A: Suspension Flow Conveying
The material conveying speed is higher than the suspension velocity, and the material flows in a suspended state within the pipeline. The concentration ratio is low. This conveying method is suitable for low-pressure, dilute-phase, short-distance conveying.

B: Plug Flow Conveying
The material conveying speed is approximately equal to the suspension velocity, and the material moves in a plug-like state within the pipeline. The concentration ratio is moderate. This conveying method is suitable for medium-pressure, long-distance conveying.

C: Dense-Phase Flow Conveying
The material conveying speed is lower than the suspension velocity, and the material in the pipeline is cut into plugs by pulse air valves and pneumatic pressure. The pressure difference before and after the material plugs acts as the driving force. The concentration ratio is high. This conveying method is suitable for high-pressure, dense-phase, long-distance, low-speed conveying.
