Countries around the world have successively issued stricter waste plastic recycling regulations, and plastic recycling factories have invested a lot in integrated production units composed of Plastic Crusher and PVC hot-melt granulation lines, promoting the rapid development of the global circular plastic economy. Industry statistical data shows that the proportion of recycled plastic raw materials used in plastic processing increased by 9.2% year-on-year, driving the continuous technological iteration and market expansion of crushing and granulation equipment.
The high-efficiency plastic crusher is equipped with wear-resistant alloy rotary blades, which can shear waste plastic pipes, profile leftover materials, defective injection molded parts and discarded plastic sheets into uniform fragments. The screen mesh with adjustable aperture can control the particle size of crushed materials to meet the feeding standard of downstream granulation lines. The crushed plastic fragments are transported to the PVC hot-melt granulation production line through a fully sealed spiral feeder, and converted into standardized uniform recycled pellets after mixing melting, hot surface cutting and air-water dual cooling.
A complete closed-loop resource circulation system is formed in the whole workshop: waste plastic crushing → automatic sealed feeding → melt granulation → pellet cooling screening → finished recycled pellet storage → re-transport to plastic extrusion line to manufacture new pipes and profiles. The new granulation line can mix up to 35% waste PVC materials without reducing the mechanical performance of finished products, which has been verified by third-party material testing institutions. Segmented electromagnetic heating and waste heat recovery systems reduce the power consumption of granulation units by 23% compared with old generation recycling equipment.
Many regional governments have launched special recycling subsidies to reduce the procurement threshold of compact integrated crushing and granulation units for small recycling enterprises. Equipment manufacturers optimize the noise reduction structure of the plastic crusher to meet the factory noise limit standard of urban recycling plants. With the continuous tightening of single-use plastic waste management policies worldwide, the market scale of plastic recycling processing machinery represented by crushers and granulation lines is expected to grow at an annual compound rate of 7.1% until 2032, becoming a high-potential subdivision track in plastic machinery manufacturing.
