Question: What types of pneumatic conveying systems are typically used?
Keywords: pneumatic,conveying,convey,types,dilute,dense,phase
Answer: Essentially, there are two types of pneumatic conveying systems. In dilute phase systems, the solids are suspended in the carrier gas and transported to their destination. In dense phase systems, the solids-to-gas ratio is much higher. The gas in these systems acts more like a piston to push the product to its final destination.Dilute phase systems are more typical than dense phase systems because they can employ positive pressure displacement or a vacuum systm. Dense phase conveying is useful if the product degrades easily (works at lower velocities) or is particularily abrasive.
