Pressure conveying. Pressure conveying, which is also referred to as positive conveying, is the process of using compressed air to "push" a bulk material through a pipeline. For example, cement is dropped into a pipeline from a silo. There, at the starting point of the pneumatic conveying process, it is moved through the length of the ...
Vacuum Breaker Valve. Vacuum Breaker Valves permit automatic switching from vacuum (conveying mode) to atmospheric air. This enables the blower to run continuously, preventing it from having to start and stop at the end of every conveying cycle. Pneu-Con's Vacuum Breaker Valves are solenoid controlled and pneumatically operated.
Additionally, pneumatic conveying systems can be either negative or positive pressure systems. Negative pressure systems suck the material through the lines, while positive pressure systems blow, or push, material down the line. The choice between negative and positive type systems is dictated by factors other than material …
Keep two concepts in mind when considering the use of pneumatic conveying. First, the system pressure decreases along the length of the conveying pipe. This means that the specific volume of the gas increases as does its velocity. These factors limit the conveyance length. Second, there is a minimum velocity needed to carry the …
