Water ring granulation

Water ring granulation

One of the popular plastic recycling machines belongs to the category of granulation system. The line system of the plastic water ring pelletizing machine consists of a die, a water circulation space, a pelletizing machine, a flushing channel, a centrifugal hydro extractor and a circulating water cooling system. 

Granules are melted and discharged through the extruder, then discharged through the die. During unloading, plastic materials are cut by high-speed rotating blades and the plastic granules are shaken off; after which the granules are cooled and discharged to the water circulation space by means of a circulating water film. Using this flushing channel of the water ring pelletizing system to transport plastic pellets to the centrifugal extractor can not only prevent the adhesion of the plastic pellets, but also act as a cooling process. 

The plastic granules are generally round-flat, cylindrical or spherical.  Plastima works exclusively with Tecnova in this area. For questions about Waterring granulation, you can reach us via the contact page.
