Design of Pneumatic Conveying System
www.ijirst.orgsolids loading ratio of 10, for example, it could be conveyed in dilute phase or dense phase. It would only be with the value of the conveying line inlet air velocity that the mode of flow could be determined. But in the case of dilute phase conveying the preferred ratio of solid to air is 2:1. Conveying capacity
