In the world of recycling, the quest for innovation never ceases. Our unique Zig-Zag Air Classifier emerges as a beacon of efficiency in separating lightweight contaminants from heavier plastics, a task it performs with remarkable effectiveness, especially in our PET bottle recycling lines. Beyond mere separation, this machine also contributes significantly towards partially drying the material stream, demonstrating a multifaceted utility.

Working Principle:

The essence of the Zig-Zag Air Classifier lies in its ingenious use of air as the separation medium. The mixed material stream is introduced into a sorting chamber where a column of rising air awaits. As the materials mingle and ascend with the gust of air, a separation saga unfolds. The lighter objects, such as paper and plastic labels, find themselves being whisked away through a top exit, while the heavier plastics obediently descend to make their exit through the bottom.

The design might seem simple, but the mechanics are precise, ensuring a seamless separation process that is crucial for the recycling journey of PET bottles and other materials. The air classifier diagram showcases a simplistic yet efficient design that carries out the task of separation and partial drying with commendable efficacy.


  • Effective Separation: The Zig-Zag Air Classifier stands as a guardian against contaminants, effectively separating lightweight impurities from the heavier plastics, ensuring a cleaner material stream for subsequent processing.
  • Partial Drying: Beyond separation, the air classifier also lends a hand in partially drying the material stream, a feature that enhances the readiness of the materials for the next stages of recycling.
  • Versatile Applications: Although a stalwart in PET bottle recycling, the air classifier’s utility extends to other realms where material streams necessitate separation by weight.
  • Space-Efficient Design: The compact design of the air classifier ensures it fits well within your recycling setup without demanding much space, yet delivering optimal separation results.

Beyond the domain of PET bottle recycling, the Zig-Zag Air Classifier is a versatile companion for various applications where material separation by weight is crucial. Its ability to discern and separate based on weight makes it a valuable asset across diverse recycling operations, underscoring its versatility and importance.

In summary, the Zig-Zag Air Classifier is more than just a separation machine. It’s a step towards enhanced recycling efficiency, ensuring that the journey of plastics from waste to reusable material is smoother and more efficient. By including this innovative equipment in your recycling arsenal, you are not merely separating materials; you are elevating the quality and efficiency of your recycling operation, moving a step closer to a greener and more sustainable operational narrative.
