A portion of the housing is perforated to provide a tubular screen, and the conveying member includes projecting agitation tabs along a length thereof which is coincident with the perforated portion of the housing, to propel the mixed material in the housing towards the screen so as to urge the unwanted particulate contaminants out of the housing leaving the granular material therein for conveyance to the outlet.
