| Abstract: | Flow characteristics of high density and low velocity pneumatic conveying of medium sise sand and fine lime (solids loading ranging from 47 to 200) are investigated.The acceleration pressure drop, pressure drop and mean solid velocity in the stabilized conveying section were deterndned with measuring pressure variation along horizontal pipeline and mean solid concentration. Moreover, an empirical correlation for solid velocity in high density conveying was proposed. |
