Granulating systemWater ring
The water ring pelletizer system consists of a die, water circulation room, pelletizer, flushing channel, centrifugal hydroextractor and a circulating water-cooling system. Plastic raw materials are melted and discharged through the extruder, then discharged through the die. During discharge, plastic materials are cut by high-speed rotating blades and the plastic pellets are shaken off; after which the pellets are cooled and carried off by circulating water film to the water circulation room. Using the flushing channel to transport plastic pellets to the centrifugal extractor can not only prevent adhesion of the plastic pellets but also acts as a cooling process. The plastic pellets are generally round-flat, cylindrical or ball shaped.
The unique features of this system include: The die surface does not make direct contact with water, low costs from die and blade wear, as well as producing pellets of consistent sizes and shapes after passing through the water circulation (die surface) pelletizer.
It is currently mainly used for plastic materials such as LDPE, HDPE, PP etc..
