This is a high-efficiency material pressure pneumatic system, utilizing a Roots blower as the power generator and a rotary feeder as the core feeding facility. The system is engineered for low-pressure environments, featuring short-distance transporting capabilities and exceptionally reliable conveying performance.

It is perfectly suited for conveying materials from a single source to multiple destinations, effectively integrating drying and classification functions. Due to the positive pressure maintained within the system, external contaminants such as air or rainwater are prevented from entering, ensuring material purity even if minor apertures exist in the piping connections.
