CEMA Screw Conveyor Engineering Standard 351-2007
Screw feeders are designed to operate under flooded conditions with a head load of product on the screw or multiple screws. The unit must be designed to overcome the static condition of the screws and the force exerted by the product head load. The product head load exerts a downward force on the screws and creates frictional resistance.
