Pelletizing Die Plates Pain Points
Uneven temperature
There is a temperature difference between the center and edge of the pelletizing die plate, and the heating partition is not reasonably designed, etc., increasing the temperature difference. Take POM as an example, poor thermal stability, when the temperature difference is greater than ± 10 ℃, resulting in yellowing of the material or particles produce bubbles.
Maintenance difficulties
Underwater pelletizing system only after the shutdown, dismantling the pelletizing die plate after cleaning and washing, consuming a lot of time. The pelletizing knives cannot compensate for the worn pelletizing die plate, and the pellet finishing pass rate continues to decrease, so it has to be shut down for maintenance.
JSW Pelletizing Die Plate Design Innovation
CFD Fluid Dynamics Simulation
Fluid flow distribution in an underwater pelletizing system, calculating and optimizing the taper of die holes, pore size, aspect ratio, etc., to reduce the interference between the melts.
FEA Thermodynamic Simulation
Simulate the temperature field and adjust the heat transfer oil path and heating partition to stabilize the temperature difference between the edge and the center less than ±2℃.
Self-cleaning System
JSW underwater pelletizer, the underwater pelletizing system has a unique high pressure pulsed cleaning system that automatically cleans the residue in the pelletizing system during shutdown. Especially the residual melt in the mold hole of the pelletizing die plate is quickly removed within 5 minutes.
Curing and deterioration are avoided and cleanliness in the mold holes is maintained. Reduction of maintenance downtime by more than 40%.
Advantages of DOMIC Pelletizing Die Plate
Platform Support
Pelletizing die plate design modularity, support 20 kinds of aperture specifications, 50 kinds of flow channel structure of the rapid combination.
Experienced data
Accumulated 2000+ melt parameters, confidence in heat-sensitive products with a pass rate of more than 95%.
Oscillation Compensation
Combined with the follower type pelletizer knife holder, the position of the pelletizing knife is adjusted to compensate for the dynamic swing, maintain the gap, enhance the life of the knife by 2~3 times, and reduce unplanned downtime.
