Glass fiber reinforced plastic pellets, often called GFRP pellets, are widely used in automotive, electrical, and household products because of their excellent strength and heat resistance. During production, they must be moved from storage silos, dryers, mixers, or granulators to processing machines without contamination or damage. A well-engineered pneumatic conveying system offers the most efficient and reliable way to transfer these pellets through a sealed pipeline, eliminating manual handling and reducing material loss. The system can be integrated with existing drying and mixing equipment to create a complete automated production line.

GFRP pellets have special characteristics that affect conveying design. The glass fibers in the pellets are abrasive to standard pipes, and fibers may become exposed if the pellets are moved at high speed or high impact. Exposed fibers reduce product quality and can cause blockages. Static electricity and moisture can also make the material flow poorly. A successful conveying system must be engineered around these real material properties, not just selected from a catalog.

We design both dilute-phase and dense-phase pneumatic conveying systems for GFRP pellets. Dilute-phase conveying uses high air velocity to suspend pellets in an air stream; it is simple and cost-effective for short and medium distances. Dense-phase conveying uses low velocity and high pressure to push pellets through the line, causing less fiber breakage and pipe wear. Vacuum systems are suitable for unloading silos and bulk bags, while pressure systems can distribute pellets to multiple production lines.

Every custom system is built from reliable components. A rotary airlock valve feeds pellets into the pipeline at a controlled rate. A blower, compressor, or vacuum pump provides airflow and pressure. A filter receiver or cyclone separates pellets from air at the discharge point. The control panel manages sequence and pressure, allowing automatic startup, shutdown, and line clearing. Because GFRP pellets are abrasive, we use wear-resistant pipes, ceramic-lined elbows, and impact-resistant bends to reduce maintenance. Dust-tight connections and cartridge filters keep the plant clean and protect workers.

These systems are used in automotive injection molding, electrical enclosures, pipe fittings, and chemical processing. They deliver GFRP pellets to molding machines and protect dimensional stability. The main benefits include lower labor costs, improved safety, reduced waste, consistent material quality, and high efficiency. Because the pipeline is fully enclosed, there is no dust leakage or contamination. The system also saves floor space by running pipes overhead or through existing walls.

Every conveying solution is customized to your material properties, capacity, site layout, and budget. We test pellets in our laboratory, provide a detailed layout and component list, and support startup, maintenance, and upgrades.
