Inclined Screw Conveyor Calculation Mechanical ...

2014-7-14  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 factor affects motor ...
