ABSTRACT:
A system for the delivery of bulk material, in particular a free-flowing bulk material such as, e.g., plastic granules, comprises a discharge base (7) having recesses (8), with a discharge opening (9) being formed in each of the recesses (8), and a cover plate (11) which is arranged on the outflow side of the discharge base (7) at a distance (h) from the same, with the cover plate (11) having openings (12) which are arranged essentially in the same pattern as the discharge openings (9) of the discharge base (7). The cover plate (11) and the discharge base (7) are movable relative to each other between an opened condition in which the discharge openings (9) of the discharge base (7) and the openings (12) of the cover plate (11) overlap each other at least partially, preferably being congruent, and a closed condition in which the discharge openings (9) of the discharge base (7) exhibit such an axial offset (s) from the openings (12) of the cover plate (11) that no overlap is produced.
