Screw Conveyor Capacity Calculator
Calculate screw conveyor volumetric and mass throughput based on screw diameter, pitch, RPM, and trough loading %.
💡 Engineering Knowledge PrimerScrew conveyor (auger) capacity depends on screw diameter, pitch, rotation speed (RPM), and trough fill percentage. Standard industrial trough loading ranges from 15% (abrasive/heavy materials) to 45% (free-flowing light powders).
OPERATING LIMITS — Throughput calculation limited to the declared loading assumptions; equipment sizing requires material and manufacturer data.
