During the processing and transportation of PVC resin powder, traditional mechanical conveying methods (such as screw conveying, belt lifting, etc.) often encounter the following issues:

• Severe dust leakage pollutes the workshop environment, affects operator health, and easily triggers dust explosion risks;
• Materials easily adhere or get blocked on pipelines or equipment walls, causing downtime and cleaning and reducing production efficiency;
• Mechanical components exert pressure and friction on materials, causing damage to resin powder particles and affecting downstream product quality;
• Conveying routes are limited, making it difficult to achieve multi-point feeding or long-distance conveying, resulting in insufficient layout flexibility.

These pain points not only increase the company's operational costs but also limit stable capacity growth. Therefore, an efficient, safe, and environmentally friendly conveying solution has become an urgent need for the industry.

Material characteristics: Difficulties in conveying PVC resin powder

As a polymer raw material, the physical properties of PVC resin powder place special requirements on the conveying system:

• Fine particle size and wide distribution:Common particle sizes range from 50~150μm, which easily generate dust swirling;
• Prone to static electricity:During conveying, friction with the pipe wall easily generates static electricity accumulation, increasing the risk of dust explosions;
• Strong moisture absorption:Exposure to humid air tends to clump and affects mobility;
• Low bulk density:Usually at 0.4~0.6g/cm³, more stable airflow support is needed for smooth conveying;
• Average wear resistance:The degree of wear on the conveying pipeline must be comprehensively considered to avoid metal contamination.

To address these characteristics, customized pneumatic conveying systems need to balance anti-static, moisture-proof, low-breakage, and sealing.

Product Introduction: Head Powder PVC resin powder pneumatic conveying system

Head Powder has been deeply involved in the powder conveying field for many years and has launched the "PVC Resin Powder Pneumatic Conveying System," which adopts a fully enclosed pipeline conveying principle and can flexibly select multiple conveying modes such as positive pressure dilute phase, positive pressure dense phase, or negative pressure suction. The system core consists of a feeding device (rotary valve/jet pump), conveying pipelines, separation device (cyclone separation + bag dust removal), and a control unit (PLC intelligent system). Based on the actual production capacity, layout distance, and explosion-proof requirements of the customer's site, we provide customized comprehensive solutions to achieve automated and dust-free transfer from raw material warehouses to production equipment.

Product Advantages: Targeted solutions to customer pain points

To address the customer pain points mentioned above, the Head Powder PVC resin powder pneumatic conveying system offers the following solutions:

• Sealed and dust-free:The entire system operates in a pipeline-sealed manner, preventing dust leakage from the source, meeting environmental protection and occupational health requirements, and reducing the risk of dust explosions;
• Low Breakage Rate:Uses low-speed feeders and optimized pipeline elbow design to reduce shear and impact forces on resin powder particles, resulting in higher material integrity rates;
• Anti-static and moisture-proof:Pipeline materials can be selected with anti-static coatings or sub-conductive materials, and dew point control devices are used to prevent static accumulation and moisture absorption and caking of materials;
• Intelligent Control:The PLC fully automatic control system can monitor conveying pressure, air volume, and material level in real time, automatically adjust operating parameters, reduce manual intervention, and improve stability;
• Flexible layout:Easily enables horizontal, vertical, and multi-angle steering conveying, supporting long-distance (up to 200 meters) or multi-point unloading, adaptable to different plant structures.

Head Powder provides full lifecycle services from solution design, equipment manufacturing to installation and commissioning, and after-sales operation and maintenance, helping users reduce overall operating costs and improve production continuity and product quality.
