Pressulre drop and slug velocity in low-velocity pneumatic conveying of bulk solids

摘要

Low-velocity slug flow pneumatic conveying is being applied increasingly in industry and to a wide range of bulk solid materials. However, to date, most investigations have focused on bulk solid materials with regular shape *e.g. plastic pellets, wheat) and very little work has been undertaken with irregular-shaped materials (e.g. muesli, maize germ). In this paper, a new test-design procedure is presented. Based on particle properties and data from a simple vertical test chamber, the pressure drop and slug velocity in low-velocity slug flow can be predicted accurately in large-scale systems.
