Abstract: 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.
