PE PP Water Ring Pelletizing Line|PE PP granulation line,
The PE PP Water Ring Pelletizing Line, 由广东宝路盛精密机械有限公司研发制造, 多年的研发设计经验研发的, relies on profound plastic extrusion and recycling technologies, with high efficiency and stable performance as its core advantages. The PE PP Pelletizing Recycling System provides global customers with customized one-stop plastic pelletizing solutions.
Blesson's water ring pelletizing unit:
PP PE water ring pelletizing unit is applicable to LDPE, 高密度聚乙烯, LLDPE, PP films (whole pieces or crushed materials) with a moisture content of ≤5% and impurities of ≤1%.
Core configuration: Single-screw main extruder + Hydraulic automatic non-stop screen changer +Water ring pelletizing → high capacity of 600–650 kg/h.
Water Ring Pelletizing Line stands as the preferred solution for plastic pelletizing plants when compared with air-cooled and underwater pelletizing systems — pellets are cooled in water immediately after being discharged from the die head, a process that delivers higher efficiency and better pellet morphology. This is exactly the core advantage of our Water Ring Pelletizing Line. The Water Ring Hot Cut Plastic Recycling Pelletizer is ideal equipment for LDPE (Low-Density Polyethylene)/LLDPE (Linear Low-Density Polyethylene) film recycling, PE (Polyethylene)/PP (Polypropylene) pellet regeneration, plastic modification and compounding, 等.
Advantages of Blesson's Water Ring Pelletizing Line:
- The Water Ring Pelletizing Machine adopts CE-certified components, supports customization, and features precise engineering design.
- One-stop solutions for the Water Ring Pelletizing Line: including process consultation, formula guidance, equipment installation, technical training and after-sales service.
- 描述
The water ring hot cut pelletizing line, a sophisticated result of Blesson’s meticulous development with innovative R&D as its core driving force since its establishment, relies on industry-leading technical configurations. It has not only redefined the benchmark for plastic recycling efficiency, but also, by virtue of customized services for recycled plastic equipment and in-depth adaptation to processing scenarios, the water ring pelletizing machine has become the preferred equipment for numerous enterprises to enhance product competitiveness and achieve environmental protection and efficiency improvement. In the fierce market competition, the water ring hot-cut pelletizing line continues to occupy a leading position and serves as an ideal partner in the industry.
What is plastic pelletizing?
Plastic pelletizing is the process of converting waste PE/PP films, scraps, or rigid plastics into reusable pellets. Water ring pelletizing machine can be widely applied in the production of blown films, injection-molded products, pipes, 包装, and other goods. With efficient and stable pelletizing equipment, enterprises can not only significantly reduce raw material costs and improve recycling efficiency, but also comply with environmental regulations and achieve closed-loop utilization of factory waste. It is an ideal choice to promote sustainable production and enhance profit margins.

Technical Highlights of Water Ring Hot Cut Pelletizing Lines
1. Two-stage Extrusion System
**Single-screw Main Extruder**
Dual-Venting Design:High-efficiency devolatilization resolves bubble issues in high-volatility materials (e.g., recycled plastics), enhancing product density by 5-8%.
Wear-Resistant Screw: 38CrMoAlA nitrided steel + wear-resistant alloy coating on flight edges (rare in China). Nitriding depth of 0.4-0.7mm extends service life by 50% compared to standard nitrided screws.
Intelligent Temperature Control: 9-zone independent heating + zonal cooling (fan/water combination). Precise ±1°C temperature regulation reduces energy consumption by 15%.
Water ring pelletizer’s solution: Processes high-viscosity materials like LDPE/HDPE/PP with throughput up to 600-800kg/h and waste rate <0.3%.
Single-screw Main Extruder Wear-resistant screw
**Secondary Extruder**
Pressure-Boosting Design: Optimized short L/D ratio (12:1) for melt pressure homogenization. Paired with dual-column water-cooled screen changer (3000cm² filtration area), pressure fluctuation <2MPa during screen changes.
Modular Die Head: 90 independent temperature-controlled discharge ports enable rapid product specification changes (30 minutes vs. industry average 2 小时).
Water ring pelletizer’s advantage: Seamless integration with the main extruder ensures high-precision pelletizing (particle size deviation ±0.2mm).
Single-screw Secondary Extruder Pelletizing extrusion die
2. Die Face Hot-Cutting Unit
Three-Station Cantilever Cutterhead: Driven by 2.2kW variable-frequency motor with stepless speed regulation (0-3000rpm). Supports on-line blade replacement (downtime <5 minutes).
304 Stainless Steel Water Ring: Corrosion-resistant design triples service life compared to carbon steel.
Closed-Loop Water Cooling: Maintains water temperature ≤15°C, reducing water consumption by 40% (only 2m³/h required).
Water ring pelletizer’s solution: Delivers pellet roundness >95%, ideal for high-end applications like transparent and medical-grade materials.
3. Vacuum System – Energy-Saving Auxiliary
Dual-Stage Anti-Backflow Design: Water-ring vacuum pump (5.5kW) + condensate tank achieves -0.095MPa vacuum level, removing >90% of volatiles.
Water ring pelletizer’s solution: Minimizes material degradation and enhances melt strength, especially for LLDPE.
Vacuum unit Dehydrator
4. Vertical Dewatering Machine
Direct-Drive Centrifugal Technology: 5.5kW motor-driven system reduces moisture content to <0.5% (vs. industry average 1-2%), eliminating the need for additional drying.
