The working principle of jet milling is based on the physical properties of high-speed jet fluid. Usually, the jet fluid is composed of high-pressure gas or liquid, which is sprayed onto the surface of the material at a very high speed through a nozzle, generating cutting force or impact force to achieve cutting, grinding and polishing of the ...

La technologie des membranes ceramiques pour la production d'oxygene pur connait un interet croissant pour remplacer le procede de distillation cryogenique, tres couteux sur le plan energetique. Cependant, a l'heure actuelle, les flux d'oxygene produits par la technologie membranaire ne sont pas suffisamment eleves pour etre economiquement …

Cet écoulement est reproduit en soufflerie dans une configuration de jet plan descendant entre 2 flux uniformes co-courants. Il est exploré par anémométrie à fils chauds croisés pour différents nombres de Reynolds et rapports de vitesse. L'influence de ces paramètres de contrôle sur le comportement en similitude est discutée.

Résumé: Notre travail est d'étudier qualitativement et quantitativement l'influence de ces paramètres (débit, le temps de remplissage, la pression d'injection, la température d'injection, etc…) sur la forme finale et l'état mécanique des pièces injectées en matière plastique après leur éjection hors du moule. Ce travail est divisé en deux patries très …

Fig. 1 shows the particle size distributions of the powders ground at different classifier frequencies and grinding gas pressures. It is clear that the process parameters of jet mill have a great impact on the particle size distribution of the ground produces. Furthermore, the influence of classifier frequency takes a leading position compared …

The changes in structural and functional properties of the starch after jet milling process are studied. The particle size of starch significantly (p < 0.05) decreases after jet milling and as the classifier frequency increases. Also, the bulk and tap density decreases; while the specific surface area increases and the flowability of the milled ...

Jet milling is a process that uses high-pressure air or gas to pulverize materials into fine particles. The jet mill works by accelerating particles in a swirling motion, using compressed air or gas to produce high-velocity collisions. The resulting particles are then collected in a collector or baghouse.
