Pneumatic conveying systems are suitable for a wide range of powder and granular materials in chemical production. These include various polyolefins such as PP, PE, POE, EVA, as well as chemical raw materials, additives, catalysts, intermediates, and finished products.

Due to the corrosive nature of many chemical substances, our conveying systems utilize corrosion-resistant materials such as stainless steel and engineered plastics. Surface treatments are also applied to enhance durability and ensure long-term, stable operation in harsh environments.

For flammable or explosive chemicals, our systems use inert gases such as nitrogen as the conveying medium to eliminate combustion risks. Optional gas recovery units enable collection, pressurization, and reuse of inert gases, reducing operational costs. Additional safety features include explosion-proof instruments, electrostatic grounding, safety valves, and rupture discs to ensure safe and reliable operation.

Dust collectors and dedusting units are critical for preventing contamination and maintaining product quality. Baghouse dust collectors minimize emissions from exhaust air, protecting both the environment and workplace air quality. Dedicated dedusting units remove fine dust, streamers, and fiber-like contaminants from loose bulk-solids, making them ideal for polymer reprocessing applications.

Efficiency can be enhanced by optimizing system layout and design:

• Avoid bottlenecks that restrict material flow.
• Ensure all equipment is correctly sized with appropriate technical specifications.
• Simplify conveying paths to reduce sharp bends and flow restrictions.
• Use anti-blocking devices to reduce the risk of clogging and ensure uninterrupted conveying.

There are two main types of pneumatic conveying: pressure conveying and vacuum conveying. Pressure conveying pushes material through the pipeline using compressed air, while vacuum conveying draws material toward the destination. Both methods are suitable for plastic pellet transfer. The choice between them depends on your plant layout, material properties, and system requirements. Additionally, it is crucial to determine whether to use dilute-phase or dense-phase conveying, depending on factors like particle fragility, flow rate, and conveying distance.

Yes, pneumatic conveying is well-suited for handling delicate resin materials. Because the process involves minimal mechanical contact with the material, it helps reduce the risk of degradation or damage during transfer. This makes it ideal for preserving the quality of sensitive resins throughout the production process.
