Our pneumatic conveying solution for recycled plastic pellets is a comprehensive, custom-engineered system designed to transport recycled resin pellets safely, efficiently, and without contamination. We specialize in both dilute-phase and dense-phase pneumatic conveying, tailored to the unique handling characteristics of post-industrial and post-consumer recycled plastics. As a dedicated manufacturer and solution provider, we deliver complete systems including air blowers, rotary feeders, transfer pipelines, cyclone separators, bin vents, and PLC-based control panels.

Recycled plastic pellets often have irregular particle shapes, varying bulk density, and residual dust or fines. Unlike virgin pellets, they may be more delicate and prone to thermal or mechanical degradation. Our pneumatic systems use adjustable air velocity and low-pressure conveying to minimize abrasive wear and product breakage. Whether your material is PET, HDPE, PP, LDPE, PVC, ABS, or nylon, we configure the system with the correct pipe diameter, bend radius, and air-to-material ratio to ensure smooth flow.

We provide two main conveying modes. Dilute-phase pneumatic conveying is ideal for moderate distances and capacities, using high air velocity to suspend particles in the air stream. Dense-phase conveying operates at lower velocity and higher material-to-air ratio, suitable for friable or abrasive recycled pellets, longer distances, or fragile particles. Our engineers analyze your material properties and site layout to recommend the optimal mode, avoiding pipeline blockage and excessive energy use.

The standard system components include a positive displacement blower or vacuum pump, a material pickup point or hopper with a rotary airlock, a conveying pipeline with wear-resistant bends, a receiving vessel with a cyclone separator and bag filter, safety relief valves, and a control system. We also integrate metal magnets, de-dusting classifiers, and material conditioners if required. Each component is selected from established industrial brands, ensuring reliable operation in continuous production environments.

Our custom designs consider every relevant factor: conveying distance, vertical lift, number of delivery points, throughput demand, available space, and existing equipment integration. We provide both single-line and multi-line systems, with manual or automatic switching between silos, blenders, or process machines. The PLC system enables precise batch weighing, sequence start-up, and remote monitoring. Alarm interlocks prevent overpressure, fan overload, or filter blockage, protecting your equipment and operators.

For recycled plastic pellet conveying, dust control is crucial. The regeneration process often leaves dust and fines that can cause explosions or quality issues. Our closed-loop pneumatic conveying systems prevent dust escape and incorporate explosion relief panels and grounding for static electricity. Filter receivers and cartridge filters efficiently separate air and material, ensuring clean air exhaust. This meets strict occupational safety and environmental standards while maintaining a clean plant floor.

Energy efficiency is another advantage. By optimizing the pipe layout and using variable frequency drives on blowers, we reduce power consumption compared with traditional mechanical conveyors. Also, because pneumatic conveying is fully enclosed, there is no material loss, minimal contamination, and low maintenance.

Our field service team supports you from installation to commissioning, operator training, and after-sales maintenance. We also provide upgrading solutions for existing conveying lines, including replacement of worn pipes, new rotary valves, or advanced controls. We have delivered successful projects for plastics recyclers, pellet producers, compounders, and large processing plants. Our goal is to provide a turnkey system that increases your production efficiency and product quality.
