Water ring granulating line belongs to the concept of hot cut pelletizing method. Polymer exiting extruder passes into an annular die. At the die face, the molten polymer will be cut by flexible blades in air. After cutting, molten pellets are thrown into a ring of falling water. In water the pellets are cooled and transported. The cutting, cooling and transporting condition define different pelletizing methods and dispose unique pelletizing equipment.

Water ring granulating system produce rounded but flat pellets with the shape of similarly aspirin tablets. It is because of the specific cutting process.
As the polymer exits from the multiple holes, the rotating knives cut the polymer and throw outward into the water ring chamber. The water cools the pellets and transports them to vibration sieve filtration to check the quality of the pellets. Only the pellets with stipulated size can be transported to the centrifugal dryer for drying. According to the character of the polymer, the cooling process could be improved.
