GSL 300/400 and GSL 300/800 series slow speed granulators, now stocked by CTS Plastics Machinery , are intended primarily for grinding scrap mouldings and sprues in the injection and blow moulding industries.
These granulators offer similar advantages and features as the GSL 180 range, although their slow running speed makes them particularly well suited for use with larger mouldings such as car door liners, bumpers and hollow bodies.
They feature staggered rotor blades that are arranged in a V shape, holding pre-cut material in the centre of the cutting to prevent material sticking to the side walls.
This also considerably reduces wear on grinding chamber walls when processing fibre and glass reinforced plastics.
In addition, the staggered layout of the rotor blades on GSL 300/400 and GSL 300/800 series granulators means that only one blade cuts at a time, thus increasing overall cutting torque.
