Phase two of the conditioning is – after the pre-Size-Reduction – the Size-Reduction using  Granulators and hammer mills. These machine types are used to crush already pre-crushed particulate materials to the required final size.

Granulators
Among others, the different cutting mills process foils, long profiles up to massive chunks. The material is transported through funnels, rotating rotor knifes and stator knifes to the grinding room.

A large benefit for NEUE HERBOLD granulators is the easy access to the grinding space for cleaning purposes, for material change or for required tool changes. This is important for the reduction of standstill times.

We produce all machines exclusively based on a heavy-duty massive steel construction.

Double diagonal cut – economical and precise
The double diagonal cut guarantees a constant cutting gap for the full work width. Therefore, the cutting mills achieve a high throughput with a low noise development while simultaneously saving energy. In addition, the thermal stress of the material is reduced.

Accessory – Blade adjustment jig
The provided blade adjustment jig permits the precise pre-adjustment of the knifes outside the granulators. Since your employees do no adjust the knifes laboriously in the machine, but under good working conditions by using the adjustment jig outside, this results of course also in an improved work protection action as part of the maintenance of our granulators. The exact fine adjustment of the cutting gap guarantees the efficiency and the throughput performance of the granulators.

Rotor types
Different rotor designs are used to satisfy the diverse scopes of work of the material requirements during the size reduction. The different designs permit the processing of soft, hard and impact resistant plastics.

Pipe shredders
The mostly thick-walled pipes in the pipe shredders are fed to the shredder shafts by a ram. Long and heavy pipes will be transported horizontally into the feed trough using load cranes. Short pipe pieces and pipe wastes from a plastics production can be fed manually by the workers. In addition to our described “traditional” pipe shredders, we also offer for shredding tilting feed hoppers for our granulators, series LM and SM, which are used to release the pipes and to feed them to the shredder unit utilizing the gravity principle.
