An apparatus for separating coarse particles from a stream of gas entrained with a mixture of coarse and fine particles includes an outer casing, an inner casing disposed within the outer casing and configured to define a passageway between the outer casing and the inner casing through which the stream of gas and mixture of coarse and fine 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 casing in order to separate the coarse particles from the fine particles entrained within the stream of gas, a plurality of outlets for discharging the stream of gas and fine particles from the apparatus, and at least one 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.
