The extruded strands enter a water slide, in which spray nozzles cool the strands and provide a water flow taking the strands towards the pelletizer. The strand and water jointly go into the pelletizer. The water will be away from the strand at the cutting position in pelletizer. After cutting, the pellets fall into water. The pellets can get further cooling. The pellets with water enter the centrifugal dryer from the dryer bottom.

Carrying with the advantages of strand cutting like low equipment cost and easy maintenance. The water slide strand cutting has its own advantages such as: better strand broken protection and better cooling efficiency. The water slide is for plastic recycling widely applied.

The precise processing temperature is always the basic requirement on parallel twin screw granulating line. With water cooling and bronze heater, the whole extrusion process will keep a constant temperature, which set on control cabinet. What’s more the high precise temperature sensors play an important role in background.
