Slow speed granulator ZERMA GSL 300
The low-speed granulators in the GSL series have been specially developed for
injection molding applications. In most cases, the regrind obtained is fed directly
back into the production process. With their numerous hopper and base frame
variants, the GSL granulators can be integrated into almost all injection molding
machines and handling systems.
General description
The GSL 300 series low-speed granulators have been specially developed for the size reduction of sprues and rejects from injection and blow molding.They are also suitable as central granulators for smaller throughput quantities. The GSL 300 series offers the well-known advantages of low-speed machines, such as low noise emissions and low-dust grinding material.
The low-speed granulators in the GSL 300 series have a rotor diameter of 300 mm and working widths of 400 to 800 mm.
The V-arrangement of the rotor knives keeps the material to be shredded in center of the rotor, which considerably reduces wear on the grinding chamber walls. Due to the staggered arrangement of the rotor disks, only individual knives are in use at any one time, which means that a higher cutting force is always available.
The machines in this series can be optionally equipped with an suction system, to fill the material into for example bags.
Options
GSL 300/800 with roller feed
for the shredding of, for example Punching grids in inline recycling.
Good accessibility
All components (hopper, suction tray,
front panel) can be removed without
tools, ensuring optimum access for
maintenance and cleaning work.
High chassis
with adapter for filling the ground material into a mobile, 60 l roll container.
GSL 300/400 with integrated
extraction system
GSL 300-Details (Preview)
Special knives make adjustment work unnecessary
This shape of the rotor knives ensures a constant cutting circle even after regrinding, so that the required cutting gap between the rotor and stator knives is maintained. The stator knives can be reversed 4 times and can also be reground.
The rotor
The staggered rotor stars mean that only individual blades are used, which increases the cutting force. The rotor shaft is mounted on bearings on both sides. The low rotor speed of 150 rpm ensures a low noise level and low-dust ground material.
Drive via a powerful gear motor
The directly flange-mounted geared
motor ensures a high torque.
Inclined hopper
Inclined hopper in sandwich design without integrated baffle plates for feeding long or bulky parts.
