Design and Analysis of Screw Conveyor

Abstract

Screw 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 (grains), pharmaceuticals, chemicals, pigments, plastics, cement, sand, salt and food processing. They are also used for metering (measuring the ow rate) from storage bins and adding small con- trolled amounts of trace materials such as pigments to granular materials or powders. Current work deals with the design and analysis of screw conveyor for conveying cement at 80tonnes/hr output.Modeling of the conveyor has been done using Solid Edge 19 based upon the dimensions obtained from procedural design as per related IS codes.Furthermore a GUI has been prepared, using Microsoft Visual Basic 2008, which gives the values of diameter and power requirement of screw. Finite Element Analysis of the screw conveyor has been carried out using Ansys 11.0.
