A pneumatic conveying system is a device that utilizes the energy of air to transport materials through enclosed pipelines.
It consists of a material feeding mechanism, a conveying pipeline, and a material discharge mechanism.
Pneumatic conveying systems are classified into negative-pressure and positive-pressure conveying based on the method of pressure generation within the system; they are classified into dilute-phase and dense-phase conveying based on the mass concentration ratio of the solid-gas two-phase flow in the pipeline. Dense-phase conveying can be further subdivided into dense-phase dynamic-pressure and dense-phase static-pressure conveying.
