Screw conveyors, sometimes known as auger conveyors, are pieces of industrial machinery used to move large volumes of granular solids, semi-solids, liquids, and even non-flowing materials. By removing the need for the employees to ᴍᴀɴually move loads, they maintain great operating efficiency. The main component of a screw conveyor is a revolving screw shaft that is mounted inside a trough. The material is linearly moved by the screw shaft as it revolves. They can be made to offer straight, angled, and vertical movement pathways.
There are ᴍᴀɴy screw conveyor designs that are intended to ᴍᴀɴage various material behaviors. Bulk materials could be toxic, hygrosᴄᴏᴘic, fluidizing, non-free-flowing, or abrasive. Products including cereals, fertilizers, animal feeds, ash, gravel, cement, and solid wastes are handled using screw conveyors.
The Archimedes screw, which was created in approximately 250 B.C., was the original screw conveyor. A positive displacement pump called an Archimedes screw was employed to raise water from low-lying areas to the raised irrigation ditches. Archimedes screws have undergone construction and drive system upgrades throughout the years to enhance their effectiveness, robustness, and speed while preserving the fundamental mechanism.
The major part of a screw conveyor is the conveyor screw, which is in charge of forcing the particles through the trough’s whole length. It consists of a shaft with a broad blade wrapping helically around the length of the shaft. Flight is the name for this helical structure. Conveyor screws function like huge screws, moving material one pitch as they complete a full rotation. The axial distance between two flight crests determines the conveyor screw’s pitch. The conveyor screw revolves to transfer the material along its length, but it doesn’t move axially or out of place.
Standard Pitch Screw Conveyors
The pitch and screw diameter are equivalent in standard pitch screw conveyors. The radial separation between two flight crests called the screw diameter. They are frequently utilized in inclined screw conveyors with an inclination of under 10° and horizontal screw conveyors. They can handle the majority of materials.
Variable Pitch Screw Conveyors
The pitches rise unevenly during the screw flight in variable pitch screw conveyors. In order to provide the supplied materials more room as they are discharged from hoppers, bins, or silos, the pitch is longer on the input side. Screw feeders employ variable pitch screw conveyors to deliver materials at a specified volumetric flow rate.
