Test Results: How Bend Types Influence Pneumatic Conveying System Performance

A conveying line bend is just one of several components you must select for a pneumatic conveying system, but the bend type you choose will have a strong effect on the system's performance. The bend should generate a low pressure drop to miminize the system's energy consumption, and the bend should also minimize particle degradation and wear on the bend walls. In this article the results of a test program at the University of Greenwich and an equation for predicting pressure drop due to bends can help in selecting a bend for your conveying system.
