SCREW CONVEYOR
The capacity of a Screw Conveyor should be defined in terms of cubic feet per hour. It is also important to determine the maximum capacity the conveyor will be required to handle. This capacity is very often stated in terms of tons or pounds per hour. However, the material to be handled often varies in

Screw Conveyor Flow Rate Calculator
The following equation is used to calculate the Screw Conveyor Flow Rate. Q = 60 * pi/4 * D^2 * S * N * a * d * C. Where Q is the mass flow rate (kg/hr) D is the diameter of the screw (m) S is the screw pitch (m) N is the RPM. a is the loading ratio. d is the loose material density (kg/m^3) C is the inclination factor.

Screw Conveyor Power Calculation | Screw Conveyor Capacity
It must be noted that those formula aim at giving an idea of the size of the screw conveyor (which means its diameter) and the speed at which it will operate, based on some assumptions and some design decisions (choice of screw pitch, inclination). The formula can also be used to roughly check the capacity of an existing screw conveyor power …

The screw conveyors capacity was determined through measuring the weight of conveyed grains over a known time. A weigh scale with an accuracy of 0.01 g (FLINTEC model PTS10000, Sweden) was used for this purpose. The actual volumetric capacity was expressed in bushels (one bushel = 1.244 cubic feet) per hour (ASABE, 2006).
