In today' s thriving plastic recycling economy, efficiency, quality, and cost control are important for recycling businesses. Depending on years of market experience, Kitech Machinery presents the KSS series shredder & pelletizing machine – a highly integrated, intelligent, and efficient complete production line. This all-in-one system combines crushing and pelletizing, specifically designed to handle complex plastic wastes such as plastic scraps, regular film, PP raffia bags, hollow products, and foam materials. It is the ideal solution for reducing costs, boosting efficiency, and enhancing your product competitiveness.
Field tests were conducted on four common complex plastic wastes, with excellent results as shown in the following images:
1. LDPE Film
2. LLDPE Film
3. PP Raffia Bags
4. TPU Material
I. Integrated Design: Transforming Traditional Production
Traditional plastic recycling often requires multiple separate machines, leading to large footprints, high energy consumption, poor connectivity, and high labor dependency. The KSS Series innovatively integrates key processes-including shredding, crushing, feeding, plasticizing, degassing, filtering, cutting, and drying-into one compact line. This integrated design enables continuous, closed-loop processing, significantly reducing material loss and pollution from transfers.
II. The superior performance is from each core component:
1. Automatic Feeding & Pre-Crushing System:
A rubber conveyor belt equipped with a metal detector automatically feeds material at a stable, adjustable speed via a frequency converter. The specially designed crusher pre-processes large or irregular waste into uniform plastic flakes, ideal for the extruder, preventing blockages from the source.
2.Plasticizing & Vacuum Degassing System:
Featuring an optimized screw design for excellent plasticizing and higher output. A core highlight is the double vacuum degassing system, ensuring continuous operation. It effectively removes low-molecular substances, moisture, and printing inks from the melt, greatly enhancing the purity, color, and mechanical properties of the recycled pellets.
3. Durable Self-Cleaning Filtration System
(1) Extended Service Life: The disc mesh is made of high-strength chrome-molybdenum steel. Its robust 1.5mm thickness ensures long operational life, significantly reducing the frequency and cost of filter replacements.
(2) Lower Labor Costs: Say goodbye to frequent manual screen changes! The system is equipped with six high-efficiency scrapers that form a continuous cleaning mechanism, rapidly removing impurities from the filter surface. This allows for automatic cleaning even during the continuous production operations, minimizing unplanned downtime caused by manual screen changing and greatly boosting overall production efficiency.
(3) Superior Filtration Precision: Thanks to advanced laser technology, the filter is precision-drilled with thousands of micro-holes for efficient impurity removal. Filtration precision is adjustable within a range of 80 to 800 microns, ensuring optimal results for various material requirements.
4.Stable Underwater Pelletizing System:
Underwater pelletizing is an innovative and friendly plastic pelletizing technology. The core principle involves cutting the extruded polymer immediately while it is in a molten state. The pellets then enter a sealed water chamber, where the temperature difference of the cooling water causes these droplet-like pellets to solidify gradually, finally, forming near-spherical pellets.
This technology offers various advantages. It employs a sealed, circulating process, ensuring a clean and eco-friendly production environment. The resulting pellets exhibit a smooth and uniform surface, alongside high density, excellent flowability, and low adhesion characteristics, making them highly suitable for downstream processing and secondary production. Furthermore, the system has minimal space requirements, occupies a small footprint, and features low industrial water consumption, conform to energy-saving and environmentally conscious design principles.
5. One in Two Drying System:
Innovatively combines vibratory and horizontal centrifugal drying for high drying efficiency and low energy consumption. An integrated cooling water system with a heat exchanger allows for internal water recycling, embodying an eco-friendly design. Final pellet moisture content is below 3%.
6. Intelligent PLC Control System:
The entire line is controlled by a PLC system integrating premium components (Siemens/Schneider/ABB). The user-friendly HMI (Human-Machine Interface) supports one-touch start/stop, full-line parameter monitoring, and intelligent adjustment, simplifying operation, reducing the learning curve, and enabling stable, safe, and efficient production.
7. Automated Storage System:
As the final key stage, this system ensures pellets are stored under ideal, dry conditions, maintaining their quality for long-term storage, resale, or secondary processing.
III. All-in-One Solution: From Flakes to Pellets
The Kitech Machinery KSS series shredder & pelletizing machine resolves production bottlenecks through integration, enhances management efficiency via intelligent control, and guarantees product quality with key technological innovations. It represents the direction of development in plastic recycling: integrated, automated, and high-end. Choosing the KSS pelletizer means not just selecting equipment, but choosing a reliable partner for your sustainable business growth.
