Screw Conveyor Calculator is a professional engineering tool for calculating screw conveyor capacity, conveying speed, and power requirements. It is designed for engineers, process designers, conveyor manufacturers, maintenance professionals, fabrication specialists, and students working with material handling and conveying systems. The app provides fast and convenient calculations for screw conveyor design and operation, helping users estimate material capacity, conveying velocity, and drive power requirements without relying on manual calculations or spreadsheets. Included Calculators • Screw Conveyor Capacity Calculator • Screw Conveyor Speed Calculator • Screw Conveyor Power Calculator Screw Conveyor Capacity Calculate the material carrying capacity of a screw conveyor based on the conveyor geometry, rotational speed, material properties, and loading percentage. Input parameters include: • Screw Diameter • Shaft Diameter • Screw Pitch • Rotational Speed (RPM) • Material Specific Gravity • Loading Percentage The calculator provides full-load and partial-load capacity results, with outputs available in kg/hr or lb/hr and additional reference values in ton/hr and ton/day. Screw Conveyor Speed Calculate screw conveyor conveying velocity based on screw diameter and rotational speed. Results include: • Conveying Velocity • m/s or ft/s • m/min or ft/min This provides a quick reference for evaluating material movement through the conveyor. Screw Conveyor Power Estimate the power required to operate a screw conveyor based on conveyor capacity, conveyor length, load factor, and friction resistance. Power results are provided in: • kW for Metric units • hp for Imperial units Additional converted values are provided for convenient reference.
