Zhangjiagang, China – July 2025 – Kitech Machinery has successfully trialed its groundbreaking Automatic Laser Filtration System integrated with a Melt Pump, setting a new standard for efficiency in filtering complex contaminants from diverse recycled plastics. This innovative solution tackles a critical industry challenge: purifying impurities in waste plastic to produce high-quality pellets.
Designed specifically for demanding recycling applications, the system excels at filtering challenging impurities found in recycled PP, PE, LDPE, HDPE, PS, EPS, ABS, PVB, PVC, and more. It effectively removes a wide range of impurities, including:
Metals: Iron, steel, aluminum, copper
Organics: Wood chips, paper, textile fibers
Mineral/Other: Sand, stones
Unmelted plastic particles
This comprehensive filtration significantly improves the quality and consistency of the final recycled pellets.
I. Auto Laser Filter Advantage: Core Benefits
The heart of the system lies in its advanced automatic laser filter, delivering transformative benefits:
1. Labor Cost Reduction: Eliminate the costly downtime and manual labor associated with traditional manual screen changers. The self-cleaning laser filter automatically removes impurities, ensuring continuous, uninterrupted production and maximizing overall line efficiency.
2. Exceptional Longevity: Disc Mesh is made of high-strength chrome-molybdenum steel. Its robust 1.5mm thickness provides outstanding wear resistance and toughness, guaranteeing an exceptionally long service life.
3. Superior Filtration Precision: Thousands of precisely micro-holes on the micron Laser discs enable highly efficient contaminant capture. Leveraging cutting-edge laser technology, filtration precision is adjustable within a range of 80 to 800 microns.
4. High-Frequency Self-Cleaning: Six efficient scraper blades work in concert, creating a continuous cleaning mechanism. They rapidly scrape impurities off the filter surface, ensuring high throughput even during high-impurities load granulation processes.
5. Intelligent Constant-Pressure Operation: Scraper and discharge screw speeds are automatically adjusted in real-time based on melt pressure. This "Constant-Pressure Operation" mode guarantees stable and efficient processing of highly contaminated materials.
6. Minimal Melt Loss: Contaminant purging removes only a very small amount of melt material. Melt loss rates are exceptionally low, typically controlled between 1% and 3%, representing a significant reduction in raw material waste compared to traditional filters.
II. The Melt Pump: Engine of Stability and Output
Core Function: It pressurizes and stabilizes the flow of hot plastic melt delivered from the extruder. It then feeds this melt at a constant pressure and uniform speed to the die head.
How it Works: At its core are a pair of precisely meshing gears, crafted from high-strength alloy steel or specialty materials. The motor-driven active gear rotates the driven gear. Melt is drawn into the gear gaps at the inlet and forcibly conveyed to the outlet under pressure.
Key Benefits Delivered:
1. Significant Output Boost (~20%): Melt pumps surpass extruders in stabilizing melt pressure and flow. Used in series with single-screw or twin-screw extruders, they typically increase overall production line output about 20%.
2. Effective Energy Savings (~25%): Adding a melt pump to a single/twin-screw extruder significantly enhances host performance, enabling higher quality and throughput. Energy consumption per kilogram of processed material can be reduced by about 25%.
3. Precise Process Control: Enables accurate management of critical melt parameters – flow rate, pressure, and temperature – meeting stringent requirements for diverse production processes.
IV. Essential Maintenance:
Ensure peak pump performance and longevity through:
Regular Cleaning: Prevent blockages by routinely cleaning internal passages.
Lubrication: Maintain smooth operation with scheduled lubrication of mechanical components.
Seal Inspection: Periodically check seals to ensure integrity, prevent leaks, and guarantee safety.
