Pickup Velocity for Pneumatic Conveying | Powder/Bulk Solids

Jan 13, 2010· David Mills, PhD Two basic modes of flow are possible for materials in pipelines: dilute phase or suspension flow, and dense phase or nonsuspension flow. For dense-phase conveying there are two possibilities, dependent upon material properties. One is sliding bed flow, for materials that have good air retention, and the other is plug flow, for materials with good permeability.

Pneumatic Conveying Excel Workbook Eloquens

The key difference between pneumatic and hydraulic/slurry conveying of solids is that the carrier gas will expand continuously as it goes along the pipe. The flow regime in the pipe (dense or dilute phase) will depend on the ratio of gas to solids and the characteristics of the particles. This workbook contains 2 sheets: Dilute Phase Properties

The Importance of Particle Velocity in Dilute Phase

In open end pipe line suspension flow, or dilute phase pneumatic conveying, proper particle velocity is critical to continuing productivity and product quality. Until recently, measurement of actual particle velocity within the pipe has not been practical outside the laboratory.

Simulations of Dense-phase Pneumatic Conveying

matic conveying: dilute and dense phase con-veying. Dilute phase conveying has been stud-ied in much detail, but not dense phase convey-ing. Analysis of the latter is difficult, because particle interaction is important. One observes particle density waves that are difficult to treat with simple models. Dense-phase conveying can be further
