Abstract

On sépare de la poudre de polynère de son véhicule gazeux dans un séparateur à cyclone d'où elle passe dans une trémie pour en etre déchargée par un alimentateur rotatif dont on règle le régime en fonction du niveau de poudre dans la trémie. On règle le volume du gaz de purge introduit dans le guide de poudre entre le séparateur et la trémie en fonction du régime de l'alimentateur et on règle aussi le volume du gaz de purge au-dessus de l'alimentateur rotatif en fonction des fluctuations de son régime. On parvient ainsi à éviter des colmatages.
