PS/ABS recovery cleaning lines, play a critical role in dealing with the ever-growing problem of plastic quantities. This article will explore the essential elements of plastic quantity handling and provide observations and best practices to help industry players optimize their PS/ABS recovery cleaning processes.
ABS/PS shell crushing and cleaning production line overview
With the rapid renewal of technological products, the amount of electrical and electronic equipment waste (WEEE) has surged, of which about 40-50% is composed of ABS/PS shell materials. To effectively recycle these waste shells, ABS/PS shell crushing ABS/PS shell purification production line’s essential task is to waste electrical shells in the ABS (acryl styrene-butadiene-styrene) and PS (polystyrene) plastic separation, crushing, and further cleaning, drying, and processing, and ultimately get high-purity ABS and PS raw material particles.
These pellets are reused in plastic enclosure processing plants to produce various plastic products to meet the rapidly growing demand for materials in the environmental market.
In addition to powder, the ABS/PS purification line is also significant to environmental protection—traditional landfill or skeleton disposal methods cause severe pollution to the ecological environment. At the same time, recycling technology across the production line reduces emissions and ensures the sustainable use of resources, creating a virtuous circular economy model.
Production line working principle
The ABS/PS shell crushing and cleaning production line mainly contains the following working stages:
Waste shell crushing:
- The collected waste ABS/PS shell crusher will be crushed to break the large shell into small pieces.
Brine Cleaning:
- When cleaning, the tank rotor being crushed will be cleaned with brine, and the difference in buoyancy of the tank brine will be utilized to separate materials of different materials from the tank.
Dehydrator:
- Put the cleaned materials into the dewatering machine, and through the centrifugal force, shock out the water in the materials and reduce their water content.
Hot air drying:
- The dewatered material is fed into the hot air dryer to further reduce the moisture content of the material through the hot air effect of the pipeline.
Aqueous and mechanical cleaning in PS/ABS recovery cleaning lines
PS/ABS recycling washing lines utilize different washing technologies to reduce plastic emissions and ensure the quality and deviation of the recycled material. The key technologies are aqueous and mechanical cleaning.
Aqueous Cleaning
- High-pressure water streams improve plastic surface concentration, reduction, and organic matter.
- Suitable for expanded plastic quotas such as bottles, cans, containers, and films.
- Advantages: High efficiency, low cost, removes most surfaces.
Mechanical Cleaning
- Utilizes friction and abrasive action to increase volume in plastics, such as plastic labels, stickers, and metals.
- Suitable for more minor plastic releases such as thinning, chips, and powders.
- Advantages: Can become increasingly unmanageable and improve the performance of recycled materials.
Appropriate cleaning technology should be used according to the release’s characteristics, size, and degree of contamination. Combining aqueous and mechanical cleaning effectively removes a wide range of contaminants and ensures that the selection of recycled materials meets market specifications and application requirements.

| Cleaning Technology | Description | Applicable to | Advantages |
| Aqueous Cleaning | Increased concentration, reduction, and organic matter on plastic surfaces using high-pressure water streams. | Expanded plastic emissions (bottles, cans, containers, film) | Efficient and cost-effective, it can reach most surfaces. |
| Mechanical Cleaning | Increases the volume of plastic (plastic labels, stickers, metals) using friction and abrasive action. | Reduced plastics emissions (slices, chips, powder) | It enhances recalcitrance and improves the performance of recycled materials. |
PS/ABS Recovery Flotation Sorting in Cleaning Lines
Flotation sorting is a method that utilizes the difference in density of different materials to separate the recyclables by penetrating a fluid medium. In the PS/ABS recycling washing line, flotation sorting is mainly used to separate the lower-density PS (polystyrene) and the higher-density ABS (acryl styrene-butadiene-styrene) plastics.
Principle of flotation sorting:
The principle of flotation sorting is equivalent to adding the recovered material to a tank containing a liquid medium. The density of the fluid medium is lower than that of PS and higher than that of ABS, but the PS particles are suspended in the fluid medium, and the ABS particles sink to the bottom.
Advantages of flotation sorting:
Flotation sorting is an efficient and accurate sorting method. It has the following advantages:
- High accuracy: it can effectively separate PS and ABS particles according to the density difference.
- High efficiency: continuous operation, large processing capacity, and ability to meet the demand for recyclables sorting in large quantities.
- Environmental protection: adopting liquid medium, using chemicals, and being environmentally friendly.
Application of flotation sorting:
Flotation sorting is widely evaluated in PS/ABS recycling cleaning lines. It can effectively separate PS and ABS particles and improve the quality and value of recycled plastics. Recycled plastics can be further used to manufacture various products, such as automobile parts, electronic product shells, and packaging materials, promoting resource recycling.
Manual sorting in PS/ABS recycling washing lines
Although automated equipment has dramatically improved recycling efficiency, manual sorting is critical in PS/ABS recycling washing lines. Visual inspection utilizing human labor can further remove losses that cannot be detected by the machine, ensuring that the recycled materials are The following describes the critical steps of manual sorting in PS/ABS recycling washing lines:
Visual Inspection:
- The operator will carefully inspect the cleaned PS/ABS pellets, picking out differences in color, shape, or size.
Manual Sorting:
- The selection type will be sorted into categories, such as paper, metal, or other plastics, for subsequent processing and recycling.
Quality control tubes:
- Manual sorting provides additional quality control tube measures to ensure the total amount of recycled material meets the required specifications and standards.
Customer Needs Specific:
- Manual sorting can be customized to meet specific differences or specifications for customers with special requirements.
By combining automated technology and manual sorting processes, PS/ABS recycling lines can effectively remove cleanup and produce high-quality recycled material. Manual sorting is the last line of defense to ensure optimal quality and grading standards the customer sets before introducing the recycled material into the manufacturing process.
Conclude
ABS/PS shell crushing and cleaning production lines play a vital role in promoting the sustainable development of the industry and the permanent utilization of resources, and they provide supportive backing for the practice of a circular economy.
The production line effectively recycles valuable raw materials and reduces the environmental burden by utilizing the crushing and cleaning process of waste ABS/PS shells. This reuse minimizes the dependence on original resources, enhancing the industry’s added value and creating new economic opportunities.
