Applications of NEUE HERBOLD granulators

With the NEUE HERBOLD Profile Granulator of the LP series, it is possible for the size reduction of thick, long pipes and profiles. The horizontal feed allows the processing long profiles or pipes without deflection and without sawing.

The machine of the LP series are in the crushing of PVC profile waste such as Window profile rods used.

The profile granulators in the LP series are especially designed for the horizontal feeding of profiles with a maximum length of 6000 mm. The features and advantages of this series is the results in easy machine placement to include situation next to the extrusion line.

Design of NEUE HERBOLD granulators

Equipped are the NEUE HERBOLD Granulators LP series with a “double cross cutting geometry”. In mill housing the rotating and inclined knives work against the stator blade tilted. This cutting technique, it is possible to obtain an accurate average gap over the entire working width and a powerful low-cut at the same time low-noise operation.

Alternatively, in sealed form this series is available for the use in washing plants.

By separating the outer rotor shaft mounted from the grinding chamber without danger foreclosure is ensured to size reduction. The extreme loads keeps the welded and robust housing mill stand. Ensures the double cross cutting that the profiles are fed automatically by the multiple blade equipped rotor. Material is fed here by hand or via a feed with a roller feeder.

With the NEUE HERBOLD Pipe Granulator SR series, it is possible for the size reduction of thick, long pipes and profiles.

Blade adjustment jig

The adjustment of the rotor and stator takes place outside the machine in a specially designed setting gauge. The adjusting screws in the rotor and in the mill housing are fixed at delivery that adjustment screws in the cutting blade to be adjusted according to the regrinding state. The adjustments to the cutting blade can be performed during operation of the granulator.

To preset outside the machine (with rotors with adjustable blades) an adjustment is provided, which leads to simplification of the knife adjustment and shorten machine downtime when changing knives. The correct and careful adjustment of the cutting gap is critical to the performance of the granulator.
