How to minimize particle degradation in pneumatic conveying systems
Particles transported in a pneumatic conveying system can degrade either as they pass through the feeder or as the particles flow through the system and impact other particles, the pipeline walls, or pipeline fittings. This article discusses some ways to minimize particle degradation in pneumatic conveying systems, including choosing a dilute- or dense-phase system, stepping pipeline diameter, and simplifying pipeline configurations and selecting pipeline bend geometries and materials.
A pneumatic conveying system can safely transport hazardous or dusty materials as well as solve other handling problems. Yet you may have heard that a pneumatic conveying system can cause particles to degrade to an unacceptable degree. If this has prevented you from installing a pneumatic conveying system in your plant, you should know that particle degradation can be minimized in several ways.
