Most Vacuum Conveying System transfer product based on a timed interval to the vacuum receiver.
Introduction to Pneumatic Conveying of Solids
Pneumatic conveying is the movement of solids through pipe using gas (usually air) as the motive force. It differs from hydraulic or slurry conveying in that the gas expands continuously along the pipe length. The flow regime in the pipe depends greatly on the ratio of solids to gas and the particle characteristics. Why use pneumatic conveying to.
VF-Broschüre 2016 US

Answers to Eight Common Questions about …
A pneumatic conveying system transfers powders, granules, and other dry bulk materials through an enclosed pipeline. The motive force for this transfer comes from a combination of pressure differential and the flow of a gas, such as air or nitrogen. (For simplicity, we'll call the gas "air" in this article.) The system's basi…See more on nol-tec
