Challenges in pneumatic conveying

Challenges in pneumatic conveying have been explored in an attempt to provide the researcher and practicing engineer with a realistic view of the topic. While much has been achieved in the field in both modeling and experimental understanding, one can not rely totally on these predictions for complete design reliability. The most difficult topic is the individual properties of the various materials that are attempted to be conveyed. These material properties place limitations on the designer sometime because of their finest and others because of delicate nature in requiring that no change in the product occurs during the conveying operation. Unusual applications of pneumatic conveying are reviewed including such conditions as electrostatic generation, temperature and pressure effects. © 2000 Hosokawa Powder Technology Foundation.
