Technical Introduction:

The underwater pelletizing system generally consists of a starting valve, a die head, a pelletizing head, a water circulation system and fittings, a dehydration and drying system, a vibration filtration system, and a control system. Underwater pelletizing technology belongs to a type of "die surface hot cutting". When a uniform high-temperature molten material enters the die flow channel from the end of upstream equipment (reaction kettle, screw extruder, mixing equipment, etc.), the material is immediately cut into droplets by the high-speed rotating pelletizer blade and enters the processing water. Due to the physical characteristics of maximizing the specific surface area of particles and the temperature difference between the melted droplet polymer and the processing water, the droplets solidify and form particles that are close to spherical shapes. This granulation method of "hot cutting first and then water cooling" determines that it can effectively handle granulation operations for materials with poor melt strength, high viscosity, and high thermal sensitivity.

Particle quality advantage:

1. Optimize particle shape to achieve a smooth and uniform surface;

2. High particle density and good fluidity;

3. Eliminate the phenomenon of particle oxidation;

4. Less adhesion phenomenon;

5. Production and operational advantages:

1) Fully automated continuous production; One click startup, convenient and fast.

2) Shorten curing time, reduce footprint and cooling water demand; Energy conservation and environmental protection.

3) Fully enclosed production, clean environment;

4) Low noise and no dust pollution.
