Screw Conveyor Flow Rate Formula. The following equation is used to calculate the Screw Conveyor Flow Rate. Q = 60 * pi/4 * D^2 * S * N * a * d * C Q = 60 ∗ pi/4 ∗ D2 ∗ 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.

Portable screw conveyors are used extensively for transferring grain into and out of storage. Diameters typically range from 6 to 12 in., with maximum capacities near 5500 ft3/h. Portable screw conveyors range in length from around 6 to 100 ft. What is the limitation of screw conveyor? Flexible screw conveyors have some limitations which …
drive shaft, coupling shafts, coupling bolts and conveyor screw must be able to withstand full Motor Torque without failing . Every kwS screw conveyor is designed to this criteria with a minimum safety factor of 5 to 1 . The motor on the screw conveyor will stall out before there is a mechanical failure of a screw conveyor component .
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 …
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)) If you would like to increase the speed of the screw conveyor by approximately 15-percent to a new screw conveyor output speed ...

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.
