Water slide strand pelletizing system

Water slide strand pelletizing system

Specific granulating method:

The Granulating methods nowadays are classified according to the cooling method and state of polymer at cutting. The granulating methods based on their own processing characters with specific granulating equipment are suitable for different materials.

Application of water slide cutting:

The plastic granulating line mainly includes strand cutting granulating process, under water granulating line, water ring granulating line, water ring granulating line and centrifugal granulating ling. For water slide system, the water bath will be replaced. 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. The de-watered pellets will be lifted at the top of the dryer. The pelletizing with water slide system can also be called as "wet cut" strand pelletizing.

Advantages of strand pelletizing

• less potential for strand broken

• relatively better cooling efficiency than strand cutting 

Advantages and Disadvantages of Strand Pelletizing

Totally understanding the strand pelletizing process is conducive to figuring out whether the process fits the production condition or not.

As a universal granulating method, the strand pelletizing has following advantages:

• low equipment cost

• easy maintenance

• suitable for most of the materials

Disadvantages are listed in comparison with other pelletizing methods such as water ring or under water pelletizing :

• Relatively low automation grad

• high energy consumption

• more labor power needed
