The indigenous art of making screw conveyor

A screw conveyor or auger conveyor is a mechanism that uses a rotating helical screw blade, called a “flighting,” usually within a tube, to move liquid or granular materials. They are used in many bulk-handling industries.

Screw conveyors in modern industry are often used horizontally or at a slight incline as an efficient way to move semi-solid materials, including food waste, wood chips, aggregates, cereal grains, animal feed, boiler ash, meat and bone meal, municipal solid waste, and many others.

There are many reasons why a screw conveyor might fail, but the most common cause is improper installation or maintenance. If a screw conveyor is not installed correctly, the moving parts can come into contact with each other, causing friction and, eventually, failure. If the conveyor is not adequately lubricated, the bearings can seize up, causing the conveyor to stop working. In some cases, the screw conveyor might be overloaded, causing the motor to burn out or the drive belt to break.
