screw conveyor (13).</p> |
