Machine Details

Bale Opener

The bale opener is designed to automatically break apart compressed PET bottle bales. It loosens the bottles and spreads them evenly onto the conveyor, ensuring a stable feeding flow for the entire line. By reducing manual labor and preventing material jams, it improves efficiency and protects downstream equipment.

Label Remover

This machine removes bottle labels, especially PVC or PET shrink sleeves, using friction and mechanical action. Effective label removal reduces contamination in PET flakes and increases the recycling quality. The system is durable and designed for continuous operation with minimal maintenance.

Sorting Table

The sorting table is a conveyor platform where workers manually inspect and remove unwanted materials such as metals, PVC bottles, colored bottles, and other non-PET contaminants. By eliminating impurities at this stage, the sorting table ensures that only suitable PET bottles enter the crusher. This improves the safety of the line, protects equipment from damage, and enhances the quality of the final PET flakes.

Crusher

The crusher reduces PET bottles into uniformly sized flakes. Water-assisted cutting prevents overheating, controls dust, and improves washing efficiency. Consistent flake size ensures more effective cleaning in the following stages.

Screw Loader

The screw loader is designed to automatically transport PET flakes or other plastic materials from one processing stage to the next. It uses a rotating screw enclosed in a tube to convey materials steadily and continuously.

Friction Washer

The friction washer uses high-speed paddles to scrub flakes in water, removing glue, labels, and surface dirt. This intensive cleaning step is critical for high-quality recycled PET. It is designed for heavy-duty, continuous use with easy maintenance.

Hot Washer

The hot washer applies heated water and detergent or caustic solution to remove strong adhesives, oil, and stubborn contaminants. It ensures PET flakes meet food-grade or high-purity recycling requirements. Insulated tanks and optimized heating reduce energy consumption.

Washing Tank

The sink-float washing tank separates PET flakes from caps, labels, and polyolefin contaminants (PE/PP) by density. PET sinks while lighter materials float and are removed. This is an essential step to achieve clean and pure PET flakes.

Washing Tank Screw Loader

The washing tank screw loader is installed at the bottom of the sink-float washing tank to automatically convey cleaned PET flakes out of the tank. By using a rotating screw mechanism, it lifts the submerged flakes steadily while allowing excess water to drain back into the tank.

Horizontal Drying Machine

The horizontal dryer removes surface water from PET flakes through high-speed centrifugal drying. By lowering moisture to less than 1%, it prepares flakes for storage or further processing such as pelletizing. Stable drying improves product consistency.

Label Separator

The label separator removes small label fragments that remain after crushing and washing. Using airflow or impact separation, it ensures a higher purity of PET flakes. This step is especially important for bottle-to-bottle recycling applications.

Electric Cabinet

The electric cabinet houses the central control system for the line. It integrates electrical protection, automation, and safety interlocks. With user-friendly operation and monitoring, it ensures stable performance and easy maintenance of the entire system.
