Power draw is an important index in screw conveyor design procedure, and it is related to torque which determines from DEM predictions of the forces exerted by the particles on the rotating screw. Figure 11 shows the relationship between the power draw and the conveying time under the screw rotational speed 150 rpm.
Screw conveyors move materials either horizon tally, on an incline or vertically. They are used to feed, distribute, collect or mix and can be equipped to either heat or cool while performing this transfer. With the proper cover and gasketing, they are easily made dust or weather tight and rodent proof. Their

A summary of current design methods and problems experienced for screw conveyors can be found in Bortolamasi and Fottner (2001). The description of the theoretical behaviour of screw conveyors can be found in articles by Yu and Arnold (1997), and Roberts (1999). DEM modelling of particulate flow in a screw conveyor
2. ENCLOSED SCREW CONVEYORS. The relevant details of the enclosed screw or auger conveyor are shown in Figure 1. The power driven screw flight is supported in bearings and revolves in a stationary tubular casing. Practical limitations require a liberal clearance between the flight and the casing and this has been shown
The rotational speed of the screw body of the vertical screw conveyor is higher than that of the ordinary screw conveyor. under the action of centrifugal force, there is a friction between the conveying material and the casing, which prevents the material from rotating with the screw blade and overcomes the falling gravity of the materials.
Vertical Screw Conveyors. Flexible Screw Conveyors – Conveyor Engineering & Mfg. Co. Vertical screw conveyors are often components in conveyor systems, attached to vats, bins, ovens, hoppers, silos and horizontal screw conveyors. They are most needed when material must be carried from a receptacle low to the ground to one that is very tall.
