Types of PET recycling machinery

With the increasing threat of plastic pollution, PET recycling machinery has become a popular solution to help reduce plastic waste by transforming it into useful products. Various kinds of PET recycling equipment are available to cater to different requirements of plastic recycling.

• Cutting and Crushing Machines:

  Cutting and crushing machines are usually the first stages in a recycling line. They reduce large plastic bottles into smaller, more manageable pieces. The smaller pieces increase the surface area, making it easier for subsequent recycling processes. These machines typically include bottle shredders and granulators.

• Washing & Drying Machines:

  After the bottles have been shredded or granulated, they usually contain labels and residual contaminants that need to be cleaned. Washing and drying machines for plastic recycling will offer multiple washing cycles with different washing tanks to remove these contaminants. Detergent, hot water, and ultrasound are typically used during the washing process. The drying process sometimes combines a wind blower that uses high-pressure air to remove excess moisture from the plastic pieces.

• Air Separation Machines:

  These machines help separate different types of plastic materials. They remove foreign materials like metals or non-recyclable plastics that may have entered the washing process. This is usually done by using a flow of air that pushes lighter materials away from the heavier ones.

• Optical Sorting Machines:

  Optical sorting machines use advanced camera technology to identify and sort various types of plastics. They distinguish between materials based on their color and chemical composition. Once identified, the plastics are ejected into different containers for further processing.

• Extruding Machines:

  The extruding machine's primary function is to melt the sorted plastic materials and mold them into new products, such as plastic pellets. It can create new products, such as furniture, bags, bottles, and t-shirts.

• Granulating Machines:

  Granulating machines work similarly to extruding machines. However, they break down the plastic materials into smaller pieces or granules. The granules are then manufactured into various plastic products.
