Last week, the Korean customer conducted an inspection and acceptance of the KSP series single-screw pelletizing machine, This pelletizing line is used for processing High-Density Polyethylene (HDPE) scrap materials with extremely low melt index values. The live trial highlighted the system's ability to transform post-industrial plastic waste into high-quality reusable pellets through an integrated recycling process. At the test site, our technicians had an in-depth discussion with customers on various professional parameters of the machine.
System Overview
Designed specifically for hard plastic recycling applications, the KSP series combines feeding, plasticizing, filtration, cutting and drying operations into a closed-loop system suitable for processing multiple material types including PP, PE, HDPE, ABS, PS, HIPS, and PC regrind flakes. Kitech Machinery KSP series pelletizing production line with high output can produce granules that meet production standards and can be reused.
Main parts of KSP series pelletizing production line
1.Stainless Steel Screw Feeder
Its main function is to transport the crushed raw materials into the single screw extruder. Kitech Machinery can customize different capacities according to the production needs of customers. It is equipped with a magnetic frame inside, which can effectively remove the magnetic metal to extend the service life of the main extruder.
2.High-Efficiency Single-Screw Extruder
Kitech's proprietary screw design delivers 20% greater output and plasticization ability than conventional extruders. Screw and barrel adopts wear-resistant alloy construction that extends service life by 150%.
3.Dual-Stage Degassing System
Dual vacuum ports actively remove moisture, volatile compounds, and residual inks to below 0.1% moisture content in final pellets.
4. Special heating and cooling system
Equipped with a specially designed cooling system, it can precisely control the melting temperature, keeping the heating temperature steadily within the range of 180 - 190 degrees Celsius. Under this temperature range, the material can achieve low - temperature melting and granulation, effectively avoiding the destruction of the material's properties and physical attributes caused by high temperatures.
5. Piston type filter (screen changer)
Effectively captures fine particles and contaminants due to the large filtration surface area.
Suitable for high-flow applications, reducing the need for frequent replacements. improved productivity.
Built-in static mixer improving product stability.
Superior sealing system completely eliminating polymer leakage.
6. Water Ring Pelletizer with Adaptive Cutting
The European-engineered cutting system employs frequency-controlled motors to maintain ±0.5mm pellet dimensional consistency, with anti-sticking water circulation ensuring smooth material flow.
7. Multi-Stage Drying System
Kitech Machinery drying system combines vibration and centrifugal drying modules achieve ≤0.05% residual moisture levels, meeting requirements for direct reuse in injection molding and extrusion processes.
8.Intelligent Control System
Kitech Machinery uses original Siemens PLC program and touch screen for one-touch startup with interlock safety protocols. Formula memory for multi-material processing no need to repeated setting parameters when changing raw materials.
9. Monitorable packaging system
This packing system equipped with double hopper storage system can increase the storage capacity by 150%. The pelletizing production line output can be monitored in real time and tracked.
10. Industrial Chiller
This pelletizing production line equipped with industrial water chiller, it has low noise, small footprint, stable performance and can effectively cool production water.
Performance Validation
During the HDPE recycling demonstration, the system achieved continuous throughput of 400-500 kg/h for materials with poor fluidity with energy consumption rates 15-18% below industry benchmarks. The resulting pellets exhibited uniform melt flow index (MFI) values and chromatic consistency, qualifying for Grade-A reprocessing applications.
