<p>A dosage device particularly for gravimetric mixers, which comprises: a first hollow body (14), which is provided in an upward region with a loading opening (15) that is arranged below the outlet (16) of a corresponding hopper (11) and, in a downward region, with an unloading opening (17) that is arranged above a weighing tank (18), in which there is a second body (19), associated with a corresponding crank system (34, 35, 36) and movable alternately from a position (15) for loading to a position (17) for unloading granules (22) from a pocket (20) formed within its perimetric outline. The first and second bodies (14, 19) provide a coupling by virtue of which only the granules (22) contained within the volume of the pocket (20) are conveyed between the loading and unloading positions. <IMAGE></p> |
