Pickup Velocity for Pneumatic Conveying

2010/1/13For dilute-phase conveying, values are typically up to about 15, although they can be higher if the pressure gradient is high, as with a short pipeline or a high pressure drop. For the dense-phase flow of materials, such as fine fly ash and cement, values can be in excess of 100, and again higher values can be achieved with a short pipeline or a high pressure drop.

Pneumatic Conveying Systems

Pressure Conveying - Lean Phase Lean or dilute phase pressure conveying systems one of the most common conveying methods used for powders and granules, such as sugar or flour. The system uses positive displacement blowers - providing air at up to 1 Bar (g) - to convey materials through a pipeline to a destination where the air and product are separated by a filter.
