Applications
Neue Herbold SX series granulators are specially designed for extremely high output
applications. The application spectrum ranges from film, tangled or bunched tapes and
bands, PP big bags, crates or other hollow containers, to the processing of
BOPP / BOPET / PP
in-line and off-line film extrusion lines. When utilizing a 800 mm (32 in.) rotor diameter
in conjunction with a 2000 mm (79 in.) rotor width and 315 kw (425 hp) drive motor
depending on the specific screen size through put rates of 15,000 kgs/h (33,000
lbs/h) can
be achieved.
Design
SX series granulators are designed with rotor and stator knives that are “V“ or
chevron formed counter angled to each other producing a true scissors type cutting
action.
This design results in a cleaner more uniform granulate and reduced heat build up in the
granulate. Double angle cut also reduces noise emissions and energy
consumption. All
knives are straight sharpening and require no special knife re-sharpening
fixture. All
cutting knives are pre-adjusted to the proper size gap outside the granulator with the use
of the knife setting fixture which creates a constant gap between rotor blade
circumference and screen resulting in reduced friction and therefore less thermal stress
of the material. Knife changes can be accomplished 60% quicker and safer then adjusting
knives within the granulator. The bearings of the rotor shaft are mounted within solid
steel housings (not castings) which offer more reliable service and eliminate any chance
for the housings to crack or break under heavy shock loads. As opposed to flanged mounted
bearings, outboard mounting prevents dust/fines from fouling the bearing nor grease from
contaminating the granulate. Outboard mounting provides for a quieter and cooler
operation. Improved rotor designs eliminate any chance for the rotor knives to lift or
loosen during heavy shock loads. The knife bolts attach to a removable and replaceable
threaded clamp. The rotor flights nor the knife carrier are threaded preventing
unnecessary drilling and tapping to repair stripped threads. The totally welded housing
can also be equipped with replaceable wear plates when operating with high impact or
abrasive material.
Advantages
- extremely high through put rates
- 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
- reduced down time for rotor and stator knife replacement due to pre-adjusted knives
