PP PE Plastic Film Densifying Washing Line

At our company, we specialize in delivering efficient and sustainable solutions for plastic film recycling. We understand the importance of preserving the environment while addressing the growing demand for plastic pellets. Our comprehensive plastic film washing line is expertly designed to handle polypropylene (PP), polyethylene (PE), and a diverse range of other plastic films. With state-of-the-art technology, our fully automated line incorporates a series of strategically arranged recycling machines, optimizing efficiency and minimizing waste.

Custom Plastic Film Washing Line Solutions

Our standard plastic film washing line, with input capacities ranging from 500kg/h to 3000kg/h, is customizable to meet larger recycling needs. We provide tailored setups for clients requiring higher capacity, utilizing additional machinery to ensure we meet unique demands.

Environmentally Conscious Recycling

Our turnkey solution effectively recycles loose or baled plastic film into plastic pellets, significantly reducing the carbon footprint of plastic waste. By recycling plastic film instead of sending it to landfills, we contribute to a healthier environment for future generations.

Working Principle

The entire plastic film washing line is controlled via a central electric control panel and cabinet. Each piece of equipment is connected using conveyors.

  1. Plastic Shredder Machine:

    As long pieces of plastic film easily tangle (imagine saran wrap) and clogs conveyors and rotary-based machines, the first step is to cut the plastic film into smaller pieces using a plastic shredder machine. The resulting plastic pieces from the plastic shredder is around 1-5 inches.

  2. Plastic Granulator:

    The plastic granulator cuts the plastic film into even smaller pieces approximately 10-20mm in size. With water constantly injected into the cutting chamber, our wet granulation process also “pre-treats”and partially cleans the plastic film before moving onto the next machine.

  3. Friction Washer:

    A high-power washing machine, our cold water friction washers spins at nearly 1,000 rotations per minute. As the PP /
    PE films enters the friction washer, the plastic film rubs against each other at high speeds getting rid of hard to remove contamination. At the same time, any paper and cardboard is broken down into fibers and removed. While one friction washer isstandard, various washing plants have requested a secondary friction washer to ensure thorough cleanliness.

  4. Sink Float Separation Tank:

    Using water as a medium, materials that float are separated from materials that sink. In the case of plastic film recycling, PP and PE films will float while heavier contamination such as dirt, sand, glass, metals, other plastics will sink. A screw conveyor at the bottom of the sink float separation tank removes the contamination. While separation is one aspect of this apparatus, a secondary function is to further clean the plastic film.

  5. Centrifugal Dewatering Machine:

    The first step in the drying process, our centrifugal dewatering machine uses centrifugal force to remove a large portion of water within the plastic film before moving forward onto the thermaldryers. As thermal dryers use heat to dehydrate water, it requires more energy consumption during operation. Hence, the use of the dewatering machine is beneficial in savings for long run operations costs.

  6. Screw Press Dewatering Machine:

    An optional piece of equipment, the screw-press dewatering machine is a more advance version of the standard dewatering machine. Instead of using centrifugal force to remove water from the plastic film, the screw press squeezes the water out via high pressure. This machine can actually take the place of both the dewatering machine and thermal dryers.

  7. Thermal Dryer +Cyclone Separator:

    The clean plastic film is vacuumed out of the dewatering machine and into the thermal dryer system where it’ ll travel down a series of stainless steel tubes mixing with hot air. The remaining moisture is dehydrated in this process which ends with a cyclone separator. The cyclone separator allows the plastic film to mix with a fresh stream of cold air which prepares it for storage into the product silo. The cyclone separator is also effective in removing fines and such dust.

  8. Product Silo:

    A storage tank for the clean, dry pieces of plastic film.

  9. Plastic Pelletizing Machine:

    The final step in plastic film recycling and maybe the most important, the clean film needs to be processed into plastic pellets before it can be used in production. To do so, we offer a specialized plastic film water ring pelletizer system that produces beautiful round plastic pellets.
