Using air kinetic energy as a conveying medium, materials are transported in pipelines at relatively high speeds and in a dispersed and suspended state. The conveying pressure can generally be adjusted within the range of several thousand pascals to several hundred kilopascals according to different working conditions.　　Using gas dynamic pressure, the material advances at a high speed in the conveying pipeline (8m/s-25m/s), and the conveying pressure gradually decreases along the conveying pipeline;　　Continuous conveying, the conveying flow state, conveying pressure and speed, and material gas ratio remain basically stable;　　In certain circumstances, the conveying distance is shorter than that of the positive pressure dense phase and longer than that of the negative pressure dilute phase;　　During the conveying process, the outlet air temperature of the Roots blower is relatively high;　　In order to prevent air leakage, the system needs to be equipped with a well sealed rotary feeding valve/rotary valve/star shaped discharge valve/shut-off fan discharge device.　　Positive pressure conveying rotary valve/pneumatic rotary valve is mainly used for conveying chemical, food, medicinal materials, lithium batteries, and plastic raw materials.
