In the process of plastics recycling, waste plastics are often attached to various impurities, such as oil, sludge, colored substances, etc. These impurities will affect the subsequent processing and reuse.
Friction washing machines efficiently remove these contaminants attached to the surface of plastics through mechanical friction and hydraulic rinsing, improving the quality and reusability of recycled plastics.
This type of equipment is typically used in the sorting and preparation stage of plastic waste to provide clean plastic raw materials for subsequent production processes.
plastic friction washer application range
The main applications of the friction washing machine include: cleaning all kinds of waste plastics, such as bottle chips, films, hard plastics, etc., and removing oil and pigments on the surface.
It also removes residual liquids, labels, and other contaminants on the surface of bottles, improving the recycling quality of plastics.
frictional washing machine structure detail
Friction washers have the advantage of having unique blades and spirals that include rotating brushes, spray systems and rinse tanks that are clearly cleaner. The housing and structural materials are usually made of corrosion and abrasion-resistant materials to ensure stability and durability over a long period of time.
Cleaning process of a high-speed friction washer
- 进料输送机： The waste plastics are conveyed to the feed opening of the friction washer, which is usually carried out with an elevating conveyor.
- Friction Cleaning: The friction washing machine is usually equipped with friction wheels or brushes, by rotating or vibrating, the waste plastics undergo strong mechanical friction, effectively removing the adhering impurities.
- Water Rinsing: During the cleaning process, water is sprayed or injected to rinse away impurities and other contaminants dislodged during the friction process.
- Separation Processing: The cleaned plastic is separated from the water and impurities, usually by means of screens or other physical separation.
- Discharge and Reuse: The cleaned plastic pellets are discharged, and ready for the next step in the production process. The water used in the cleaning process can be treated so that it can be used again for water recycling.
friction washing machine advantages
Friction washers offer several advantages in plastic recycling lines, including:
- Efficient decontamination: Use mechanical friction to efficiently remove adhering contaminants from the surface of plastics, including grease, asphalt, and pigments.
- Widely Applicable: Suitable for different kinds of waste plastics, including bottle flakes, films, hard plastics, etc.
- Automatic operation: Realize automatic cleaning process and improve production efficiency.
- Water Recycling: Some friction washing machines are designed with a water recycling system, which reduces the waste of water by recycling the cleaning water.
Prospects for friction washers
Shuliy’s friction washers have been successfully exported to many countries around the world, including but not limited to the United States, Canada, the United Kingdom, Germany, France, Australia, Brazil, India, Japan, South Korea, South Africa, and so on.
Friction washing machines have a promising future in plastic recycling lines with the improvement of environmental protection awareness. The cleaned high-quality recycled plastics can be widely used in various fields, including packaging, construction, automotive, etc., providing sustainable plastic materials for different industries.
