ABSTRACT
Dust generated from most bulk solids poses a potential health problem, and many materials that have to be conveyed are potentially toxic. Pneumatic conveying is often chosen for hazardous materials because the system provides a totally enclosed environment for their transport. It is also considered that the majority of conveyed materials are potentially explosive, and this certainly applies to most food products, fuels, chemicals and metal powders. Pneumatic conveying systems are basically quite simple and are eminently suitable for the safe transport of powdered and granular materials in factory, site and plant situations.
