Screw Auger HP/ Torque Calc

[apMechE]

Anyone have a good source for assisting in calculating HP or torque required for screw augers? My application is an auger for the front of a slip form paver. 18'' fight, 6'' tube, 45-60 rpm max, metering concrete in an open trough concept, so pushing material over material. Overall length is approximately 15'.

Are you doing concrete or asphalt?

apMechE,

What is it you don't know?

For a given cutting and lifting force, torque and power are easy to calculate if you have taken engineering. If you need the shear forces and lifting friction of whatever it is you are cutting, you might want to ask in one of the civil engineering forums.
