Screw conveyor. The rate of volume transfer is proportional to the rotation rate of the shaft. In industrial control applications the device is often used as a variable rate feeder by varying the rotation rate of the shaft to deliver a measured rate or quantity of material into a process.
Jul 14, 2014· Based on MY interpretation of what my little slide rule indicates that if you're moving 10,000 lbs of portland cement per hour in an 20 inch diameter screw that is 45% (max recommended) loaded, the screw speed should be about 100 RPM. If the conveyor is 100 feet long the HP required is about HP to move the material.
Jan 09, 2009· From this I calculate the torque to be kN and using an efficiency factor of the power needed would be kW. The driving force is provided by forcing the smooth surface of a grooved transmission belt, driven by the motor, against the surface of the chain block over a distance of

Determine required motor torque for the specific application. 4.
Re: How to calculate the flat form of a flight of screw conveyor. Then the inside developed diamater, B = square root of [ (PI*d)^2+ (P)^2]. Value of PI = 3,... So the developed inside radius of the flight will be: r = Rb => b=Rr; b/r= (rR)/R 1º step R/r=A/B; (Rr)/r= (AB)/B 2º step consider that R is the developed outise radius.
