Underwater Pelletizer
Under water pelletizer is widely used in plastic granulating industry, it can process almost 90% of different plastics compounding & granulating. The automatic cutting and complicated controlling, alarm sytem allow customer to save manpower and waste material, moreover, the final granule is in better shape and uniform size which is easier to be accepted on the market.
As a professional producer of underwater pelletizing systems, Cowell has extensive knowledge and expertise in various polymer processing techniques that can help you get better products. With our unique heat insulation and die plate design, it can process a wide range of polymers, such as thermoplastics, hot melt, masterbatches, engineering plastics etc.

Composition Of The Underwater Pelletizer
1. Diverter
2. Underwater die head
3. Pelletizer
4. Tempered water system
5. By-pass pipe
The by-pass pipe unit is also an important part of UWG. The diameter of the pipe decides the water flow rate that is need for the material and the capacity. With different circulation designs, the whole system could be operated perfectly.
6. Centrifuge dryer
7. Smart controlling system
The whole system is controlled by PLC and HMI. With one key start/stop. Interlock with upstream equipment. Temperature, rotation speed, pressure, flow rate display, data storage, alarm analysis, one key reset, etc.
Typical Applications:
Masterbatches
Thermoplastics: TPE, TPR, TPV,etc
Hot melt: EVA, TPU, PA etc
Biodegradable materials: PLA, PBAT, etc
