Dilute Phase Conveying Systems

Whirl-Air is also a specialist in developing dilute phase bulk material handling systems. Dilute phase systems are generally used when conveying non-abrasive materials or where high material velocities and product degradation is not a factor.

In the systems illustrated here, a dilute phase vacuum pressure system unloads a railcar to storage silos with subsequent delivery of products to in-plant process bins. A vacuum blower is used to unload the railcar to a vacuum receiver. From the vacuum receiver a second blower conveys the material to the selected silos by pressure. This system can be set up with manual or automatic selection for silo delivery.

From the silos, a second pressure blower conveys the materials to in-plant hoppers on a keep full or scaling basis with air and material being vented or conveyed back to the respective silos. Dilute-phase systems, like dense-phase are available in both vacuum and pressure conveying systems.
