Abstract
An impeller is for separating a conveyed stream of material. The impeller has a central rotatable hub with a plurality of blades extending radially therefrom. The hub and blades form a number of generally wedge-shaped material receiving spaces within the impeller. One set of spaces has a baffle arrangement which is configured to direct material in this set outwardly from the impeller on the upstream side of the baffle arrangement. Another set of spaces has a guide arrangement which is configured to guide the material in this set of spaces outwardly from the impeller on the downstream side of the baffle arrangement. The impeller is particularly useful for separating streams of particulates, such as wood chips, compressed shavings, or the like.
