Product Overview
• The Big Label Separator Barrel is an important pre-treatment machine in PET bottle recycling lines. It uses a combination of high-speed airflow and gravity to separate lightweight contaminants, including bottle labels, dust, and fine fibers, from heavier PET flakes.
• Material is evenly conveyed into the separator barrel, where the blower generates an airflow that carries lightweight contaminants away from the heavier plastic flakes. The separated materials are discharged through their respective outlets.
• By reducing label and light-contaminant content, the machine helps improve the cleanliness and consistency of PET flakes before downstream processing.
• It is commonly installed in two positions: before the hot washing pot to reduce label contamination entering the washing section, and after the high-speed centrifugal dryer to remove residual lightweight labels and fibers.
Light labels and contaminants going into the hot washing pot cause contamination and destabilize downstream processing.
Pre-Hot-Washing Separation. Install the separator before the hot washing pot to remove light labels and impurities in advance.
PET flakes still carry leftover labels, dust and fibers after dewatering, which disturbs color sorting and further processing.
Post-Drying Separation. Set the separator after the centrifugal dryer for secondary impurity removal.
Key Features

Questions
It separates lightweight labels, dust, and fine fibers from heavier PET flakes using airflow and gravity, helping improve the cleanliness of the recycled material.
It can be installed before the hot washing pot to reduce incoming label contamination, or after the high-speed centrifugal dryer to remove residual lightweight contaminants. The optimal position depends on your process and material condition.
Blower selection depends on the separator barrel diameter, required airflow, processing capacity, and material characteristics. Our team can recommend a suitable configuration based on your production requirements.
The machine helps separate lightweight labels, but complete label removal cannot be guaranteed. Results depend on label type, particle size, moisture, airflow, and the overall washing-line configuration.
Yes. It can be integrated into an existing line before hot washing or after centrifugal drying. Please provide your current process flow, target capacity, and material condition so we can recommend the appropriate configuration.
