Scrap UPVC Window Profiles Shredder
Scrap UPVC Window Profiles Shredder for UPVC window and door recycling and sorting lines.
As the renovation of old buildings and the replacement of doors and windows continue, large quantities of waste UPVC window profiles are being discarded. These profiles are often contaminated with steel reinforcements, hardware, rubber gaskets, glass fragments, and silicone residues; manual dismantling and sorting are inefficient, costly, and yield low-purity recycled material. By utilizing specialized Scrap UPVC Window Profiles Shredders and automated Scrap UPVC Window Profiles crushing and sorting lines, waste UPVC windows and doors can undergo one-stop processing—including shredding, impurity removal, and sorting—to produce high-purity recycled UPVC. This supports the plastic recycling industry in enhancing quality and efficiency while promoting eco-friendly production.
The waste UPVC window profile shredder serves as the core primary shredding unit in the recycling line, specifically designed for whole window frames (including steel reinforcements) and long profiles. Mainstream models typically feature a dual-shaft design operating at high torque and low speed; wear-resistant alloy steel cutters prevent jamming and withstand heavy use, allowing for direct feeding without the need for manual dismantling. The output particle size is flexibly adjustable between 10mm and 50mm, ensuring uniform primary shredding while protecting downstream fine-shredding equipment from damage caused by hard objects like steel reinforcements. For profiles that have already been cut to uniform lengths, a single-shaft shredder may be used; utilizing a hydraulic pusher and screen-controlled discharge, it produces more uniform output, laying the groundwork for precise sorting.
Since a single dual-shaft waste shredder cannot effectively remove impurities such as metal, rubber gaskets, and glass, a complete UPVC window profile crushing and sorting line enables a fully automated, closed-loop recycling process. The streamlined, efficient workflow encompasses feeding, primary shredding, iron removal, fine shredding, non-metallic material sorting, air-based density separation, washing and dedusting, and dewatering/screening. First, magnetic separation equipment precisely removes ferrous metals—such as internal steel reinforcements and iron nails—from the profiles, preventing equipment damage caused by hard objects. Next, an eddy current separator removes non-ferrous metals like copper and aluminum (found in hinges and locks), enabling the separate recovery and value enhancement of these metal scraps.
To handle various impurities—ranging from light materials like rubber strips and dust to heavy contaminants like silicone and glass fragments—the Scrap UPVC Window Profiles crushing and sorting line integrates air-based density separation and water-washing systems. By leveraging the specific gravity differences between UPVC and contaminants, the system thoroughly separates soft debris and glass residue while removing surface dirt and adhesive traces. High-configuration lines can include optical sorting equipment to automatically distinguish between white, colored, and wood-grain laminated UPVC materials; this graded processing significantly boosts the market value of the recycled plastic. The entire system requires only one or two operators, offering a high degree of automation and minimal labor costs.
The Scrap UPVC Window Profiles crushing and sorting line offers flexible capacity, typically ranging from 500 kg/h to 3 t/h, to meet the mass-production needs of small- and medium-sized recycling facilities. The system operates in a fully enclosed environment and features a professional dust collection system that effectively captures PVC dust, ensuring compliance with environmental emission standards. Additionally, the equipment incorporates a smart temperature control design to prevent high-temperature decomposition of UPVC—which could release harmful substances—thereby ensuring operational safety.
The resulting recycled UPVC material boasts high purity and minimal impurities, making it suitable for direct extrusion and pelletizing. It can be used to manufacture new products such as plastic-steel doors and windows, PVC piping, and plastic fittings, thereby transforming waste construction materials into valuable resources. Compared to traditional manual dismantling and crude crushing methods, this integrated system delivers higher recovery rates and superior material purity; it not only resolves the pollution and waste issues associated with discarded plastic-steel windows and doors but also generates significant economic returns for enterprises, making it an optimal solution for construction plastic recycling.
