The making of recycled plastic pellets is of great significance to the environment and saving resources. The following is the process of making plastic pellets.
The process of making recycled plastic pellets includes recycling and sorting, crushing, washing, drying, and pelletizing. Attention to detail is required in each step to ensure that the quality of the recycled plastic granules produced meets the requirements.
Recycling and sorting
The production of recycled plastic pellets first requires recycling and sorting from waste plastics. Recycled waste plastics include waste plastics from various manufacturers, factories, and households. The plastics are categorized according to their type and characteristics to facilitate subsequent processing.
Crushing
Recycled waste plastics need to be crushed to convert large pieces of waste plastics into small pieces. Crushing can be achieved by using plastic crusher equipment, which turns waste plastics into small particles after multiple processes.
Washing
There are some impurities in the crushed waste plastics, which need to be cleaned and processed. In the process of cleaning, physical or chemical methods can be used to remove residual stains, oil, chemical residues, and so on.
Drying
Plastics need to be kept in a dry state during the production process, otherwise, they can easily be affected by moisture in the humid air, leading to an increase in the scrap rate. Therefore, the waste plastics after cleaning need to be dried.
Making recycled plastic pellets
Extrusion is one of the more common ways to make recycled plastic pellets. The production process includes the steps of melting, extruding, and cooling. The dried plastic is added to the recycled plastic pelletizer for melting and heating. The melted plastic is then extruded through a die to form certain shapes of recycled plastic pellets.
