To calculate load torque, multiply the force (F) by the distance away from the rotational axis, which is the radius of the pulley (r) . If the mass of the load (blue box) is 20 Newtons, and the radius of the pulley is 5 cm away, then the required torque for the application is 20 N x 0.05 m = 1 Nm. Typically, a safety factor is used so that the ...
Screw Conveyor Sizing Flow Rate and Screw Size. Since the purpose of a screw conveyor is to move product from point A to point B, you'll want to determine how fast you want the product to move (this is called the flow rate or capacity). Of course, a screw conveyor can only hold so much material at one time, but the bigger the screw inside …
The drive unit for a screw conveyor is typically designed with a gear reducer and motor. The drive unit for a screw conveyor is not 100-percent efficient. There are frictional losses in the gear reducer and belt/chain reduction. drive efficiency (e) is typically between 85 and 95-percent. sCReW COnVeYOR HORsePOWeR.
Vertical conveying by Screw Conveyor, on the other hand, is quite successful and it remains that a 45° incline or angles approaching this figure, are the most difficult on which to achieve successful conveying. Additional power is needed to convey on an incline. This added power is a function of the power required to lift the material.
