In the field of drying powder conveying, achieving efficient, dust-free, and low-energy material transfer has always been a key focus of the industry. Head Powder tailored a negative pressure dilute phase conveying project for dried powder for a company in Jinan, Shandong, successfully solving the conveying challenges in high-dust and high-wear scenarios, providing a reusable technical path for similar projects.

Case Summary

The project is located in Jinan, Shandong, mainly processing dried powdered materials, and is designed using a negative pressure dilute-phase pneumatic conveying system. Head Powder is responsible for the entire process from solution design, equipment manufacturing to installation and commissioning. After the system is put into operation, it continues to operate and has earned full recognition from customers.

Customer pain points

At the initial stage of the project, the client faced the following main challenges:

• Dried powder has fine particle size and is prone to dust generation. Traditional mechanical conveying methods cause dust to spread on site, affecting the working environment and personnel health;
• Materials have slight hygroscopicity and are prone to blockages and arching during transportation, with frequent shutdowns and cleaning affecting production efficiency;
• The original conveyor system consumed high energy, operating costs continued to rise, equipment wear was severe, and maintenance frequency and costs remained high.

Product advantages

To address these pain points, Head Powder offers a comprehensive solution for negative pressure dilute-phase pneumatic conveying, with main features including:

• Fully enclosed negative pressure operation:The system uses full-process negative pressure suction, with pipeline pressure below atmospheric pressure, preventing dust leakage and achieving dust-free transportation, significantly improving the on-site environment.
• Smooth and low-consumption conveying:Dilute phase conveys materials mixed evenly with airflow, with moderate flow rates, reducing pipeline wear and material breakage; At the same time, fan selection and pipeline layout are optimized, reducing energy consumption by about 15%-20% compared to traditional systems.
• Anti-blockage and anti-arching design:Equipped with a dedicated throat gas replenishment device and fluidized bed tailored to the characteristics of dried powder, eliminating risks of material accumulation and arching, and supporting continuous and stable operation.
• Intelligent control and easy maintenance:Integrated PLC automatic control system for real-time monitoring of conveying pressure, flow, and other parameters, with automatic abnormal alarms; The modular structure facilitates routine maintenance and reduces unplanned downtime.

Since delivery, this conveyor system has maintained low failure rates and high conveying efficiency, helping customers achieve both clean production and cost reduction and efficiency improvement. Head Powder will continue to focus on optimizing and innovating pneumatic conveying technology, providing reliable solutions for more material handling scenarios.
