All in One Solution: Kitech KSS Series Shredder and Pelletizing Machine

In today's booming plastic circular economy, efficiency, quality, and cost control are core concerns for recycling companies. Based on years of market experience, Kitech Machinery has launched the KSS series shredder and pelletizing machine—a highly integrated, intelligent, and efficient complete production line. It integrates crushing and granulation, specifically designed for processing complex waste plastics such as plastic scraps, plastic films, raffia, hollow products, and foamed materials. It is your ideal choice for reducing costs, increasing efficiency, and enhancing product competitiveness.

On-site testing focused on four common complex plastic wastes. The results, as shown in the image below, are excellent:

1. LDPE film

2. LLDPE film

3. PP raffia bags

4. TPU material

I. Integrated design, revolutionizing traditional production models

Traditional plastic recycling often requires multiple machines operating in stages, resulting in pain points such as large footprint, high energy consumption, poor coordination, and strong reliance on manual labor. The KSS series innovatively integrates key processes such as shredding, crushing, feeding, plasticizing, degassing, filtering, pelletizing, and drying into a compact production line. This integrated design enables continuous, closed-loop material processing, significantly reducing losses and pollution caused by material transfer, and substantially saving space and energy.

II. Core Component Advantages Showcase Technological Strength

1. Automatic Feeding and Pre-crushing System:

A rubber conveyor belt equipped with a metal detector automatically transports materials, with the feeding speed adjusted by a frequency converter to achieve stable and uniform feeding. A specially designed crushing device pre-crushes and cuts large-sized, irregularly shaped waste materials, providing the extruder with uniformly sized, easily plasticized material, fundamentally solving the problem of material blockage.

2. Plasticizing and Vacuum Degassing System:

KSS's optimized screw design delivers excellent plasticizing effects and higher output. Its core highlight lies in its double-vacuum degassing system. The double-chamber design ensures continuous, uninterrupted operation, effectively removing low-molecular-weight substances, moisture, and printing ink from the melt, significantly improving the purity, color, and mechanical properties of the regenerated particles.

3. Durable Self-Cleaning Filtration System:

（1）Extended Service Life: The core component, the laser filter screen, is made of double-layer hard alloy. Its 1.5 mm thickness ensures an ultra-long service life, reducing the frequency and cost of filter screen replacement.

（2） Reduced Labor Costs: Say goodbye to frequent manual screen changes! The system is equipped with six high-efficiency scrapers, forming a continuous cleaning mechanism that quickly removes impurities from the filter screen surface. This ensures automatic cleaning even during continuous operation, reducing downtime caused by manual screen changes and significantly improving production efficiency.

（4） Superior Filtration Accuracy: Thanks to advanced laser technology, the filter screen is covered with thousands of precision drilled holes, enabling efficient impurity removal. Filtration accuracy is adjustable between 80 and 800 microns.

4. Stable Underwater Pelletizing System:

Underwater pelletizing, an innovative and environmentally friendly plastic pelletizing technology, employs advanced cutting technology to adjust pellet size and shape according to different needs, ensuring uniformity and consistency of the pellets. Its main principle is that blades immediately pelletize the polymer extruded in its molten state. In a closed water chamber, aided by the temperature difference of the cooling water, these droplets gradually solidify, eventually forming near-spherical pellets.

Underwater pelletizing technology offers numerous advantages. It utilizes a closed-loop circulation process, ensuring a clean and environmentally friendly production process. The pellets exhibit a smooth and uniform surface, along with high density, good flowability, and low adhesion, making them ideal for subsequent secondary processing. It has low site requirements, requires little floor space, and consumes little industrial water, resulting in energy conservation and environmental protection.

5. Efficient Two-in-One Drying System:

This innovative system combines vibration drying and horizontal centrifugal drying, achieving high dehydration efficiency and low energy consumption. The built-in heat exchanger and circulating water cooling system enable internal recycling of cooling water, embodying an environmentally friendly and energy-saving design concept. The final product pellets have a moisture content of less than 3%.

6. Intelligent PLC Control System:

The entire system integrates electronic components from major brands such as Siemens, Schneider Electric, and ABB. Equipped with an intuitive Human-Machine Interface (HMI), it supports one-button start/stop, full-line parameter monitoring, and intelligent adjustment. Intelligent control significantly reduces operational difficulty and worker learning costs, making stable, safe, and efficient production readily available.

7. Automated Storage System:

As the final critical step in granulation production, the storage system ensures your plastic granules are always stored under ideal, dry conditions. This ensures the plastic granules remain in good condition for extended periods and can be resold and processed.

Kitech Machinery's KSS series shredder and pelletizing machine solves production bottlenecks through integrated design, enhances management efficiency through intelligent control, and guarantees product quality through key technological innovations. It represents the direction of plastic recycling and processing towards integration, automation, and high-end development. Choosing a KSS crushing and granulating line is not just choosing a piece of equipment, but choosing a reliable partner to support your company's sustainable development.
