A Screw Conveyor Flow Rate Calculator assists in avoiding both overloading and underutilization of the conveyor. Overloading can lead to system breakdowns, while underutilization may result in inefficient processes and wasted resources. Material Compatibility: Different materials have varying flow characteristics.

The capacity is given in cubic feet per hour. Shaftless screw conveyor capacity is calculated using the spiral diameter, spiral pitch, trough loading percentage, degree of incline (if any) and spiral rotational speed. The required speed is then calculated by dividing the required material flow rate by the capacity per revolution.
Now we can easily calculate the screw conveyor output speed (SCOS) using the following formula –. SCOS = (Motor Speed (MS) / Gear Reducer Ratio (GRR)) X (Drive Sheave Diameter (D1) X Driven Sheave Diameter (D2)) SCOS = (1750 / 25) X (3.5 / 7.0) SCOS = 35-rpm.

Screw feeders are volumetric metering devices. A fixed volume of product is discharged with each revolution of the screw. The volumetric capacity of the screw feeder is based on the volume available in the last pitch before the shroud and the speed of the unit. All calculations are based on the capacity given in cubic feet per hour.
