What is the workflow of the plastic recycling cleaning line?
First, the recycled plastic is sent to the pre-shredding process. This link uses professional crusher equipment, which can quickly break large pieces of plastic into small pieces, which is convenient for subsequent treatment. This step not only reduces the material volume, but also improves the processing efficiency.
Next comes the friction cleaning. After the pre-shredded plastic pieces into the cleaning equipment, through friction and cleaning to remove surface dirt and impurities. This step is crucial to ensure that recycled plastics are up to standard for reuse.
The cleaned plastic then enters the extrusion process. In this step, the plastic through centrifugal dehydration, spiral extrusion drying and other processes to remove excess water, so that the plastic moisture content is strictly controlled within a certain range, providing favorable conditions for subsequent processing.
This is followed by the crushing process. The squeezed plastic enters the crusher, where it is broken into particles of uniform size. These granular plastics are not only easy to store and transport, but also provide convenience for subsequent processing and utilization.
The final step is the granulation process. The crushed plastic particles are further compressed into plastic particles with a certain shape and specification through the extrusion system of the granulator. These plastic particles can be directly used to produce new plastic products, thus realizing the reuse of resources.
In addition to the main steps mentioned above, the plastic recycling cleaning line also includes some auxiliary equipment and processes, such as metal detectors for detecting and removing metal impurities from plastics, and de-labeling systems for removing labels that may remain. The application of these equipment and processes further improves the purity and utilization rate of plastic recycling.
