PRODUCT CENTER
Underwater Pelletizer
Rongpai underwater pelletizers are specially designed for producing a wide range of polymer-based thermoplastics, primarily producing spherical pellets, with output up to 12,000 kg/h.
View Details
Pellet Drying & Water Processing Systems
Depending on production requirements, pellet dryers can be installed next to the water tank or independently around the silo, both being practical solutions in actual production.
View Details
Melt Diverter Valve
The melt diverter valve serves as the interface between the underwater pelletizing system and upstream equipment, enabling connection or disconnection of the pelletizing process from upstream processes.

By-pass
Premature or delayed entry of process water into the cutting chamber can lead to unsuccessful startup or even significant production losses in underwater pelletizing operations.

Screen Changer
Removing melt impurities is a critical step before the pelletizing process. The screen changer filters out contaminants in the melt, ensuring material purity, stabilizing production, and improving product quality.
