Dense Phase Fluidizing^™ Concept

The Fluidizing Concept is the second most economical design offered by Dynamic Air. This concept is generally suitable for shorter conveying line distances and very fine and non-abrasive powdery materials, such as talc or flour. The Fluidizing Concept is a batch type system that consists of a fluidizing transporter and conveying line.

The fluidizing pressure vessel employs fluidizing nozzles or membrane to "fluidize" the material during the conveying cycle, eliminating packing in the transporter vessel and promoting flow. This action is so effective it makes most powdery material flow much like a liquid.

During the filling cycle, material gravity feeds into the transporter through an inflatable seated butterfly valve. Displaced air is vented up through a vent valve to allow easier filling.

Once the transporter is filled, as signaled by a level control or weighing device, the inlet valve and vent valve close and seal. High pressure air is then introduced gradually through the top of the transporter and fluidizing nozzles or membrane. Then, all air required for conveying is introduced into the transporter during the complete conveying cycle.

The compressed air introduced in the transporter mixes with the material. The material is then forced through the conveying line in a fluidizing condition and continues to convey until the transporter and conveying line are empty.

When the conveying line becomes nearly empty, the pressure in the transporter falls to zero and the air supply turns off, allowing the residual air volume to purge the transporter and conveying line.

Characteristics of this system are high air flow throughout the transport cycle and lower conveying pressures.
