An apparatus for separating coarse particles from a stream of gas entrained with a mixture of coarse and fine particles includes an outer casing and an inner casing configured to define a passageway therebetween through which th e stream of gas and particles can flow substantially upwardly, a plurality of angled vanes for imparting a rotational flow to the stream of gas and particles as the stream passes from the passageway to within the inner casin g in order to separate the coarse particles from the stream, a plurality of outlets for discharging the stream of gas and fine particles, and at least o ne distribution vane pivotably mounted with respect to the outlets for controlling the distribution of fine particles among the various outlets by affecting the rotational flow of the stream of gas and fine particles.</SDOA B>
