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. This plastic extrusion equipment for sale can also be matched with drawing strip cold cutting and water ring hot cutting.
