Mechanical capacity calculated on the drive drum P A Factor C 2 Checking the Transilon type selected In the case of perforated belts please note: calculate the load-bearing belt width b 0 based on the number of per-forations which decrease cross sec-tions. Staggered perforations in partic-ular can reduce the load-bearing belt width considerably.

The capacity calculation for screw conveyors takes into account the outside diameter of the screw, the outside diameter of the center pipe, the pitch of the screw, …

Interactive Calculator » Kase Screw Conveyors can be operated with the flow of material inclined upward. Use this guide to learn more about this conveying feature.

The Screw Conveyor Flow Rate (Q) is calculated using the following formula: Q = (60 * π / 4) * D^2 * S * N * a * d * C. Q: Screw Conveyor Flow Rate (kg/hr) D: Diameter of the screw conveyor (meters) S: Pitch of the screw conveyor (meters) N: Rotational speed of the screw conveyor (RPM) a: Loading ratio; d: Density of the …

Mar 28, 2013. #1. In inclined screw conveyor, as we increase the angle of conveyor from ground, its capacity decreases. Here inclination factor comes in play. Say, if angle of inclination is 15%, inclination factor is 0.75. It means, conveyor capacity will be 0.75times of horizontal conveyor capacity. Now, my question is how this inclination ...
