There are three types of pneumatic conveyors, which are defined according to the type of material they can move as well as the source of their airflow.
Dilute Phase Pneumatic Conveyors
It utilizes high-velocity, low-pressure streams of air that fluidize fine particles. The material is pushed by a screw feeder directly inside the conveying line and then sent through an air mover at high speeds.
Dense Phase Pneumatic Conveyors
This type of conveyor uses low velocity and high pressure and is suitable for products that are prone to breaking. The material is first loaded into a pressure vessel, from where it’s forced into the conveying line by high pressure and moved to its destination.
Semi Dense Phase Pneumatic Conveyors
It’s essentially a middle point between the two other systems and thus offers the qualities of both types. They have an air mover and are pressurized, so they can move bulk material at a slightly higher speed while still protecting it.
