GSL - Slow speed granulator

Schneidmühlen

The slow speed granulators in the GSL range are mainly used in injection and blow molding processes as beside the press machines to grind runners, sprues and rejected products as well.

GSL 180
Mainly used in injection and blow molding processes as beside the press machines to grind runners and sprues
GSL 300
Can be used as low noise central granulators for small throughput requirements as well.

Advantages of the slow speed granulators:

  • Direct driven staggered rotor
  • Special knife design makes adjustment unnecessary
  • Easy access for maintenance and cleaning
  • Slow rotor speed creates less noise and dust
  • Easily customizable to suit different applications

Technical details

Special knives make adjustment work unnecessary

The curvature of the specially profiled rotor knives ensures a constant cutting circle maintaining the cutting gap after resharpening. 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 modular rotor star system allows combined with the staggered rotor blades ensure maximum cutting torque by reducing the number of concurrent cuts.

Quick-Snap-System

The ZERMA Quick Snap System allows the lower front plate section to be easily removed for cleaning and screen access. An electrical limit switch prevents the operation of the machine when this lower front plate is removed.

Easy accessibility

The already easy, comfortable and tool-less accessibility of the GSL series has been improved even more. Changes to the suction trough and screen holder make maintenance work easier and faster.


Slow speed granulator GSL 180

GSL 180

The slow speed granulators in the GSL 180 range feature a staggered 180 mm diameter rotor with widths ranging from 180 to 430 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 either low 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 cleaning and maintenance fast and easy.

Applications

The GSL slow speed granulators of the 180 series are mainly used in injection and blow molding processes as beside the press machines to grind runners and sprues.
The resulting granules are then immediately reintroduced into the production process. The machines can be used for rejected products in the inline recycling process as well.
Different hopper and base frame designs make it possible to integrate the machine with most types of injection molding machines and robots.

Slow speed granulator GSL 300

GSL 300

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 either low 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 cleaning and maintenance fast and easy.

Applications

The GSL slow speed granulators of the 300 series are mainly used in injection 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 regarding low noise and dust as the smaller GSL machines.
All GSL models can be equipped with a built in blower system in case a vacuum loading system is not available, or to transport the ground material to bags for storage.
