Application and Introduction
Powder dilute phase pneumatic conveying system, also known as lean phase pneumatic conveying system, is a mature and widely used pneumatic material conveying technology in modern industrial production. The system essentially adopts low-pressure and high-velocity airflow to realize continuous material transportation. It features a low material-to-air ratio, allowing materials to be stably suspended in the airflow for suspension flow conveying. This conveying method has strong compatibility with materials, and is basically not restricted by particle size, particle shape and material density. It is especially suitable for fine powder materials with low bulk density and low air retention performance.
As a professional industrial conveying solution, our dilute phase pneumatic conveying system supports customized design according to on-site process requirements and different industrial scenarios. With more than 20 years of industry manufacturing experience, we are a leading manufacturer of dilute phase and lean phase pneumatic conveying equipment. The system is widely matched with bulk bag loading systems, realizing integrated operations of powder conveying, transferring and bulk packaging loading, which greatly improves the automation level of factory powder processing.
Types of Lean Phase Conveying System
The positive pressure dilute phase pneumatic conveying system operates under working pressure higher than atmospheric pressure. Compared with vacuum negative pressure conveying systems, it has larger conveying capacity and is more suitable for medium-distance bulk material conveying scenarios. The system is equipped with professional diverter valves, which can easily realize sequential conveying and multi-point feeding of materials to multiple destination receiving points, meeting the production demand of one-line multi-point distribution.
In addition, the positive pressure system supports multi-feeding-point feeding into a single public conveying pipeline. Through reasonable air volume matching and supporting special rotary air lock valves, it ensures stable air pressure in the pipeline, uniform material feeding and no material backflow, realizing efficient and stable continuous conveying operation.
