Overview of HKY/SKY Two Stage Extruder


HKY/SKY series two-stage extrusion system: the first stage is HK or SK series high speed and high torque co-rotating twin screw extruder, the second stage is single screw extruder to form a two-stage compound extrusion system. The system combines twin screw high speed, strong mixing with single screw low speed, low temperature and weak shearing characteristics to enhance advantages and avoid disadvantages. It is the preferred model for mixing and modifying heat-sensitive and shearing-sensitive materials efficiently nowadays. The main granulation methods are air-cooled hot cutting and eccentric water mist granulation. They can also be matched with drawing strip cold cutting and water ring hot cutting.


Applications of HKY/SKY Two Stage Extruder:


  • PVC Cable Material and XLPE Peroxide Crosslinking Material

  • Soft PVC Medical Material

  • Hard PVC Products

  • EVA Foamed Shoe Bottom Material

  • PE Low Smoke Halogen Free Resistance Fuel


Main features of HKY/SKY Two Stage Extruder:


  • Plasticization, mixing and homogenization of twin screw processing section

  • Open melt feeding single screw extruder without backpressure, and exhaust and devolatilization can be carried out at the same time.

  • Soft extrusion of materials through the template of single screw extruder

  • Air-cooled granulation, eccentric water mist granulation, stretch granulation and water ring granulation can be selected according to material properties.

  • Smaller power and area

  • Fully automatic raw material mixing and granulation process to reduce labor costs

  • Easy to operate, excellent safety and stability
