I. Plastic Waste Sorting Steps and Core Equipment
1. Pre-treatment and Crushing Stage
Heavy-duty shredder, crusher
Mixed plastic waste first undergoes pre-treatment to remove large foreign objects, then is processed by powerful shredding equipment to homogenize the material size. Our high-speed shear crusher uses wear-resistant alloy blades and an intelligent speed control system, capable of processing various plastic packaging, bottles, cans, and films, with a capacity of 5-10 tons/hour, and energy consumption is reduced by 30% compared to traditional equipment.
2. Precision Sorting Stage
– Near-Infrared (NIR) Sorter: The core identification device, using spectral analysis to identify different plastics such as PET, HDPE, PP, and PS within milliseconds. The air jet system ensures precise separation, achieving a purity of up to 98%.
– Electrostatic Sorter: Specially designed for handling mixed fragments, using differences in conductivity to separate impurities such as PVC.
– Color Sorter: Equipped with a high-resolution CCD sensor, it performs secondary sorting by color, enhancing the value of recycled materials.
– Air Classification and Sedimentation System: Separates lightweight impurities such as films and labels.
3. Deep Cleaning and Granulation
Core Equipment: Friction Washer, Rinse Tank, Hot Air Drying System, Granulator
The sorted plastic fragments undergo multi-stage cleaning to remove contaminants before entering the granulation stage.
II. Alleviating Your Concerns
1. High cost and low efficiency of manual sorting
2. Insufficient purity in sorting, resulting in a low value of recycled materials
3. Poor equipment adaptability, unable to handle complex materials
4. Lack of transparent operational data, making optimization difficult
III. Economic Benefits and Environmental Value
Investing in a professional plastic sorting production line can recoup your investment within 2-3 years: processing 50 tons of mixed plastics daily can produce approximately 35 tons of high-purity plastic fragments. Based on current market prices for recycled plastics, the annual output value can reach tens of millions of yuan. Simultaneously, it reduces the use of virgin plastics, saving 1.5 tons of petroleum consumption and reducing carbon dioxide emissions by 3 tons per ton of recycled plastic.
Choosing professional and reliable intelligent sorting equipment not only improves the economic benefits of recycling but also actively participates in building a circular economy for plastics. As an equipment manufacturer, we provide not just machines, but complete solutions from process design, installation, and commissioning to operational optimization, helping users gain a competitive edge in this transformative wave.
