4、Advantages of Nitrogen closed-loop positive pressure conveying principle

Nitrogen closed-loop positive pressure conveyingat work,Compressed air or other gases are passed through the air supply device to generate airflow, forming a certain airflow speed and pressure. Subsequently, the material is sent into the conveying pipeline through the feeding device, and under the action of the airflow, the material particles are suspended in the airflow or flow along the pipeline in groups. This gas-solid two-phase flow state enables materials to be transported to the target position along the pipeline.，is a Nitrogen closed-loop positive pressure conveying newly developed by hyde。
