For the production of almost all thermoplastics up to throughput rates of approx. 15 t/h
The water ring pelletizers from Coperion have been in successful operation for many years. They are the result of long years of development work and are suitable for the pelletizing of most thermoplastics, including filled and reinforced products.
In water ring pelletizers, the cooling and transport medium, water, does not come into contact with the die plate. The circulating knives cut the melt strands and fling the hot molten pellets into the circulating water ring. The water flow conveys the pellets out of the pelletizer hood.
Water ring pelletizers have a very compact design and feature low investment and operating costs as well as a simple start-up process.
Special features and advantages of the Water Ring Pelletizer WRG
- Simple start-up process
- Even die plate temperature
- No freezing of bores at low hole throughput
- Uniform pellets with simple die plate design
- Low pressure build-up of the die plate
- Nozzle geometry is widely variable
- No cavitation on the die plate
- Low investment costs
- Low operating costs, among other things due to low energy requirements for heating and drive, low wear, low-cost spare parts and simple operation
- All parts are salt bath-resistant
