Plug-flow pneumatic transporter for the conveying of granular material such as silica sand ‘S-Type’ conveying of dust resembling materials such as bentonite, coal dust and additives ‘PLI-process’ for the low-wear transport of abrasive materials...

The KLEIN pressure vessel conveyor SP-HL was conceived for the continuous conveying of dry, granular and pourable bulk materials such as silica sand and similar products. The pressure vessel conveyor SP-HL continually feeds the material in portions from the unpressurized inlet vessel into the pressurized conveying line. A smooth and continuous conveying process is ensured by extremely short filling cycles and constant air injection into the conveying line. The advantages of the SP-HL in contrast to conventional conveyors, in which the conveying process is interrupted in order to decrease the...

1. Filling stage The inlet valve is open and the material enters the pressure vessel. The filling process is time-controlled.The flap of the discharge valve is pressed against the sealing edge of the discharge opening by the closing spring and the air pressure prevailing in the conveying line. 2. Closing stage A bellow cylinder forces the inlet cone towards the cone seal, the valve area being simultaneously flushed with air from the nozzle ring. This ensures air-tight closing of the inlet with a minimum of wear. 3. Conveying stage After the inlet valve has closed, air continues to flow from the...

In this example, the conveying velocity for both conveyor types is the same and remains below the level where vibrations in the conveying line and more wear occur. The SP-HL does usually not require any additional air supplies over the length...
