The color of the pellets is pure and consistent, without uneven coloring caused by ink residue or impurity mixing, which fully meets the quality standards of the local Namibian market for recycled plastic raw materials.
-
Glossy, Smooth Pellet Surface, Free of Bubbles and Imperfections: Thanks to the advanced degassing and filtration system of the plastic film pelletizing machine, the surface of the produced pellets is glossy and smooth, without any bubbles, burrs, or other defects. These high-quality pellets are highly sought after by downstream plastic product manufacturers in Namibia, laying a solid foundation for the client to expand its market share.
-
Optimized for PE Film Recycling, Strong Adaptability and Lower Energy Consumption: Specifically designed for PE film recycling, this plastic film pelletizing machine has strong adaptability to various waste PE films, including ordinary PE film, agricultural PE film, and packaging PE film. Compared with the client’s previous old equipment, the energy consumption of this plastic film pelletizing machine is reduced by about 25%, significantly lowering the client’s production costs and improving overall profitability.
Core System Configuration of KCP140+150 Plastic Film Pelletizing Machine
To ensure the stable and efficient operation of the plastic film pelletizing machine, Kitech has equipped the KCP140+150 model with a series of high-precision, high-performance core systems, each of which plays a crucial role in the entire PE film recycling pelletizing process. Below is a detailed introduction to each key system:
Feeding & Cutting Compacting System: The Foundation of Efficient Operation
As the first link of the plastic film pelletizing machine, the feeding and cutting compacting system is responsible for the initial processing of waste PE film. Waste plastic film is fed evenly and steadily into the cutting compactor system of the plastic film pelletizing machine via a high-quality rubber belt conveyor with adjustable speed. This system not only realizes uniform feeding but also integrates pre-heating, mixing, semi-plasticization, and pre-drying functions, effectively removing moisture from the raw materials and improving the plasticity of the plastic film.
In addition, Kitech’s independently developed intelligent temperature control system is applied to this part of the plastic film pelletizing machine, which can accurately control the pre-heating temperature of the raw materials, effectively preventing the overheating and degradation of PE film raw materials during the pre-processing stage. This not only protects the physical properties of the plastic raw materials but also lays a solid foundation for the subsequent plasticization and pelletizing process in the extruder.
Two-Stage Extrusion System: The Core of Quality Pellet Production
The two-stage extrusion system is the core component of the KCP140+150 plastic film pelletizing machine, consisting of two sets of single-screw extruders independently designed and developed by Kitech Machinery. These two extruders are reasonably matched in terms of screw structure, rotation speed, and temperature control, making the plastic film pelletizing machine especially suitable for processing difficult-to-handle raw materials such as heavily printed PE film, high-moisture-content PE film, and temperature-sensitive plastic film.
During the operation of the plastic film pelletizing machine, the pre-processed PE film raw materials enter the first-stage extruder for preliminary plasticization and degassing, and then enter the second-stage extruder for further plasticization, filtration, and secondary degassing. Through this two-stage extrusion process, the raw materials are fully plasticized, and impurities such as ink residue, sand, and metal particles in the plastic film are completely filtered out, ultimately producing high-purity, high-quality recycled plastic pellets that meet the client’s strict requirements.
PLC Control System: Intelligent Operation for Easy Management
To improve the operation convenience and safety of the plastic film pelletizing machine, Kitech has adopted a high-end PLC control system, equipped with renowned electrical components from international top brands such as Siemens, Schneider, ABB, and LS. This ensures the stability and reliability of the plastic film pelletizing machine’s control system, reducing the probability of electrical failures during long-term operation.
The user-friendly operation interface of the plastic film pelletizing machine supports one-touch start/stop, recipe memory, and safety interlock functions. The 3D visual touchscreen panel displays the real-time operation status of each part of the plastic film pelletizing machine, including temperature, rotation speed, output, and fault information, in an intuitive and easy-to-understand manner. This simplifies the operation tasks of the client’s operators, effectively reducing the learning curve, and enabling even inexperienced operators to master the operation skills of the plastic film pelletizing machine quickly.
Melt Filter & Water Ring Pelletizing System: Guaranteeing Pellet Uniformity
The melt filter system of the plastic film pelletizing machine adopts a plate-type automatic filter changer with a large filtration area, which is specially designed for high-volume, continuous production of the plastic film pelletizing machine. Its unique two-position design allows for screen changes without stopping the machine, minimizing downtime and ensuring the continuous and stable operation of the plastic film pelletizing machine.
Paired with a European-style water ring pelletizer, this part of the plastic film pelletizing machine can automatically adjust the cutting speed according to the melt pressure of the extruder, ensuring that the size of the produced plastic pellets is consistent and uniform. The water ring cooling system also plays a role in cooling and shaping the pellets, making the surface of the pellets smoother and improving the overall quality of the finished products.
Vibration Drying & Storage Silo System: Protecting Pellet Quality in the Final Stage
After being cut by the water ring pelletizer, the plastic pellets still contain a small amount of moisture, which will affect the storage and subsequent processing of the pellets if not handled in time. The vibration drying system of the plastic film pelletizing machine solves this problem effectively, which can evenly dry the plastic pellets and effectively prevent pellet agglomeration, ensuring that the moisture content of the finished pellets is kept below 3%—a key indicator for high-quality recycled plastic pellets.
As the final critical stage of the plastic film pelletizing machine production line, the storage silo system is designed with a sealed structure and a temperature and humidity control function, which can guarantee that the plastic pellets are stored under ideal conditions. This effectively prevents the pellets from being polluted by dust and moisture in the air, preserving their quality for subsequent processing and sales, and further enhancing the client’s product competitiveness in the Namibian market.
