Dense Phase pneumatic conveying systems - Pressure or vacuum

A vacuum dense phase system is quite similar to a lean phase setup except that a vacuum pump allowing to reach pressure < -900 mbarg should be installed. The inlet of material is usually done through a sender hopper. No specific construction for the sender hopper is needed, which can be an advantage compared to pressure dense phase since the ...

Choosing a Pneumatic Conveying System: Pressure or Vacuum

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.

Vacuum Conveying of Materials

Semi-dense phase vacuum conveying It is recommendable in terms of energy saving and further to treat sensitive products gently, and to protect pipelines from abrasive wear. Densephase conveying needs in certain cases more complex control algorithms than a simple dilute phase conveying since pipeline pressure drop has to be kept in a certain range to keep the solids to air ratio stable.

The Fundamentals of Vacuum Theory - Vacaero

In order to select a vacuum pump, it is necessary to calculate the total conductance of the system being designed. This is usually done as an approximation, with a safety factor added. The pump can then be selected to provide the desired flow rate in each pressure range and the cumulative flow determined over time.
