Adaptable
Cutting Chamber Allows Granulators to Handle a
Wider Variety of Scrap
New
CBW and CGW Series granulators feature exchangeable
back plates that modify the cutting chamber from
a super-tangential to a restricted tangential
configuration. This means that the same granulator
can handle the bulky thin-walled parts, bottles,
sheet and film that normally require tangential
feeding, or heavy-wall parts and profiles and
sprues/runners that are more suited to a conventional
straight-drop feed. This versatility allows processors
to achieve maximum throughput and a more consistent
and uniform regrind from a granulator that is
smaller overall.
The
new granulators also have a large swing-away front-panel
door that provides quick and easy access to the
cutting chamber. The screen cradle and granulate
catch bin are actually mounted on the door —
in front of the rotor, rather than underneath
— so they swing out of the way as the door
is opened. This unique design significantly reduces
time needed for cleanout and material changeover,
and simplifies access to the blades if maintenance
is required.
CBW
granulators can process up to 500 lb/hr using
10-inch-diameter rotors that are 12, 18 or 24
inches wide. The CGW units are larger, with a
14-inch cutting circle and rotor widths of 18,
24, 36 inches. Maximum throughput for the CGW
is 1000 lb/hr. Both come with a 3-blade open rotor
as standard, however the CGW is also available
with an optional 5-blade open rotor for increased
throughput capacity or to restrict the aggressiveness
of the rotor action.
When
set up in the super-tangential configuration,
the CGW granulators have a huge, 17-inch feed
opening, which can accept even the bulkiest scrap.
Adding the restrictor plate to the back of the
cutting chamber reduces the opening to 14 inches.
A third bed knife can also be added along with
an extended rotor shaft and secondary flywheel
to maximize throughput of even tough heavy-walled
parts. The smaller CBW units have feed openings
of 14 inches and 10 inches for super-tangential
and restricted configurations respectively.
Other
options include a blower system for regrind evacuation,
which can include fines separation or elutriation.
Elutriation allows processor to adjust the percentage
of fines retained in the regrind to maximize the
amount of material reused while ensuring process
consistency and product quality.
The
wide swing-away front door provides the industry’s
fastest cutting-chamber access for cleaning and
maintenance. Other features that add to user convenience
include easy adjustment of the gap between the
rotor and fixed bed knives, ensuring a constant
cutting circle for increased throughput and high-quality,
uniform regrind. These granulators have hinged
feed trays, double-wall sound-proofed hoppers
and optional integral sound enclosures to reduce
operating noise.
