ABSTRACT:
A dosing device of a pulverulent material uses an oscillating drive mechanism with straight to-and-fro movement to extract and dose a pulverulent material contained in a hopper with a calibrated outlet aperture, and then to transfer the extracted mass to a removal point. The hopper can be fixed or movable. To measure the mass flowrate extracted from the aperture, the hopper is connected to the mechanism by a flexible blade and bears on a table equipped with a weighing cell formed by a weight sensor. The weight variation indicates the mass flowrate, which can be adjusted by acting on the oscillation frequency of the mechanism, or on the opening of the outlet aperture.
