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.
Calculation of Torque of Screw Conveyors. Full Motor Torque is the maximum torque exerted by the drive unit. The equation for full Motor Torque is shown below: Nomenclature: HP = Nameplate Horsepower of the motor on the screw conveyor. S = Conveyor Speed. Torque is measured in inch-lbs. for screw conveyor components.
