Description
ECON is the leading provider of underwater pelletizing technology with thermally insulated die plates. The die plate is fixed on the heated carrier body. The thermal insulation ensures that the melt in the die holes will not "freeze". ECON pelletizers are not sensitive to fluctuations in output, thus making the pelletizing process extremely reliable and guaranteeing high operating efficiency.
In addition, the compact and clearly designed ECON water treatment and drying system is an effective solution for drying the pellets. The continuous filtration of process water ensures low maintenance requirements. Because the pellet dryer is easily accessible and free of dead spots, material or color changes can be done quickly. The complete pelletizing line can be easily adapted to different production conditions, thus increasing your flexibility.

Function
The underwater pelletizing system consists of a polymer diverter valve, a pelletizing unit, a water treatment and drying system, and an electrical control system.
- When started, the melt flow is directed downwards by the polymer diverter valve. Once a constant melt flow is given, the stream is redirected and the die plate is rinsed with melt.
- As soon as the melt is continuously emerging from each hole, the stream is once again directed downwards. The die plate is cleaned and the pelletizer housing is fixed to the pelletizing head by means of the hydraulic lock.
- Afterward, the melt is directed to the pelletizing head with the die plate installed and the emerging melt strands are pelletized underwater. The pellets are then moved to the water treatment and drying system by the process water. The separator then removes any potential lumps.
- In the pre-dewatering unit, the pellets are separated from the process water and conveyed to the centrifugal dryer. The centrifugal forces in the dryer and the special arrangement of the blades propel the pellets upwards and simultaneously separate the residual water via screens.
- The pellets exit the system at top and move on tot the next step
- The process water is collected in the water tank, filtered, and recirculated to the process. A cooling circuit with a plate heat exchanger is integrated to control the process water temperature.
