Digidale engg. Co. Is one of the most popular means of conveying. simple, cost effective and reliable. the screw conveyor originated a long time ago and is an invention credited to archimedes. nowadays with the use of modern be used in almost any application. the screw helix can be rolled from a strip of steel to form " helicoids" fighting or discs are pressed allowing customized flight shapes in thick heavy duty steel. all types of exotic metals can be used in order to resist wear or corrosion. the simplicity of the device means many years of virtually maintenance free service. inclined or vertical the screw conveyor is a very inexpensive compact system for the elevation and transportation of bulk raw materials. The key to any successful design is, a through understanding of the characteristics of the material to be handled. this information must be available in order to evaluate the suitability of the screw conveyor to the application, taking into account the action of the screw on the material as well. Typical applications include grain storage, feed mills, cereal processing and chemical plants. used for many mining and process operations they can be equipped with heating and cooling jackets. toxic materials can easily be handled with a screw conveyor because the enclosed trough or tube casing can be made tight enough to contain toxic dust or vapors and reduce hazards to the working and general environment. the material you intend to convey may even be damp or sticky, designs are available for most situations. The screw conveyor has a constant volumetric capacity according to speed. it may be exposed to a head of material and by having a correctly designed flight and with variation in the speed can be used to control and feed equipment at a uniform metered rate down the process stream, eliminating surges in the process. in many situations it is the only device that can be used as a feeder.
