Multistage Centrifugal Blowers Applications


1) Pneumatic Conveying Applications

DICHENG multistage centrifugal blower has designed pressure and vacuum pneumatic conveying systems to meet a variety of applications. Our DICHENG High Speed Blower with pressures to 98Kpa and low flows is particularly suited for this application.

Pneumatic conveying can be used to move any dry bulk material, including powders, granular forms, chips and pellets.

Types of pneumatic conveying include: Dilute Phase, Dense-Phase, Piston Flow, Piston Permeable, and Piston Non-permeable.
