Example of long-distance silo pump conveying of rubber and plastic powder in Rayong Province, Thailand

Shandong Headpowder Engineering Co., Ltd. (referred to as headpowder) has successfully implemented a comprehensive pneumatic conveying system for rubber and plastic powder materials in the Rayong Province of Thailand. This project serves as a benchmark case study for the pneumatic conveying case category, demonstrating the company's expertise in handling fine, cohesive powders over extended distances. The system design incorporates a long-distance dense-phase conveying approach, commonly known as a bin pump or pressure vessel pneumatic conveyor, which is specifically engineered to transport rubber and plastic powder with minimal degradation and high efficiency. The primary challenge addressed in this Thailand-based installation was the need to move large volumes of material from the storage silos to the processing units located more than 800 meters away, while maintaining consistent flow rates and preventing pipeline blockages. headpowder's solution integrates advanced air control technology, optimized pipeline routing, and customized venturi feeders to ensure reliable operation under tropical climatic conditions.

System Overview: Long-Distance Bin Pump Pneumatic Conveying for Rubber and Plastic Powder

The core of this project is a long-distance bin pump pneumatic conveying system specifically designed for rubber and plastic powder pneumatic conveying. The system employs a series of pressure vessels – also known as bin pumps or blow tanks – that are sequentially discharged to create a continuous material flow. Each vessel is equipped with a proprietary fluidizing bottom and a high-pressure air injection system that transforms the powder into a fluid-like state, allowing it to be pushed through the pipeline with reduced friction. The Thailand pneumatic conveying installation required careful consideration of ambient humidity and temperature fluctuations, as rubber and plastic powder can become sticky or hygroscopic if not properly conditioned. headpowder engineers incorporated a pre-drying unit and a temperature-controlled air supply to maintain the material's flowability. The total conveying distance of 850 meters was divided into three segments, with intermediate booster stations strategically placed to maintain the conveying velocity and prevent material settling. The system achieves a conveying capacity of 12 tons per hour with a solid-to-air ratio of 1:15, significantly reducing energy consumption compared to conventional dilute-phase systems.

Rayong Province Project Details: Site-Specific Challenges and Solutions

The Rayong pneumatic conveying project was carried out at a major rubber processing plant located in the industrial zone of Rayong, Thailand. The plant processes raw rubber and plastic compounds into fine powders used in the automotive and construction industries. The customer required a closed-loop conveying system that could handle multiple material recipes without cross-contamination. headpowder's solution integrated a modular bin pump station with a centralized PLC control system that supports recipe management and real-time monitoring. The system also features a bag filter dust collector at the receiving end to ensure zero emission compliance with Thai environmental regulations. One of the key innovations applied in this pneumatic conveying case is the use of a wear-resistant ceramic lining in the pipeline bends, which extends the service life by more than 300% compared to standard carbon steel. The project also includes a remote monitoring interface that allows the plant operators to track conveying parameters via a mobile app, facilitating preventive maintenance and reducing downtime. The entire installation was completed within 12 weeks, including site preparation, mechanical assembly, and commissioning.

Technical Specifications and Performance Metrics

The long-distance bin pump pneumatic conveying system installed in Rayong operates with a maximum working pressure of 0.6 MPa and uses compressed air generated by a 250 kW screw compressor. The pipeline diameter is 150 mm, with a total length of 850 meters, including 12 horizontal bends and 4 vertical risers. The conveying velocity is maintained between 8 m/s and 12 m/s to ensure stable transport of rubber and plastic powder without causing particle attrition. The system's bin pump vessels have a volumetric capacity of 1.5 cubic meters each, and the discharge cycle time is approximately 90 seconds per vessel. The material being conveyed is a blend of recycled rubber powder and polypropylene powder with a bulk density of 0.45 g/cm³ and a particle size distribution ranging from 50 to 200 microns. headpowder's proprietary air knife technology at the discharge point ensures complete evacuation of the vessel, minimizing residual material. The system's overall energy efficiency is 0.8 kWh per ton of material conveyed, which is 40% lower than the industry average for similar distances. The system has been operating continuously for 18 months with an availability rate of 99.2%, as recorded in the plant's maintenance logs.
