» GSH 350 & 500 Series

General Description

The heavy duty granulators of the GSH 350 and 500 series offer a wide array of different rotor designs with widths ranging from 500 mm to 1000 mm with a diameter of 350 and 500 mm respectively. 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 350 and 500 granulators are mainly used as central granulators for in house recycling applications to process 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.

» 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.

» GSH 800 Series

General Description

The heavy duty granulators of the GSH 800 series offer a wide array of different rotor designs with widths ranging from 1200 mm to 2000 mm with a diameter of 800 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, mainly with high throughput requirements. The GSH 800 series can be used to grind large thick walled parts down to a granule in one step, or be used as a second step granulator after a ZXS shredder to reach very high 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:

Rotor and stator knives are pre-set outside the granulator in a supplied bench-top fixture prior to installation. Awk- ward adjustments inside the machine are no longer necessary.
The granulators can be tailored to fit various applications, for example with oversized suction troughs in order to achieve a very high output.The GSH 1100 series comes standard with wide H-style rotors available with 9,11 or 13 rows of rotor blades ensuring a high quality output.
For abrasive applications the GSH granulators can be equipped with rotors with key parts manufactured from highly wear resistant steel as well as weld on hard facing.
