Operational Problems and Some Solutions

Potential users are often reluctant to install a pneumatic conveying system because they anticipate operating problems. Pneumatic conveyors can have problems but the situation has been improved by the introduction of new types of conveyor or by modification of existing systems, based on a better understanding of the mechanisms of conveying. This often results in a choice of solutions to a particular problem. The most common problems affecting pneumatic conveyors are examined, including particle degradation and particle melting, system erosion, static electricity, explosion risks, and material deposition in pipelines. Some practical solutions to these problems are presented.
