Introduction:
Frequent pipe blockages during transportation, high material damage rates, and persistently high equipment maintenance costs? The rotary valve dilute phase negative pressure pneumatic conveying system centers on sealed negative pressure conveying, addressing dust leakage and pipeline blockages at the source, enabling powder materials to achieve low crushing, high cleanliness, and normal operation.
Frequent pipe blockages during transportation, high material damage rates, and persistently high equipment maintenance costs? The rotary valve dilute phase negative pressure pneumatic conveying system centers on sealed negative pressure conveying, addressing dust leakage and pipeline blockages at the source, enabling powder materials to achieve low crushing, high cleanliness, and normal operation.
The rotary valve dilute phase negative pressure pneumatic conveying device is a negative pressure conveying device developed by Head Powder specifically for powdered and granular materials. It uses a rotary valve as the feeding and air locking element, utilizing a negative pressure airflow generated by a Roots blower or vacuum pump to draw the material from the nozzle into the pipeline and complete gas-solid separation through a separator. The system is suitable for long-distance, multi-point conveying of granular and powdered materials, and can flexibly connect to downstream processes such as batching and packaging to achieve automated continuous operations.
Negative pressure sealed conveying: Full-pipeline negative pressure operation, no dust leakage, meeting environmental protection and cleanroom requirements.
Rotary valve delivers more accurate feeding: Feeding volume is controlled through variable frequency speed regulation, ensuring uniform material flow and less prone to clogging.
Low energy consumption and high efficiency: The dilute phase conveying gas velocity is reasonable, with low unit energy consumption, minimal wear on pipelines, and extended equipment lifespan.
Modular design: Flexible combination of nozzles, pipelines, separators, dust collectors, and other components according to site space and process requirements.
Intelligent control: supports PLC automatic control, real-time monitoring of pressure and material level, reducing manual intervention.
The rotary valve dilute phase negative pressure pneumatic conveying is a customized product, with prices calculated comprehensively based on conveying distance, material characteristics, conveying volume, site layout, and other factors. Head Powder provides free technical solutions and quotations. We welcome you to provide material parameters and process requirements for exclusive solutions.
