Using screw conveyors to move bulk solid materials
Screw conveyors are generally short to medium in length. Most are a few feet up to 40 feet long, but any length up to 150 feet is common. No curves or bends are possible. If a direction change is needed, then the material usually travels in one direction via one screw conveyor, then drops into another screw conveyor going in the second direction.
Volumetric Flow Rate Calculation for Screw Conveyors
A: The volumetric flow rate of a screw conveyor is affected by the diameter of the screw, the rotational speed of the screw, the pitch of the screw, the density of the material being conveyed, and the cross-sectional area of the screw conveyor.
