The proven conveyor for pneumatic transport of dry, granular, and free-flowing bulk materials using the dense phase method.
Pressure vessel conveyors T are used as dense phase conveying systems in the following sectors: foundry and steel industry, glass and ceramics industry, plastics industry, food and feed industry, stone and earth industry, and sanding systems for rail vehicles.
Dense phase conveying is a discontinuous process, operating in alternating “filling-conveying” cycles. A propellant gas (air) pushes the bulk material from the pressure vessel conveyor through the pipeline. During the conveying process, the pipeline cross-section immediately behind the pressure vessel conveyor remains fully filled. Depending on the settings and material properties, plugs form at a certain distance, with these distances increasing along the pipeline. However, no suspension flow occurs.
In each conveying cycle, only the contents of the pressure vessel are discharged into the pipeline. The pipeline remains filled so that each new conveying cycle begins against the full pipeline. This method significantly reduces pipeline wear and material abrasion.
Systems with this pressure vessel conveyor are fully enclosed and operate with minimal abrasion, material destruction, segregation, or chemical reactions. They are space-saving, low-maintenance, and quiet.
