Granulator SM

Design of NEUE HERBOLD granulators

The rotors of the NEUE HERBOLD granulators type SM are equipped with double cross cutting technique. Both the rotating knives, as well as the stator blades in the mill housing are placed to each other at an angle. This technique ensures a targeted constant gap over the entire wide of the working surface and also ensures effective cutting. Simultaneously, the noise level is significantly reduced.

Housed in pillow block bearings and separate from the grinding chamber is the rotor shaft . A secure separation from the material to be crushed, and the prevention of leakage of dust particles from the grinding chamber is thereby ensured. By shatterproof welded steel construction of the mill housing, this holds in continuous operation the exceptional stress. Optionally, the housing can be lined with replaceable wear plates.

Alternatively, these as wet execution (wet granulator / wash mill) available.

Applications of NEUE HERBOLD granulators

To be emphasized are the diverse applications of these granulators. These mills can be equipped with different rotors. Suitable rotor variants are available and can be used for:

size reduction of massive start-up lumps
size reduction of massive profiles
size reduction of bottle crates
size reduction of massive purgings
size reduction of PA-fibers
size reduction of rubber bales
size reduction of film packets
size reduction of general plastic scrap with extremely wall thicknesses
size reduction of voluminous hollow parts such as containers and crates

The different needs of a modern recycling plant to be covered by this type of mill.

Advantages of NEUE HERBOLD granulators

universal application useage
reduced space requirement due to compact design
energy-saving size reduction
low noise level due to double-cross cutting knife configuration
easy cleaning due to “clam shell opening” characteristics
higher through put rates
reduced down time for rotor and stator knife replacement due to pre-adjusted knives

Blade adjustment jig

An adjustment tool for presetting outside the machine is supplied. This is used for simple setting and thus to shorten the downtime for configurations.

For the performance of the granulator and the accurate and precise blade adjustment of the cutting gap is essential.

The mill size, rotor type and the material being processed are important factors for the correct size of the cutting gap.
