ZERMA – GSH 600 & 700 Series

General Description

The heavy duty granulators of the GSH 600 and 700 series offer a wide array of different rotor designs with widths ranging from 800 mm to 1000 mm with a diameter of 600 and 700 mm. The completely welded heavy steel construction is designed to to withstand the most demanding and universal applications. Rotor bearings, knife mounts and rotor shaft are oversized. The standard V-cut creates a high quality regrind 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 bearings reducing the risk of contamination.

Applications

The wide range of rotors and hopper styles allow the GSH machines to be tailored to almost every application in the plastic recycling field.The GSH 600 and 700 granulators are mainly used as large central granulators for in house recycling applications to process large thick walled parts in one step or as a second step granulator after a shredder to reach higher throughput rates. When used to grind light materials, such as bottles the throughput can be greatly increased with the addition of a ZERMA force feeding device. For abrasive, contaminated or highly filled materials the machines can be equipped with special wear protections, such as hard facing of the rotor and housing and key parts manufactured from highly wear resistant steels.

Details:

The easily removable deflector wedge acts as a third stator blade and can be used to adjust the aggressiveness 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.
