Description

Plastic film washing lines play a crucial role in the recycling of plastic films. This washing line comprises a series of specialized equipment designed to clean contaminated plastic films, such as LDPE, making them suitable for pelletizing—the process of transforming plastic into granules or recycled pellets that serve as raw materials for new product manufacturing.

The washing line typically includes fundamental components like shredders or granulators, high-speed friction washers, gravity separation tanks, and drying systems. Material transitions between machines occur via belt or screw conveyors and vacuum hosing. While various innovative models exist, their fundamental functions are consistent. Additional machinery, including rotating trommels or air classifiers, can enhance contamination removal, improving the washed films' quality.

Shredders

Industrial shredders are robust, low-speed, high-torque machines featuring shear blades of various shapes that cut and shred materials. Their design enables them to effectively process large volumes of feedstock into smaller pieces, ensuring minimal dust generation. Shredders are categorized based on their number of shafts; options include single, dual, and quad-shaft models, catering to specific applications such as:

1. Rubber or tire recycling.
2. Metal recycling.
3. E-waste recycling.
4. Destruction of sensitive items, such as documents and pharmaceuticals.
5. Wood recycling for particle board production.
6. Size reduction in wastewater treatment processes.
7. Destruction of various bulky materials.

In the case of automated plastic film recycling, shredders accommodate batch feeding of large film bales, standard practice in recycling centers. These bales, compact bundles of plastic film, significantly reduce transportation costs and storage needs.

Granulators

Plastic granulators operate at higher speeds, transforming shredded material into smaller flakes or regrinds through stationary and rotating blades. Wet granulators, in particular, introduce a continuous water stream during this process, offering both size reduction and initial cleaning of the plastic films, which can ultimately improve the washing process.

High-Speed Friction Washers

Serving as an essential component of a washing line, high-speed friction washers enhance cleaning efficacy. These machines utilize a rotating shaft equipped with angled panels surrounded by a mesh screen. As contaminated films pass through, friction created helps scrub off debris that is subsequently expelled, ensuring a cleaner output.

Gravity Separation Tank

The gravity separation tank aids in cleaning and separating contaminants, operating on the principle of density. Contaminants sink, allowing the plastic films to float and progress through the washing line. Its utility is especially notable for plastics like LDPE, simplifying the recycling process.

Drying Systems

Drying is the final step before extrusion into granules, as excess moisture can lead to defects in the finished product. Dewatering machines and thermal dryers are commonly used to ensure moisture content falls below recommended levels, facilitating quality output.
