The NGR water ring, hot die pelletizer is applicable for all types of thermoplastic melts (except for PA 6.6, PET and PPT with MFI > 100).
Working principle >>
As determined by the system, during HD pelletizing (hot die), the melted plastic strands produced by the extruder are chopped into pellets by rotating cutting blades. The pellets are then cooled by a water ring and removed.
The new NGR HD pelletizer automatically maintains uniform blade pressure. The combination of a simple, rigid cutting head and a pneumatic, axially adjustable cutter shaft allows precise adjustment by means of a manometer or an electronic pressure regulator (option) to a blade pressure that ensures minimum wear. Accordingly, no separate setting of the individual blades is required.
Advantages >>
NGR hot die pelletizer has been further developed and apart from an excellent price-performance ratio, offers rapid cutter setting, constant pressure and a tangible reduction in employee workloads! Your advantages at a glance:
- Very simple and therefore rapid setting of the blades and pressure.
- Alterations to blade pressure during operation.
- Extremely long blade life.
- Simple blade design.
- Retention of the defined pressure even after cutting blade changes.
- Especially easy manual opening and closing.
- Small dimensions – particularly in the case of types with high outputs.
- Tangible reductions in employee burdens and shorter plant downtimes due to the prolongation of the maintenance intervals and the shortening of servicing times.
- Insensitivity to throughput changes.
Features |Types >>
NGR HD pelletizer are available in various sizes for outputs of 20 – 2000 kg/h [44 – 4400 lbs/h]. Various perforated plate and cutter head designs are available for differing applications. As an option, the NGR HD pelletizer can be equipped with a blade wear indicator and an electronic cutter blade adjustment.
