Abstract
L'invention est un dispositif de caractérisation de la granulométrie de poudres comportant un organe d'alimentation, un organe d'évacuation, un organe de pesée, un organe de vibration continue, un organe de tamisage, ainsi qu'éventuellement un organe de pilotage, et caractérisé en ce que l'organe de tamisage est un organe rotatif autour d'un axe horizontal, et dispose d'au moins 3 positions correspondant à 2 tamis de maillage différent et 1 espace de libération des particules les plus grossières (particules n'ayant pas traversées le tamis de maillage le plus grand). Un autre objet de l'invention est l'utilisation d'un tel dispositif pour la caractérisation de la granulométrie de poudres, et notamment leur caractérisation en ligne c'est-à-dire au cours de leur processus de fabrication.The invention is a powder particle size characterization device comprising a feed member, an evacuation member, a weighing member, a continuous vibration member, a sieving member, and optionally a control member. , and characterized in that the sieving member is a rotatable member about a horizontal axis, and has at least 3 positions corresponding to 2 sieves of different mesh size and 1 release space of the coarser particles (particles n having not crossed the largest mesh sieve). Another object of the invention is the use of such a device for the characterization of the particle size of powders, and in particular their characterization in line, that is to say during their manufacturing process.
