I. Complete Equipment Configuration Details of The HDPE Recycling Plant Project
This Saudi Arabia project adopts a customized, integrated HDPE pipe recycling and pelletizing production line, a tailor-made plastic pipes recycling solution independently developed by Kitech Machinery. The front-end of the production line is equipped with a professional large-diameter HDPE pipe shredding, crushing and washing system, while the back-end is matched with a high-efficiency KSP series single-screw pelletizing system, forming a complete set of core plastic pipes recycling machine combinations. The entire HDPE recycling plant features scientific configuration, compact and integrated technological processes, and a high degree of intelligent automation.
The full equipment configuration of this plastic pipes recycling solution includes: 1 set of AGR series hydraulic pusher + automatic pipe-turning feed shredder, 1 set of AGF series special plastic pipe crusher, supporting screw conveyor, low-speed friction washing unit, professional circulating rinsing tank, centrifugal dewatering machine, KSE series single-screw extruder, high-precision plate filter, and complete water-ring pelletizing system. This professional plastic pipes recycling machine is specially designed for the recycling and reprocessing difficulties of large-diameter HDPE pipes, and supports the processing of multiple types of plastic materials, with strong versatility and practicality, making it a cost-effective HDPE recycling plant for Middle Eastern waste plastic recycling projects.
II. Core Process Flow: Fully Automated Closed-Loop Recycling & Pelletizing Production
The whole set of plastic pipes recycling production line is equipped with a PLC intelligent centralized control system, realizing fully automated unmanned operation and precise, efficient process docking. This intelligent configuration greatly reduces manual intervention, avoids human operation errors, and ensures long-term stable and consistent quality of recycled plastic pellets. To fully display the operational advantages of Kitech’s professional plastic pipes recycling solution, we divide the core process into two core modules: HDPE large-diameter pipe shredding & washing line and single-screw pelletizing line, with detailed process explanations as follows:
1. HDPE Large-Diameter Pipe Shredding, Crushing & Washing Pretreatment Process
After waste HDPE pipes are recycled and fed into the plastic pipes recycling production line, they will complete a complete set of pretreatment procedures including shredding, fine crushing, deep impurity washing, centrifugal dehydration and drying, providing clean and high-purity raw materials for subsequent pelletizing production, which is the key link of the entire plastic pipes recycling solution.
Waste large-diameter HDPE pipes are neatly placed at the automatic pipe-turning feeding station. After the PLC intelligent system issues production instructions, the automatic pipe-turning device completes precise feeding, and cooperates with the supporting hydraulic pusher to stably and uniformly send large-size and long-specification HDPE pipes into the AGR series shredder. The exclusive hydraulic feeding structure effectively solves the jamming and clogging problems in the feeding process of large plastic pipes, greatly improving the operational stability and safety of the HDPE recycling plant during heavy-load production.
After strong shear shredding by the professional shredder, HDPE pipes are crushed into uniform 3×3cm medium-sized plastic fragments, completing the initial volume reduction treatment. The fragments are stably conveyed to the AGF series special crusher through a dedicated conveyor belt for secondary fine crushing, grinding the materials into uniform small particle fragments, completely dispersing pipe edge residues and hard plastic lumps, and laying a solid foundation for subsequent deep cleaning and pelletizing.
The finely crushed HDPE materials sequentially enter the low-speed friction washing unit and professional circulating rinsing tank. Through the dual purification process of low-speed flexible friction scrubbing and circulating water rinsing, surface attachments such as sediment, oil stains, dust, aging coatings and various residual impurities on waste pipes are completely removed, thoroughly solving the industry pain points of incomplete cleaning and high impurity residue in traditional plastic pipe recycling. After deep purification, the wet materials are sent to the high-speed centrifugal dewatering machine for rapid dehydration and drying, removing surface residual moisture, and finally obtaining clean, dry and impurity-free HDPE refined fragments that fully meet the raw material standards for pelletizing production of the HDPE recycling plant.
As the core pretreatment link of the plastic pipes recycling solution, fine crushing and deep cleaning determine the purity of final recycled pellets. After initial shredding, HDPE pipe fragments are uniformly conveyed to the AGF series fine crusher for secondary refining and crushing, ensuring consistent material particle size and eliminating large residual impurities. The refined materials then enter the multi-stage washing system for deep purification, completely stripping stubborn impurities on the surface of waste HDPE pipes.
After full cleaning and purification, the high-efficiency centrifugal dewatering equipment quickly removes material moisture, avoids the impact of moisture on subsequent pelletizing molding and product quality, and provides high-quality dry raw materials for the stable operation of the subsequent plastic pipes recycling machine.
2.KSP Series Single-Screw Pelletizing System Process Flow：
The clean and dry HDPE refined fragments processed by the pretreatment washing line are quantitatively and stably conveyed to the downstream pelletizing system, completing the whole process of melting plasticization, precision filtration, water-ring pelletizing, circulating water cooling and centrifugal spin-drying, and finally producing high-quality recycled HDPE pellets. This advanced pelletizing process is the core finishing technology of Kitech’s plastic pipes recycling solution.
Qualified HDPE fragments are uniformly fed into the KSE series single-screw extruder through a quantitative screw feeder. The equipment is equipped with a high-precision constant temperature control system, which matches exclusive melting and plasticizing parameters according to the physical characteristics of HDPE materials, fully melting and homogenizing solid plastic fragments into uniform and stable plastic melt. The molten plastic enters the high-precision plate filter for deep multi-layer filtration, thoroughly removing trace impurities, black spots and carbonized particles in the melt, significantly improving the purity and uniformity of the plastic melt, and ensuring the excellent appearance and stable performance of recycled pellets from the source.
The purified high-purity plastic melt is sent to the professional water-ring pelletizing system. Through high-speed rotary pelletizing, circulating water rapid cooling molding and high-speed centrifugal drying, the system efficiently completes pellet forming, cooling and dehydration, producing round, uniform, clean, low-moisture and high-stability HDPE recycled pellets. The finished recycled pellets can be directly used for secondary processing of various plastic products, with extremely high market application value, making this HDPE recycling plant highly profitable for end users.
This customized plastic pipes recycling machine is not limited to HDPE pipe recycling processing, with ultra-strong material compatibility and scenario adaptability, becoming a universal plastic pipes recycling solution for multiple waste plastic materials. In addition to various specifications of HDPE rigid pipes and other plastic pipes, the HDPE recycling plant can efficiently process PP, PE, ABS, PS, HIPS, PC and other mixed rigid plastics, covering waste plastic crates, plastic buckets, industrial rigid plastic scraps and various recycled raw materials.
The multi-functional design of the equipment helps customers enrich recycled product categories, flexibly adapt to the diverse material sources of the local Middle Eastern waste plastic recycling market, effectively reduce equipment procurement costs and factory site investment, and maximize the utilization rate and economic benefits of the plastic pipes recycling machine.
