DUP Under water pelletizing system is a special kind of die face hot-cutting system, primarily applied in some materials unable to pelletizing in traditional pelletizing methods, such as strands-cutting, air-cooling (water-ring) die face hot-cutting, or shape of granulate with special requirements, such as micro-size granulate process.

DUP Underwater pelletizing system also is a high-tech pelletizing method. Not only has it successfully solved multi technical difficulties like die face abrasion, thermal equilibrium and automatic control etc., but also it has absorbed foreign advanced technology, which represents a perfect pelletizing solution in such material with high melting point, high viscoelastic and other special requirements.
