A screw feeder is a device that is mostly used to transport varieties of materials at a desired and controlled flow rate. Screw feeders are also called as screw augers. In many studies, there is no distinction between a screw feeder and a screw elevator. The difference between both of them is that a screw feeder is used to transport material in horizontal or inclined arrangement whereas in a screw elevator material is handled in a vertical manner. A screw feeder can transport varieties of particulate matter whether it is a chemical, semi-solid material, plastic, slurry etc. Apart from transportation screw feeders are used to measure flow rate as well as they are used to add small traces of materials (i.e. pigments) to powders. In this paper, design & manufacturing of screw feeder for achieving constant flow rate which is required to supply the material (in this application it is wheat) to the grinding wheels of the flour mill and hence will reduce non-uniform wear of grinding wheels and hence will increase its life.
