Pressure Drop Prediction in Dense Phase Pneumatic Conveying System for Foundry Sand

Pneumatic conveying of solid materials is used in many process industries where solid particles are carried forward in pipes by the gas and air. For foundry sand air is consider as working media with sufficient high pressure and low velocity for dense phase pneumatic conveying system. Aim of paper is for lowest erosion rate in bend and pipe with sufficient pressure to lift up the particles. Material flow rate through a pipeline is primarily dependent upon the pressure drop available across the pipeline. A basic requirement of any feeding device, therefore, is that the pressure loss across the device should be as low as possible in low pressure systems, and as small a proportion of the total as possible in high pressure systems. Accurate prediction of pressure drop across the conveying system is essential in determining the optimum operating parameters for a smooth conveying operation.
