Important Note:
This calculator provides preliminary estimates only. Final conveyor selection depends on material characteristics, moisture, inlet/outlet design, inclination, operating conditions and project requirements. Pitch and inner pipe diameter are considered according to standard screw geometry, but reduced inlet pitch applications may change actual capacity.
