HP = Nameplate Horsepower of the motor on the screw conveyor S = Screw Conveyor Speed. The torque rating of the drive shaft, coupling shafts, coupling bolts and conveyor screw must be greater than Full Motor Torque for proper design. A 12inch diameter screw conveyor was selected for the example.
Vertical screw conveyors are a very efficient method for elevating a variety of bulk materials at very steep inclines or completely vertical. KWS considers any screw conveyor located on an incline over 45degrees to be a vertical screw conveyor. The compact design allows for the vertical screw conveyor to fit into almost any plant layout.
Screw Conveyor Torque Engineering Guide. ensp;0183;ensp;Torque is measured in inchlbs. for screw conveyor components. The torque rating of the drive shaft, coupling shafts, coupling bolts and conveyor screw must be able to withstand Full Motor Torque without failing. Every KWS screw conveyor is designed to this
