The Calculation Formula Explained. 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.

Screw conveyors are a cost efective and reliable method of conveying bulk materials. Thousands of bulk materials are conveyed and processed daily utilizing screw conveyors. The KWS Screw Conveyor Engineering Guide is an excellent resource for understanding and designing screw conveyors. The engineering guide is easy to use, with …

the conveyor . For screw conveyor design purposes, conveyed materials are classified in accordance with the code system in Table 1-1, and listed in Table 1-2 . Table 1-2 lists many materials that can be effectively conveyed by a screw conveyor . If a material is not listed in Table 1-2, it must be

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.
