Ningxia Guyuan Fine Chemical Powder Negative Pressure Dilute Phase Conveying Project
At the Guyuan production base of a fine chemical enterprise in Ningxia, it is necessary to complete the sealed conveying of various powdered raw materials. The company originally used manual feeding and mechanical lifting, facing issues such as dust overflow, high material loss, and time-consuming material replacement cleaning. After on-site evaluation and solution design, Head Powder deployed a negative pressure dilute-phase pneumatic conveying system for them, achieving automated, sealed transportation from raw material warehouses to production equipment.
Customer pain points
Customers have long faced the following challenges in powder conveying:
- Dust swirling leads to poor workshop environments and high health risks for employees;
- Manual handling efficiency is low and easily leads to material spillage and waste;
- When switching between different batches, cleaning the conveying pipelines is difficult, posing a risk of cross-contamination;
- Traditional mechanical conveying equipment has a relatively high failure rate, and maintenance costs continue to rise.
Solutions and product advantages
To address these pain points, Head Powder's negative pressure dilute-phase pneumatic conveying solution has the following features:
- Fully enclosed negative pressure conveying: The system maintains a negative pressure state throughout the entire process from the suction port to the discharge point, preventing dust leakage and significantly improving workshop air quality;
- Low airflow and low damage: Uses dilute phase conveying method, allowing materials to move at lower speeds within the pipeline, especially suitable for fine chemical powders that are fragile and wearable, maintaining particle integrity;
- Quick material change design: Equipped with pneumatic switching valves and detachable pipeline sections, reducing cleaning time by about 60% to meet the needs of small-batch production across multiple varieties;
- Stable and normal operation: Key components are made of wear-resistant materials and branded air source treatment elements, ensuring long continuous system operation cycles and reducing unplanned downtime.
Currently, this system has been operating normally at the Guyuan factory for over 18 months, with an average daily powder processing volume increased by 35%, and workshop dust concentrations dropped below national standard limits. Customers have recognized both conveying efficiency and environmental performance.
