Abstract
The apparatus includes a feed hopper (39), a vibratory module (20) formed by a sieve (26) and by a first transducer (22) associated with a first resonator (21), said transducer (22) receiving an a.c. control voltage V.sub.com allowing it to transmit mechanical vibrations to said sieve (26, 26') in response, means (30, 40) for locking said vibratory module (20) below said hopper (39), and an electronic control unit (50) arranged to supply said control voltage V.sub.com,. It is characterized in that it further includes a second transducer (24) arranged in proximity to said sieve (26) and in that said control unit (50) includes a stage (55) arranged to receive a measuring voltage V.sub.mes. representative of the mechanical vibrations and to adjust the control voltage V.sub.com of the first transducer (22) in response so as to enslave the powder flow rate value to a predetermined desired value.
