Underwater pelletizing system

Almost all polymers can be processed in different sizes of particles, suitable for PE, PP, PS, TR, TPE, TPR, TPV, PET, PVC, EVA, ABS, calcium mother, calcium masterbatch, carbon black masterbatch materials.

Electricity

Underwater pelletizing technology is a kind of "die surface pelletizing". When the homogeneous high temperature molten material enters the die runner from the end of the upstream equipment (reaction kettle, screw extruder, mixing equipment, etc.),

  Equipment Introduction: Underwater pelletizing system generally consists of driving valve, die head, pelletizing head, water circulation system and fittings, dehydration drying system, vibration filtration system and control system .Underwater pelletizing technology is a kind of "die surface pelletizing". When the homogeneous high temperature molten material enters the die runner from the end of the upstream equipment (reaction kettle, screw extruder, mixing equipment, etc.),

  the material is cut into droplets by pelletizer blade with high speed while it leaves the mould and mould hole and then enters the processing water.

  Due to the temperature difference between the molten droplet polymer and the processing water, the droplets solidify and form particles similiar to the sphere. This kind of "first hot pelletizing and then water cooling" granulation method determines that it can be very good for the granulation operations of materials with molten state of poor strength, high viscosity and high heat sensitivity .
