⚙️ CEMA Standards (Trough Loading 15%-45%, Flight Pitch & Diameter Inches, Drive HP)

Industrial Screw Conveyor Calculator

Size horizontal and inclined screw auger conveyors under CEMA Standard 300: calculate volumetric capacity (cu ft/hr and TPH based on trough percentage loading [15% for abrasive materials up to 45% for free-flowing powders]), determine screw diameter (6" to 24"), flight pitch, rotational speed (RPM), motor horsepower (HP), and fabrication margins.
