• ### Maximum Conveyor Angle of Inclination

· Example: Conveyor 180 ft. horizontal distance, 48 ft. lift. Divide by 2, giving 90 ft. and 24 ft. The intersection of a vertical line from the*90 ft. HORIZONTAL DISTANCE with a horizontal line from the 24 ft. LIFT would occur at a point (on the 15° line) corresponding to a radius length of 93 ft. (approx.). Multiplying by 2, the actual incline length is 186 ft. The angle is 15° in both cases ...

• ### Shafted Screw Conveyors vs Shaftless Screw Conveyors

A shafted screw conveyor can run at higher rpms because there is no concern about liner wear. Cons of a shafted screw conveyor: The need of hanger bearings for longer conveyors. These may obstruct material flow in high capacity conveyors. Shafted screw conveyors have a lower fill rate due to the need for hanger bearings. The usual fill rate for ...
