The underwater pelletizer is a set of pelletizing system for plastic processing. The material is extruded through the die holes by the screw and then cut into pellets by the high-speed rotating alloy knife. The pellets are transported together with the cooling water to the centrifugal dewatering machine for dewatering, and then enter the reciprocating vibrating screen for air cooling and air conveying to the horizontal mixing barrel for storage and future use. During the pelletizing process, the die surface, material, and cutting knife are all placed in the cooling water. It is particularly suitable for thermoplastic plastics, elastomers, and soft materials with high melt viscosity, such as EVA, SEBS, TPU, etc. This machine adopts automatic control and is simple and convenient to operate.
