A screw conveyor with the housing diameter of 15.5 cm, screw diameter of 13 cm and screw shaft diameter 3.5 cm having the length of 150 cm was constructed for conducting the experiments.
Above 45-degrees an inclined screw conveyor is considered a vertical screw conveyor and must be designed in accordance with the KWS Engineering Guide for Vertical Screw Conveyors. As the degree of incline increases, conveying efficiency is reduced and horsepower requirements increase due to the effects of gravity and bulk material fall back.
Vertical screw conveyors are an efficient method for elevating a variety of bulk materials from steep inclines to completely vertical. The compact design allows the vertical screw conveyor to fit almost any plant layout. With minimum moving parts, the vertical screw conveyor is a cost-effective and dependable component of any bulk material handling process.
