SJ100 Underwater Cutting Granulating Machine for PE PP Film

Underwater Cutting Granulating Machine Description:

Underwater cutting granulating machine is mainly used to quickly cool molten plastics and cut them into uniform particles. Unlike traditional air-cooled granulators, the core process of underwater cutting granulator is completed underwater, and rapid cooling and cutting are integrated through water media. They can process a variety of thermoplastic materials such as polyethylene (PE), polypropylene (PP), and polyester (PET).

Underwater cutting granulating line is widely used in the production of recycled plastics, chemical fibers, and engineering plastics. They are especially suitable for high-volume, continuous production scenarios, and can significantly improve particle quality and production efficiency.

Underwater granulator is widely used in the production of recycled plastics, chemical fibers, and engineering plastics. They are especially suitable for high-yield, continuous production scenarios, and can significantly improve the quality of particles and production efficiency.

The outstanding advantage of underwater granulating line lies in their unique cooling and cutting design.

First, the water flow directly contacts the high-temperature melt, quickly solidifies the surface of the particles, avoids adhesion, and ensures that the shape of the particles is uniform and regular.

Second, closed underwater cutting effectively isolates oxygen, reduces material oxidation, and ensures the color and performance of the finished product.

In addition, the underwater cutting granulating machine is equipped with an automated control system that can adjust parameters such as water temperature and cutting speed in real time to ensure production stability. Its modular structure design is easy to maintain, while supporting energy-saving mode, reducing water and energy consumption, and conforming to the trend of green manufacturing.

Underwater Granulating  Line Working Principle:

When the underwater granulator is running, the molten plastic is pushed to the multi-hole die head by the extruder, and after forming a strip material, it is instantly cut into particles by the high-speed rotating blade underwater. The circulating cooling water in the cutting chamber simultaneously completes the cooling and particle transportation, and then the water-particle separation is achieved through centrifugal dehydration or vibration screening.

The whole process achieves efficient cooling and environmentally friendly operation through a closed-loop water circulation system, and the water temperature control accuracy directly affects the crystallinity and density of the particles. This principle combines the synergy of heat conduction and fluid dynamics to ensure a balance between high production capacity and low energy consumption.
