White et al. (1962) indicated that screw conveyor capacity increased with screw speed until some limiting capacity was reached. Lack of increased screw capacity at high speeds probably resulted from increased centrifugal force acting on the stone at the outer edges of the screw. Such action forces stone away from the screw intake and impedes flow into the screw. Also, conveyor capacity is
