GSH heavy duty granulators for processing large thick walled parts and sprues

Manufacturer: Zerma Germany

  • Knives are adjusted outside the machine
  • Specially developed deflector wedge
  • Wide choice of rotors
  • Well thought out housing design
  • Strong Welded Steel construction
  • Oversized outboard bearings

The heavy duty granulators of the GSH350, GSH500, GSH600 and GSH700 series offer a wide array of different rotor designs with width ranging from 500 mm (800 mm) to 1000 mm with a diameter of 350 mm, 500 mm, 600 mm and 700 mm. Rotor bearings, knife mounts, rotor shaft and the completely welded heavy duty construction is designed to withstand the most demanding and universal applications. The standard V-cut creates a high quality reprint with a very low percentage of fines in the output material. The removable third stator blade is acting as a deflector wedge and allows the machine to be quickly adjusted to different application scenarios. Other standard features include easily replaceable wear plates in the cutting chamber as well as outboard bearing reducing the risk of contamination.

The wide range of rotors and hopper styles allow the GSH granulators to be tailored to almost every application in the plastic recycling field. The GSH350, GSH500, GSH600 and GSH700 are mainly used as large central granulators to process large thick walled parts in one step or as a second step granulator after a shredder to reach higher throughput rates. For abrasive and contaminated materials the machine can be equipped with special wear protection, such as hard facing of the rotor and housing.

  • The easily removable deflector wedge acts as a third stator blade and can be used to adjust the aggressiveness off of the rotor at the first cutting point.
  • The GSH granulators are available with different rotor options to fit different applications, all rotors feature the V-cut technology creating a high quality regrind.
  • The heavy duty bearings are separated from the cutting chamber to avoid lubricants entering the cutting chamber and bearing failure due to material contamination in the bearings.
  • Rotor and stator knives are pre-set outside the machine prior to installation in a supplied fixture. This makes awkward adjustment outside the machine unnecessary.
