As an example a regular flight conveyor may be able to convey 9 tons/hour whereas a cut flight screw would convey tons/hour Cut and fold This is a slight variation of the cut flight screw Rather than completely removing material from the flight a small section is cut and folded out of the flight creating a small arm

the length i am considering for the conveyor is meters i am considering Regular pitch double type screw conveyor pedal flight type i think that smaller pitch will definetely apply more force not only because of the pitch but the resistance of pushing the material will also increase and hence demanding for a higher bkw for the same amount
