Title
(EN) A MATERIAL DISPENSING APPARATUS
(FR) APPAREIL DISTRIBUTEUR DE MATIERE
Abstract
(EN)
An apparatus for dispensing fine particulate material comprises a hopper (23) for storing material (T) to be dispensed, a discharge tube (12) having a discharge nozzle (13) and feeding means comprising an auger (25) for transferring stored material (T) from the hopper (23) to the discharge tube (12). The fine particulate material is regulated by a metering means (35) which meters the amount transferred by the auger (25) to the discharge tube (12). Material (T) is transferred to a container (C) to be charged by positioning it against the discharge nozzle so that the auger (25) transfers a predetermined amount of material (T) from the hopper (23) to the discharge tube (12). Material laden displaced air (T') from the container (C) escapes into a settling tube (15) where the material in the displaced air (T') is allowed to settle and fall by gravity into the container (C).

Un appareil distributeur de matière sous forme de fines particules comprend une trémie (23) pour le stockage de la matière (T) à distribuer, un tube d'évacuation (12) pourvu d'une buse d'éjection (13) et des moyens d'alimentation comprenant une vis (25) destinée au transfert de la matière stockée (T) de la trémie (23) au tube d'évacuation (12). La matière en particules fines est régulée par un moyen de dosage (35) qui dose la quantité transférée par la vis (25) dans le tube d'évacuation (12). La matière (T) est transférée dans un récipient (C) que l'on charge en plaçant celui-ci contre la buse d'évacuation de telle sorte que la vis (25) transfère une quantité prédéterminée de matière (T) de la trémie (23) au tube d'évacuation (12). L'air déplacé (T'), chargé de matière, qui provient du récipient (C) s'échappe dans un tube de dépôt (15) dans lequel la matière présente dans l'air déplacé (T') peut se déposer et tomber par gravité dans le récipient (C).
