Shandong Rizhao Masterbatch Powder Anti-Static Dust-Free Conveying Project

Pneumatic conveying technology plays an important role in the powder processing industry, especially for materials like masterbatch powders that are high in added value, prone to static electricity, and require extremely high cleanliness, where conveying efficiency and safety must be balanced. This article takes a company's masterbatch pneumatic conveying project as an example to provide a detailed analysis of the anti-static dust-free pneumatic conveying solution implemented in Rizhao, Shandong.

Case Summary

A certain company specializes in the production of masterbatch powder, located in Rizhao City, Shandong Province. To improve the automation level of powder conveying and the on-site environmental quality, the company introduced a dedicated pneumatic conveying system. The system is designed and implemented by Head Powder, used to transport masterbatch powder from the raw material silo to downstream processing equipment.

Customer pain points

During the pre-project research, the client raised several urgent issues that needed to be addressed:
1. Risk of static electricity accumulation: Masterbatch powder is prone to static electricity during high-speed transportation, posing a risk of dust explosion;
2. Dust leakage: Traditional open conveying methods cause excessive dust concentrations in workshops, affecting employee health and equipment precision;
3. Pipeline blockage: Fine powder particle size and strong adhesion, frequent pipe blockages in the original system affect production continuity;
4. Flow fluctuation: Manual feeding and simple conveying devices struggle to stabilize the conveying volume, causing downstream process fluctuations.

Product advantages

To address these pain points, Head Powder's anti-static dust-free pneumatic conveying system offers solutions from the following aspects:
• Anti-static design: Pipelines use conductive or anti-static materials combined with grounding treatment to effectively eliminate static generated during transportation;
• Fully enclosed and dust-free: Fully sealed conveying from feed inlet to discharge port, combined with pulse baghouse dust collectors, ensuring workshop dust concentration is below national standard limits;
• Anti-blockage structure: The inner wall of the pipeline is smooth, the elbow is designed with a large radius of curvature, and is equipped with an automatic purging device to reduce material sticking and blockage;
• Highly accurate measurement: Equipped with a weighing feeder and variable frequency adjustment to achieve stable conveying flow control, adapting to different batch production needs.

After the system was put into operation, dust concentration at the customer's site dropped by about 70%, pipeline blockage frequency dropped to less than once a month, static electricity safety risks were effectively controlled, and overall production efficiency improved significantly. In the future, Head Powder will continue to optimize pneumatic conveying technology, providing more powder enterprises with safe, clean, and efficient conveying options.
