PBAT (polybutylene adipate terephthalate) is a biodegradable polyester widely used in film blowing, shopping bags, and compostable packaging. In modern production plants, handling PBAT pellets efficiently and safely is essential to maintain product quality and reduce manual labor. Pneumatic conveying is a proven method that moves pellets through enclosed pipelines using air pressure or vacuum, offering a dust-free, flexible, and highly automated solution for PBAT material transfer.

Pneumatic conveying for PBAT pellets offers multiple advantages. It fully encloses the material flow, preventing moisture, contamination, and dust. The system requires minimal floor space and can be routed around existing equipment. It also supports gentle handling at low velocity, reducing pellet breakage and fines generation while preserving resin quality. Unlike mechanical conveyors, pneumatic systems have fewer moving parts, lowering maintenance costs.

A complete PBAT pellet pneumatic conveying system includes a rotary airlock or vacuum feeder, a blower or vacuum pump, a pipeline with smooth bends, and a cyclone separator with bag filter. Each component is carefully sized to match the required conveying rate, distance, and elevation. Proper sizing of the blower and filter is critical to prevent energy waste and ensure continuous operation.

Every production facility has unique requirements. We offer fully customized PBAT pneumatic conveying solutions based on material properties, conveying distance, throughput, and plant layout. Our engineers evaluate bulk density, particle size, and flowability before designing the system, ensuring reliable operation and low energy consumption. We also perform on-site trials to verify system performance before final commissioning.

Both dense phase and dilute phase conveying can be applied for PBAT pellets. Dilute phase systems use high air velocity to suspend pellets, suitable for short distances and high capacities. Dense phase systems operate at low velocity and high pressure, pushing slugs of material gently through the pipeline, which significantly reduces pellet degradation and dust.

The equipment is manufactured from stainless steel or carbon steel with appropriate surface treatment. Stainless steel is recommended for high-purity applications. All contact surfaces are smooth and free from sharp edges to prevent material accumulation, and the systems comply with international safety and environmental standards. Optional accessories include rotary valves, diverters, and level sensors.

Advanced PLC and HMI control panels are equipped on modern PBAT pellet conveying systems. They monitor pressure, air flow, and motor status in real time. Operators can adjust conveying speed and sequence via a touch screen. Automatic start-stop and alarm functions prevent blockages and equipment damage, and the system can be integrated into plant automation networks.

These systems are widely used in biodegradable resin production, film manufacturing, masterbatch factories, and plastic recycling. They are also suitable for PLA, PHA, and PBS pellets. The flexible design supports multiple pick-up and discharge points, enabling one system to serve several processing lines and reducing overall equipment cost. Custom engineered layouts can minimize bends and vertical lift, further protecting the pellets.

We provide complete installation, commissioning, and after-sales support for every system. Our technical team supervises installation and trains operators. We also offer preventive maintenance, spare parts, and system upgrades. With extensive project experience, we ensure your conveying line operates at peak performance from day one.
