Pelletizing Principle of The Underwater Pelletizing System


The molten plastic material is pressurized and transported to the pelletizing die by an extruder or a melt pump. The end face of the pelletizing die and the cutter are enclosed in a pelletizing water chamber with flowing water. The extruded molten plastic is instantaneously cut by the cutter and is cooled and formed by the process of water flowing through the mold surface. It is quickly transported to the rotating drum centrifugal dryer for solid-liquid separation, and uniform qualified particles are sent out from the centrifugal dehydrator to complete the pelletizing and forming work. In the pelletizing process, the kinetic energy consumed by the melt material cutting is low, and the force and surface tension of the extrusion equipment on the melt material make the appearance of the cut plastic particles uniform, round, and without sharp angles. The application of the fluid dilute phase transport mechanism in the system equipment makes the probability of re-bonding of the molten plastic particles during the transportation and cooling process extremely low, and the adhesion of cutting debris on the surface of the particles is avoided.


Industrial Underwater Pelletizing System

In recent years, with the continuous emergence of new plastic materials, the higher quality requirements in precision injection molding, extrusion, and other fields, and the steadily rising labor costs, traditional plastic pellet raw material manufacturers have placed high hopes on advanced granulation equipment. Nowadays, thanks to the efforts of extruder and compounding equipment manufacturers, the advanced granulation equipment that was once completely dependent on imports, and the price and use cost are unattainable-the underwater pelletizing system equipment is gradually moving towards localized manufacturing. Underwater pelletizing system equipment has been widely used across fields with its unique pelletizing mechanism and function.


Advantages of the industrial underwater pelletizing system

1. The advanced underwater pelletizing system equipment technology ensures that the polymer melt is stably cooled and cut in water so that the pellets have unparalleled consistency and appearance quality.

2. The advanced underwater pelletizing technology can be applied to many kinds of melt materials.

3. The closed pelletizing process realizes environmentally friendly production.

4. Simplified structure, taking up very little production site space.

5. The underwater pelletizing system has higher production efficiency and economy.
