A screw conveyor or auger conveyor is a mechanism that uses a rotating helical screw blade, called a “flight”, within a tube/pipe or Utrough to move Urea materials. Screw conveyors and auger feeder are used in many bulk handling industries; in modern industry, it is often used horizontally or at a slight incline as an efficient way to move Urea materials.
They usually consist of a U-trough or pipe containing a spiral blade coiled around a shaft, driven at one end and held at the other. The rate of volume transfer is proportional to the rotation rate of the shaft. In industrial control applications, the device is often used as a variable rate feeder by varying the rotation rate of the shaft to deliver a measured rate or precise quantity of material into a process. Hence, screw feeders are exclusively used for both the material dosing applications wise loss-in weight dosing and gain-in weight dosing.
