An impeller (12) for separating a conveyed stream of material has a central rotatable shaft (12) with plural blades (47, 48) extending therefrom. The shaft and blades form a number of generally wedge-shaped material receiving recesses (64, 66) within the impeller. One set of spaces has baffle means (82) which are configured to direct material in this set outwardly from the impeller on the upstream side of the baffle means. Another set of spaces has guide means (76) which are configured to guide the material in this set of spaces outwardly from the impeller on the downstream side of the baffle means. The impeller is particularly useful for separating streams of particulates, such as wood chips, compressed shavings, or the like.
