Dense Phase Full Line Concept^™ - Batch

The Full Line Concept offered by Dynamic Air is generally suitable for longer conveying line distances and very fine granular, abrasive, non-abrasive, fragile and difficult-to-handle materials such as carbon black, silicon carbide, plastic pellets or silica sand. The Full Line Concept is either a batch type or continuous system that consists of single or multiple transporters and a conveying line with Dyna-Chek 4 booster fittings.

From an operating viewpoint, the main difference between the Full Line Concept and all three other concepts is that the Full Line Concept never allows the conveying line to become empty. The conveying line always remains full at the start and end of a conveying cycle.

The batch type system cycle begins with material feeding 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 and vent valves close and seal. The outlet valve then opens and compressed air is introduced into the transporter to displace the conveyed material.

All other compressed air used for conveying is added through the booster fittings spaced along the conveying line.

When the transporter is completely empty, as signaled by a low level control, the compressed air is turned off and material stops in the conveying line. Prior to refilling of the transporter, the air pressure inside is vented through a special vent valve that remains open during the filling cycle. Because the conveying line does not purge itself, the high velocity normally seen with the other three concepts during the purge cycle is eliminated, making the Full Line Concept ideal for abrasive and/or fragile materials.

Since the line always remains full, no time is lost in emptying and filling the conveying line. In addition, air consumption is drastically reduced, making the Full Line Concept ideal for long conveying line distances and where a single material is being conveyed.

Characteristics of the Full Line Concept system are very low air flows throughout the conveying cycle and high conveying line pressures.
