Turkmenistan-KCP Pelletizing System for PP Yarn Recycling Plant
Against the trend of green industrial upgrading and the booming plastic circular economy in Turkmenistan, the local waste plastic recycling sector is shifting away from extensive processing mode toward refined, standardized and high-quality production. Waste PP yarn, a major raw material from local textile and packaging industries, possesses great recycling value. Nevertheless, restricted by defects of outdated processing equipment, enterprises have long encountered low recycling efficiency, contaminated pellets and unstable product quality.
To tackle the bottlenecks in PP yarn pelletizing, a professional plastic recycler in Turkmenistan made comparisons among global equipment suppliers and finally cooperated with KITECH Machinery. The customer purchased the customized KCP series strand pelletizing system, a reliable polypropylene recycling machine and core unit of the whole pp yarn recycling plant. This set of plastic recycling pelletizing machine has been operating continuously and steadily for 2 years, consistently supplying customers with high-purity standardized recycled PP pellets. It has become a benchmark project of refined polypropylene yarn recycling in Turkmenistan.
Customer’s Core Pain Points
The Turkmenistan customer has rich experience in local waste plastic recycling business, with stable supply channels of waste PP yarn and mature sales market for recycled pellets. The customer already owns a complete PP yarn washing line to finish impurity separation, washing and drying of raw materials. However, as local recycled plastic standards keep rising and downstream buyers raise higher requirements on pellet purity, color appearance and physical stability, the old pelletizing production line gradually exposed obvious drawbacks, restricting capacity expansion and profit growth. The main deficiencies of the original line are listed below:
Poor compaction and plasticizing effect leading to low pellet purity: The traditional pelletizing equipment lacks professional agglomeration and compaction structure. Even after washing, fluffy PP yarn cannot be fully densified. Massive air remains inside materials, resulting in cavities and bubbles inside finished pellets. In addition, fine residual impurities cannot be effectively filtered, so the recycled pellets fail to meet the standards of mid-to-high-end markets, limiting product profit margin.
Poor adaptability to PP yarn and unstable production: Waste PP yarn is lightweight, fluffy and easy to tangle. The old line is not equipped with special fixed-length cutting equipment. Yarns of uneven length frequently wind, agglomerate, bridge and block the feeding section, requiring frequent shutdown for cleaning. Meanwhile, outdated temperature control causes uneven melting of PP yarn and fluctuating melt flow rate. Frequent strand breakage, irregular particle size and rough surface become common defects during production.
No color modification function with single product categories and low added value: The conventional pelletizing line only supports basic melting and pelletizing without color matching devices. Produced recycled pellets have messy colors and obvious color difference. The customer cannot customize PP pellets with unified colors according to order demands and can only sell low-priced natural-color materials, which greatly restricts application scenarios and profitability.
Low equipment compatibility and high operation & maintenance costs: The old pelletizing machine is single-purpose equipment only suitable for regular PP yarn processing, unable to process flexible plastics such as films and woven bags, leading to low equipment utilization. In addition, high aging failure rate, high energy consumption and heavy manual dependence push up long-term maintenance costs, failing to satisfy the enterprise’s demands for large-scale and diversified low-cost production.
Customized Solution from KITECH Machinery
Targeting the customer’s existing independent PP yarn washing line and demand for backend pelletizing upgrading, combined with production conditions, site layout and capacity requirements in Turkmenistan, KITECH Machinery developed the tailored KCP series strand pelletizing system. As a high-performance polypropylene recycling machine, it forms the key part of a complete pp yarn recycling plant. This advanced plastic recycling pelletizing machine perfectly connects the customer’s front-end washing line, focusing on post-washing yarn deep processing including cutting, agglomeration, melting, color modification, filtration and water-cooling pelletizing.
The complete set consists of core equipment: one plastic yarn cutter, one belt conveyor, integrated agglomerator & single-screw extruder, color masterbatch dosing machine, screen changer and water-cooled strand pelletizing system. All modules operate coordinately to realize standardized and high-efficiency production from clean PP yarn to high-quality recycled pellets.
Standardized Production Process
The KCP series strand pelletizing system, as core equipment of the pp yarn recycling plant, is optimized for clean PP yarn characteristics. This mature plastic recycling pelletizing machine and professional polypropylene recycling machine effectively solve difficulties including insufficient compaction, uneven plasticization and uncontrollable color existing in traditional old lines. The detailed processing flow is as follows:
Fixed-length cutting: Clean and dried PP yarn transported from the customer’s self-owned washing line enters the plastic yarn cutter, and is cut evenly into 3–5 cm fragments. This step eliminates tangling and uneven feeding of fluffy yarn, unifies material form and lays a solid foundation for subsequent compaction and melting.
Automatic conveying and agglomeration compaction: Cut PP yarn fragments are delivered stably via belt conveyor into the agglomerator. Through high-speed shearing, rubbing and compaction, light and fluffy yarn pieces are further shredded and densified. Material bulk density is greatly improved; air cavities inside raw materials are removed. Problems such as material bridging and blockage are avoided to ensure continuous feeding and overcome insufficient compaction of traditional equipment.
High-temperature melting and plasticization: Compacted PP materials are sent into the single-screw extruder. Precise temperature control enables uniform heating and thorough melting into homogeneous liquid plastic. Full plasticization stabilizes melt flow performance, eliminating uneven melting and unstable discharging issues from old equipment and guaranteeing fundamental pellet quality.
Intelligent color modification: Equipped with an independent color masterbatch dosing machine, this polypropylene recycling machine can proportion various color masterbatches accurately according to order requirements. Color masterbatches are mixed evenly with molten plastic to control the tone and gloss of final pellets. Uniform appearance enables customized differentiated products and improves market competitiveness.
Precision filtration and purification: Molten plastic with color masterbatch passes through the plate screen changer for multi-stage fine filtration. Tiny residual impurities, dust and carbonized particles are intercepted completely. The purity of plastic melt is further enhanced, preventing black spots and defective particles to make up the weakness of low filtration precision on conventional equipment.
Water-cooling forming and pellet discharging: Purified high-quality molten plastic flows into the water-cooled strand pelletizing system. Plastic strands are shaped after rapid water cooling, then processed through automatic dewatering and cutting. Finally, uniform, consistent and high-purity recycled PP pellets are obtained, which can be directly applied in downstream plastic manufacturing.
