By N. Behera, V.K. Agarwal, M.G. Jones, K.C. Williams – Pneumatic conveying of certain bulk materials is widely used in industries due to certain advantages over other modes of conveying. As compared to dilute phase, dense phase conveying is a preferred method of conveying due to its low power consumption, low erosive wear and low attrition of particles. Fly ash and alumina being high aeration capable due to their fine particle size tend to be conveyed in fluidised dense mode at low velocities. In this paper, details of pneumatic conveying tests are presented which are carried out using fly ash and alumina as conveying material at different solids loading ratios for dense mode as well as dilute mode of flow.
