BACK MIXING DEVICE FOR PNEUMATIC CONVEYING SYSTEMS

摘要

The present application provides a back mixing device for use with a pneumatically conveyed flow of solids having a varying flow rate. The back mixing device may include a nozzle, a chamber in communication with the nozzle, and an exit. The chamber may include an expanded area leading to a restriction such that the chamber creates a recirculation pattern in the flow of solids so as to smooth the varying flow rate though the back mixing device.
