The first step in sizing a screw conveyor is to determine the diameter. The diameter is a function of the rate of the conveyed material, its density, trough fill level, screw pitch and speed of the screw. To ease the calculation, most screw conveyors are full pitch, meaning the distance from flight to flight is the same as the diameter, and are ...
Belt Length. Avoid coming up short or having a belt that extends beyond use by using calculations based on the conveyor's pulleys. When the head and tail pulley are the same size: L = (D + d)/2 x 3.1416 + 2C. When one pulley is larger than the other: L = (D + d)/2 x 3.1416 + 2C + (D – d)^2 / 4C.
The actual screw conveyor speed is calculated by dividing the Selection Capacity by the capacity at. 1-. 1,873/31.2 = 60-rpm. 60-rpm is the correct speed for a 16-inch diameter screw conveyor with cut and folded flights and short pitch for conveying and mixing 333 cubic feet per hour. Capacity Table.
Power calculation of the screw conveyor. Now we need to calculate the drive power of the screw conveyor. This is important to select the motor, shaft, and bearings. The drive power of the loaded screw conveyor is given by the formula: P H = Power required for the material's progression. P N = Drive power at no load.

Two types of troughs are typically used with inclined screw conveyors: U-trough and tubular housing. The U-trough design is simple, economical, and provides access for maintenance. U-troughs are used in most horizontal screw conveyor applications and inclined applications up to about 20 degrees.
A Screw Conveyor Design Calculator is a powerful online tool that provides support to engineers and technical professionals in designing screw …
The formula used by the Screw Conveyor Sizing Calculator is Q = (π/4) * D² * N * S * Ψ * C, where D represents the screw diameter, N is the rotational speed, S is the pitch efficiency factor, Ψ is the percent trough load, and C is the capacity factor. These variables contribute to the overall operational efficiency and capacity of the screw ...
The Screw Conveyor Sizing Calculator uses the formula: = 4× 2× × ×Ψ× Q=4π×D2×N×S×Ψ×C. Where: Q is the conveyor capacity (in cubic meters per hour, m³/hr), D is the screw diameter (in meters, m), N is the rotational speed of the screw (in revolutions per minute, RPM), S is the pitch efficiency factor, ΨΨ is the percent trough ...

The design of the screw is based on the theory of the inclined plane. The screw conveyor began to evolve in the late 1800s and was used as a means of increasing food and grain production to meet the needs of the rapidly growing American population. The first feed mills used screw conveyors throughout the process.
A 12-inch diameter screw conveyor was selected for the example. The minimum standard shaft size for a 12-inch diameter screw conveyor is 2-inch diameter. The corresponding pipe size is 2-1/2-inch schedule 40 pipe with 5/8-inch diameter coupling bolts. The materials of construction of the screw conveyor is carbon steel.
