5 Questions (and Answers) about the Pneumatic Conveying of ...

1. What is "pneumatic conveying" and how does it transfer solids? Pneumatic conveying is a technology that enables the transfer of solids in a closed system. It provides for the solids to be mixed into a stream of gas, and uses pressure and/or vacuum to convey the gas stream with the entrained solids.

Dilute phase vs. dense phase pneumatic conveying: What's ...

Jan 13, 2011 · The conveying gas volume and velocity are sufficient to keep the material that's being transported in suspension. The material is being conveyed in a continuous manner, and is not accumulating on the bottom of the conveying line at any point. For dilute phase conveying, a relatively high conveying air velocity must be maintained.

Choosing a Pneumatic Conveying System: Pressure or Vacuum

Aug 30, 2019 · Pressure and vacuum systems can be used for dense (high pressure/low velocity) or dilute (low pressure/high velocity) phase operation. Dense phase conveying systems have a low air-to-material ratio. Velocities are below the saltation level, the critical velocity at which particles fall from suspension in the pipe.
