The granulators of the GSL 300/400 and GSL 300/800 range are
primarily intended for grinding scrap mouldings and sprues from the
injection and blow moulding sector.
In addition to all the important advantages and features described for the
GSL 180 range, the GSL 300/400 and GSL 300/800 slow running machines are
especially suitable for larger mouldings such as car door liners, bumpers or
hollow bodies.
The V shaped arrangement of the staggered rotor blades holds pre-cut
material in the center of the cutting chamber. This prevents material
sticking to the side walls and considerably reduces wear on the grinding
chamber walls when processing fibre and glass reinforced plastics. The
staggered rotor blades means only one blade cuts at once thus increasing the
cutting torque.
The rotor is equipped with special knives. The curvature of the specially
profiled rotor knives ensures a constant cutting circle after resharpening,
maintaining the cutting gap. Awkward knife adjustment is no longer necessary.
Downtime for knife changes is therefore reduced. The GSL stator knives can
be turned 4 times and can also be resharpened.
Sturdy rotor system
The rotor shaft has bearings at each end and the shaft diameter is designed
for the largest rotor width to enable use of a modular assembly across the
width range. Staggered rotor blades means that only one blade cuts at once
thus increasing the cutting torque. All of the machines in this range are
therefore suitable for grinding more solid materials and thicker walled
sprues.
Quick Snap System
The new ZERMA Quick Snap System allows the lower front plate section to be
easily removed for granulator cleaning. The lower front plate section is held
in position by two sturdy lever clamps. An electical limit switch prevents
the operation of the machine when this lower front plate is removed. The
rotor outboard bearing is mounted in the fixed upper front plate section.
Good accessibility
The granulators can be safety opened in just a few steps and without the use
of tools. The feed hopper is hinged and can be pivotted back. After removing
the lower front plate section and the suction trough, the machine becomes
easily accessible ready for quick cleaning in case of colour or material
change.
