Product Overview
Nanjing Haisi Extrusion Equipment Co., Ltd. offers the highly efficient SJ-150 kneader single screw compounding and pelletizing production line. This equipment is specifically engineered for processing highly filled masterbatches. This advanced two-stage extrusion system perfectly combines high-intensity intensive mixing with stable single-screw pressure extrusion, delivering excellent dispersion for formulas with extremely high inorganic powder loading.
Advanced Process Configuration
The production line features a seamless, automated two-stage design to maximize compounding efficiency:
High-Efficiency Pre-Stage Kneader: Raw materials and high-percentage fillers are intensively sheared and mixed in the closed chamber of the kneader, achieving optimal micro-dispersion and polymer wetting.
Conical Twin-Screw Side Feeder: The hot compounded mass from the kneader drops directly into the conical twin-screw side feeding unit. This unit forces the material uniformly into the single screw extruder, completely eliminating bridging or clogging issues common in traditional feeders.
SJ-150 Single Screw Extruder: Featuring an optimized profile for high-filler formulas, the extruder handles steady pressure building, cooling, and extrusion without causing material degradation.
New Type Water-Ring Pelletizing System: Equipped with an upgraded water-ring die-face cutter. The precise blade-to-die alignment combined with an optimized water circulation system ensures high-efficiency cooling and perfectly uniform, non-stick granule production.
Technical Advantages
Massive and Stable Output: The heavy-duty SJ-150 processing system delivers a reliable, high-volume production capacity of 600 to 700 kg/h, drastically lowering energy consumption per ton.
Superior High Loading Capacity: Leveraging the intensive mixing power of the kneader, this line easily processes compounding formulas with exceptionally high ratios of inorganic fillers.
Continuous Fully Automated Operation: The entire chain from kneading to feeding, extrusion, and pelletizing operates in a synchronized closed loop, maximizing factory floor efficiency.
Typical Applications
This heavy-duty granulation line is ideal for manufacturing:
Highly filled PE and PP Calcium Carbonate (CaCO3) masterbatches
Talc filled functional masterbatches
Barium Sulfate (BaSO4) high-density compounding
Highly concentrated flame-retardant masterbatches
