Types of Pneumatic Conveying Systems

Semi-Dense Phase Pneumatic Conveyors. This type of conveying system utilizes a medium velocity airflow to transport materials. To put it simply, it’s essentially the middle ground between dense and dilute pneumatic conveyors. They move faster than the former but are still usable with some abrasive, friable materials like cement.

Understanding dense-phase conveying I Fundamentals

2019-7-17  conveying. Dilute-phase conveying is the most common of these two systems, due in part to its relatively straightforward design. If designed correctly, a dilute-phase conveying system can provide reliable and flex-ible service1. However, dilute-phase conveying requires a lot of gas and operates at relatively high gas and solids velocities.
