A Review on Numerical and Experimental Study of Screw Conveyor

Screw (Auger) conveyors are widely used for transporting and/or elevating particulates at controlled and steady rates. They are used in many bulk material applications in industries ranging from industrial minerals, agriculture, chemicals, pigments, plastics, cement, sand, salt and food processing. They are also used for metering (measuring the flow rate) from storage bins and adding small controlled amounts of trace materials such as pigments to granular materials or powders. Many studies on screw conveyors were conducted to examine performance and to develop new types [1]. Most of these studies were experimental in nature. The purpose of this paper is to present a critical review of current explanations on the working concept of a screw conveyor. Although many experimental and numerical studies on the screw conveyor have been made. In this paper, design and analysis of screw conveyor for different material is discussed. Some researcher used a DEM method to predict the performance of screw conveyor is also discussed. This discussion will be helpful for future research.
