Analysis of Low Velocity Dense Phase Pneumatic Conveying System to Extend System Conveying Capability

This paper reports the current development of technologies to analyse the conveying performance of bypass low velocity dense phase pneumatic conveying system for transporting powder bulk materials and slug flow low velocity dense phase pneumatic conveying system for transporting granular sized bulk materials. It reveals that the bypass system can be operated at a lowered air velocity than conventional pipe line and slug flow system can be also controlled to operate at a lower velocity zone. Hence these technologies have the potential to extend the conveying capability of a pneumatic conveying system to a broader range of materials, also provide better performance in reduction in pipe wear and product degradation.
