What is a Nitrogen closed-loop positive pressure conveying system? Powder pneumatic conveying specifications, models, and parameters

Nitrogen closed-loop positive pressure conveying systemmainly uses the airflow generated by the fan to transport materials along the airflow direction in the closed conveying pipeline.，the principle is simple.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. In the process of transportation, gas-solid separator (such as dust collector) is used to separate materials from air to ensure the quality of transported materials.，widely used in metallurgy, chemical plant, pharmaceutical factory, medicine, grain processing and other fields，be loved by our customers.。
