Title (EN) HIGH EFFICIENCY CONICAL MILLS
(FR) BROYEURS CONIQUES À HAUTE EFFICACITÉ
Abstract:
(EN) Screens for conical mills and an improved gearbox and housing for such conical mills are shown and described. The screens are frusto-conically-shaped and include a tapered sidewall with a plurality of openings in the sidewall that may be of uniform size. Each opening is separated from adjacent openings by spacing distances which are shorter at the top of the tapered sidewall and longer at the bottom of the tapered sidewall to thereby reduce the residence time of the powder being milled at the top of the tapered sidewall and to increase the residence time of the powder being milled at the bottom of the tapered sidewall.
(FR) L'invention concerne des cribles pour des broyeurs coniques et une boîte à engrenages et un carter améliorés pour de tels broyeurs coniques. Les cribles sont de forme tronconique et comprennent une paroi latérale conique avec une pluralité d'ouvertures dans la paroi latérale qui peuvent être de taille uniforme. Chaque ouverture est séparée d'ouvertures adjacentes par des distances d'espacement qui sont plus courtes au sommet de la paroi latérale conique et plus longues au bas de la paroi latérale conique pour ainsi réduire le temps de séjour de la poudre étant broyée au sommet de la paroi latérale conique et pour augmenter le temps de séjour de la poudre étant broyée au bas de la paroi latérale conique.
