During the processing and transportation of recycled plastic pellets, enterprises often face issues such as dust accumulation, harsh workshop environments, and low manual handling efficiency. Traditional mechanical conveying methods easily cause particle damage and material residues, and are difficult to adapt to production switching between multiple batches and varieties. In addition, high energy consumption and frequent pipeline blockages during long-distance transportation seriously affect production line continuity, becoming a key bottleneck restricting capacity improvement.

Material characteristics

Recycled plastic pellets have irregular shapes and sizes, and some materials contain fine powder or fiber impurities. Friction easily generates static electricity, which adheres to the tube wall and hinders conveyance. They have low density and are prone to moisture, so strict control of air velocity and gas-solid ratio during sealed transport is necessary to prevent material damage or caking. Some recycled materials also carry residual heat and volatile odors, requiring the system to have sealing and heat dissipation capabilities.

Product Introduction

Head Powder has launched a pneumatic conveying system for recycled plastic pellets, using positive pressure dilute phase or dense phase conveying methods, with customized solutions based on material characteristics and on-site conditions. The system consists of air source equipment, feeders, conveying pipelines, dust separation and removal devices, and electrical control modules, achieving full-process closed-loop transportation from silos and crushers to pelletizers and packaging machines. The pipeline uses wear-resistant stainless steel or polymer lining materials, combined with optimized elbow design, effectively reducing material residue and equipment wear. The electrical control system supports PLC automatic adjustment and remote monitoring, allowing seamless integration with existing MES or DCS platforms.

Product advantages

To address customer pain points, this solution offers the following solutions: 1) Fully enclosed negative pressure/positive pressure conveying to suppress dust leakage from the source, improving the workshop environment; 2) Low air velocity and high-concentration conveying design reduces particle collision and breakage, improving finished product yield; 3) Modular structure supports quick assembly and disassembly, adapting to switching between multiple material types; 4) Intelligent anti-blockage control system monitors pipeline pressure in real time, automatically backblows to clear blockages, facilitating continuous production; 5) Energy consumption is more than 20% lower than traditional mechanical conveying, gas volume is matched as needed, and operating costs are controllable.
