Pneumatic conveying systems: Answers to 3 FAQs
Unlike the dilute phase systems, the dense phase pneumatic conveying system uses low air velocity (usually less than 7 m/s) to transport dense concentrations of bulk solids. These bulk solids are usually not suspended in the conveying air stream, and the low conveying air velocity means there is less wear and tear on the conveying …
