The axle member has a tapered gripping portion for engagement within an aperture carried by the rotatable body. A tightening element is provided and is extendable through the hollow axle member into securing contact with the body to attach the axle member to the body in rotation-transmitting engagement.A material deflecting chute comprises a concave surface and a plurality of walls on the concave surface forming channels which are widened from an intake end of the chute toward a discharge end thereof.
