Flexible Screw Conveyor for Plastic Pellets

Tuesday February-24 2026  17:56:44

Flexible Screw Conveyor for Plastic Pellets is a continuous conveying system used to transport plastic granules. It handles feeding, transfer, batching, and packaging, delivering granules from silos, bags, and crushing equipment to extruders, injection molding machines, and mixers, ensuring stable production line operation. It can convey 1–20 tons of material per hour, with the conveying capacity adjustable by pipe diameter, rotation speed, and material density.

The Flexible Screw Conveyor for Plastic Pellets can be installed horizontally, inclined, and vertically. Horizontally, it can convey up to 15 meters, and vertically, it can lift up to 8 meters, navigating complex routes by bypassing equipment and building obstacles. Common motor power ranges from 0.75kW to 4kW; lower power motors are suitable for single-unit feeding, while higher power motors are suitable for long-distance, high-flow conveying. Pipe diameters are available in Φ100mm, Φ120mm, Φ140mm, and Φ160mm; smaller diameters are suitable for small-volume feeding, while larger diameters are suitable for large-volume conveying. It is compatible with common plastic granules such as PP, PE, ABS, and PVC.

Features of the Flexible Screw Conveyor for Plastic Pellets

The Flexible Screw Conveyor for Plastic Pellets takes into account the characteristics of plastic granules. Because plastic granules are highly fluid, easily breakable during processing, and may carry static electricity, the flexible screw conveyor uses a shaftless helical spring structure. During operation, it gently propels the material, preventing strong scraping of the granules and controlling the breakage rate to within 1%, keeping the raw material intact. Its conveying pipe is made of flexible high-molecular-weight PU or PE material, with a smooth and wear-resistant wall, reducing material friction and minimizing granule adhesion caused by frictional heat. The entire conveying process is completed within a closed pipeline, preventing plastic granule dust from escaping, resulting in a cleaner workshop environment. It is suitable for producing various plastic products with requirements regarding black spots and impurities.

Price of Flexible Screw Conveyor for Plastic Pellets

The price of the Flexible Screw Conveyor for Plastic Pellets varies depending on the pipe diameter, length, material, motor, and customization requirements. The basic model uses carbon steel, with a pipe diameter of Φ100 to Φ120 mm, a length of 3 to 5 meters, and a motor power of 0.75 to 1.5 kW. Each unit costs approximately $400 to $850, suitable for small processing plants using a single unit. The standard model is available in both carbon steel and stainless steel, with a pipe diameter of Φ140 to Φ160 mm, a length of 5 to 10 meters, and a motor power of 2.2 to 3 kW. The price ranges from $850 to $1700 per unit, sufficient for continuous conveying of plastic granules in medium-sized production lines. Custom models, made entirely of stainless steel, equipped with explosion-proof motors, supporting variable frequency speed control, or requiring longer conveying distances, are more expensive, generally ranging from $1700 to $3500 per unit, and are mostly used in plastic processing scenarios with high hygiene and safety requirements.

Flexible Screw Conveyor for Plastic Pellets Application Case

In a plastic modification plant, multiple Flexible Screw Conveyors for Plastic Pellets were used to transport mixed PP and ABS granules from the mixing tank to the finished product silo in the packaging workshop. This conveyor system is 12 meters horizontally, 4 meters vertically, and has a pipe diameter of 114 mm. Equipped with a 4 kW motor, it can transport 8 tons of material per hour. After installation, the problem of numerous columns and limited space in the plant was solved. It operates with low noise and prevents dust leakage, improving the working environment. On the pipe extrusion production line, a small flexible screw conveyor is installed above each extruder, directly drawing material from the central feeding system to continuously and stably supply raw materials to the production equipment.

Applications of the Flexible Screw Conveyor for Plastic Pellets

The Flexible Screw Conveyor for Plastic Pellets is suitable for most plastic processing scenarios, offering good compatibility with materials and the environment. In terms of materials, it can convey dry, free-flowing virgin materials, recycled materials, and modified granules, with a moisture content controlled below 0.5%, reducing material sticking and clogging. It can handle material temperatures from ambient to 60°C, meeting daily plastic granule conveying needs. Environmentally, it can be used indoors or in semi-open areas, with ambient temperatures ranging from -10°C to 40°C, humidity not exceeding 85%, and no condensation. Installation is flexible, allowing for fixed or mobile installation, ground placement or overhead mounting, suitable for layouts with limited space, multi-story plants, and cross-equipment conveying.

The Flexible Screw Conveyor for Plastic Pellets offers advantages in terms of operating costs, operational status, and overall investment. It can be routed according to site conditions, providing a smooth conveying process with minimal plastic granule loss. Daily maintenance is simple, and it adapts to the state of the plastic granules and production rhythm. The equipment is available in various specifications, with suitable models available for small processing plants and large automated production lines. After use, it can improve conveying, reduce material waste, create a cleaner workshop environment, and simplify production management.
