Apparatus for coating jet milled particulates onto a substrate by use of a rotatable applicator

Abstract

A film coating apparatus and feed system therefor which comprise: (a) a feeder for dispensing a particulate material at a substantially uniform rate; (b) a jet mill which receives the particulate material from the feeder, wherein the jet mill processes the particulate material by breaking up particle agglomerations and by dispersing substantially uniformly the particulate material into a carrier fluid to result in a processed particulate material; (c) a substrate coating assembly comprising a rotatable applicator; and (d) a tubing having a material receiving end to receive the processed particulate material from the jet mill and a material feeding end to dispense the processed particulate material to the substrate coating assembly, wherein the feeding end is adjacent the surface of the applicator.
