SCREW – CONVEYOR
Description:
Screw conveyors are one of the bulk-material transporting devices capable of handling a great variety of materials, which have relatively good flow ability. Flow ability denotes the degree of freedom of individual material particles to move past each other. This characteristic is important in case of screw operation as the screw helix, mounted on a central pipe or shaft, rotates within a fixed trough or tube, pushes the material along the bottom and sides, shearing the material in the radial clearance between the helix and the trough and causing the material to tumble upon itself as the moving face of the helical flight tends to lift the material Screw conveyors may be operated horizontally, or an incline or vertically frequently inclined screw conveyors simplify the conveying system because they can do in one conveyor assembly what otherwise would require a more elaborate combination of horizontal and vertical units.
Advantages
Among the many advantage of the screw-conveyors it is the feasibility of numerous feed and discharge openings. This facility lends itself to the use of screw conveyors to receive and distribute bulk materials for in plant material storage in such a manner that different grades or different kinds of materials may be conveyed to or from the proper storage bins. Screw conveyors like wise may be used for unloading materials from cars, bins or piles, feed mills, cereal processing plants and chemical plants. Screw conveyors are very adaptable to the volume control of materials from the bottom of bins, hoppers, bag dumps, storage piles and the like. In this use they are termed as screw feeders. In the handling of some toxic materials, screw conveyors lend themselves very well because the enclosing trough can be made tight to Contain toxic dusts or vapors, thus reducing personal hazards.
Moreover screw-conveyors can be arranged for cooling or heating of the material in transit. Another use is the blending of several ingredients to make a finished product or to make a pre mix of some product. The conveyor screw can be so fashioned that materials are well blended or mixed in transit.
