The formula used to calculate the Screw Conveyor Flow Rate is as follows: Q = 60 * π/4 * D^2 * S * N * a * d * C. Where: Q = Flow Rate (m^3/h) D = Diameter of the screw conveyor (m) S = Pitch of the screw conveyor (m) N = RPM (Revolutions per minute) a = Loading ratio (Percentage of screw cross-sectional area filled with material) d = Density ...

Equation 6 – Bucket Elevator Power Formula – Friction Factor Method. Another way to account for the system friction is to add a multiplication factor to the calculated HP in Equation 3. This multiplication factor typically ranges from 10% to 30%, depending on the application. Consult your Bucket Elevator Supplier for additional information.

An experiment was conducted to investigate the effect of screw speed, inclination angle and variety on the required power, and conveying capacity of a screw conveyor. The experiment was designed with four levels of screw speed (600, 800, 1000, and 1200 rpm), five levels of inclination angle (0, 20, 40, 60, and 80 ∘ ), and three levels …

Belt Pull = Total Weight x frictional coefficient. Belt Pull = 280 lbs x 0.5. Belt Pull = 140 lbs. Then, convert this to required power. Required Power = Belt Pull x Belt Speed. Required Power = 140 lbs x 50 fpm = 7,000 ft-lbs/min. Convert that to a useful unit of measure. One horsepower (HP) equals 33,000 ft-lbs/min.
