First is water strand system. The material come out from die head and then through water tank for cooling, then there is a pelletizer to cut the material to be granules.
Second is water ring system. The material will be cut in the die head, then drop into the water, through water cooling, then come into the Centrifugal dehydrator, remove the moisture. Then through Vibration sieve and silo.
Third is die face hot cutting system. The material will be also cut in the die head. Then through cyclone, cooling the material.
Fourth is air cooling strand system. The die head is same as water strand die. Then use conveyor belt and cooling fan to cooling the material, then there is a pelletizer to cut the material to be granules.
Last is underwater pelletizing system. The die head is under the water, material will be cut in the water and then through Bypass pipe, and drying by the dehydrator.
Different pelletizing systems are suitable for different materials.
