Positive Pressure Conveying System
A positive pressure conveying system is an industrial device that uses compressed air as the power source to transport granular, powdered, or lump materials through closed pipelines under conditions above atmospheric pressure. Its core feature lies in utilizing high-pressure gas to propel materials, enabling efficient and clean automated conveyance. It is widely applied in industries such as power generation, cement, chemicals, and food processing.
The system achieves efficient and enclosed industrial transport by driving materials with high-pressure gas. Selection of the system requires comprehensive consideration of material characteristics, conveying distance, and energy consumption. In sectors like cement and chemicals, its advantages in long-distance and automated transportation are particularly notable. However, regular maintenance is essential to ensure operational stability.
Applications
Widely used in the power, building materials (such as cement), chemical, and food processing industries, it is suitable for the automated, enclosed conveying of granular, powdered, and lumpy materials.
