Due to the Quick snap fasteners used
on the GSL series machines, the ma-
chines can be opened for cleaning
and maintenance quickly without the
need for special tools.
The curvature of the specially profiled
rotor knives ensures a constant cut-
ting radius after re-sharpening thus
maintaining the original cutting gap.
Awkward knife adjustment is no lon-
ger necessary.

The GSL slow speed granulators of
the 300 series are mainly used in in-
jection and blow molding processes
as beside the press machines to grind
runners and sprues. But they can be
used as low noise central granulators
for small throughput requirements as
well. The stronger design of the 300
series GSLs allow them to be used for
stronger and thicker materials while
offering the same advantages regar-
ding low noise and dust as the smaller
GSL machines. All GSL models can be
equipped with a built in blower sys-
tem in case a vacuum loading system
is not available, or to transport the
ground material to bags for storage.
Staggered rotor blades create an in-
dividual blade cut thus increasing the
cutting torque. All of the machines in
this series are therefore suitable for
grinding more solid materials and thi-
cker walled sprues.

The slow speed granulators in the GSL 300 range feature a staggered 300 mm diameter rotor with widths ranging from 400 to 800 mm. The rotor is directly driven by a geared motor. The low rotor speed reduces the noise level of the
machine and creates less dust while grinding. The special design knives of the GSL series can be sharpened easily and do not need adjustment afterwards.The material is fed via a sound absorbing feed hopper that can be tailored to fit various applications and feeding ways. Depending on the requirements the machines can be fitted with a wide variety of hoppers, they are mounted on eitherlow or high level base frames with matching suction bins or bag filling adapters.
Quick snap fasteners and hand screws make access to the machine for cleaningand maintenance fast and easy.
