Unique Housing Design

The housing cutting chamber is divided across the centre line which allows the upper section to be easily opened hydraulically.

The screen is positioned in a front mounted easy access screen cradle which is separate from the upper cutting chamber and also opens hydraulically.

Heavy Duty Outboard Rotor Bearings

The over-sized pedestal type rotor bearings are mounted outside the cutting chamber in solid steel housings. They are designed for minimal service and built for demanding applications. The outboard bearings eliminate material contamination through lubricant and eliminate pre-mature bearing failure through material contamination in the bearings. Outboard bearings is also an advantage during wet granulating operation.


Flywheel

To increase rotor inertia an auxiliary flywheel is available as option on the non-driven rotor shaft side. All rotor shafts in the GSH series are standard with the extended rotor shaft for flywheel installation.


Utmost Operational Reliability

The granulators in the GSH series are manufactured to current European Union machine requirements and are fully CE certified. Machine safety is ensured through time-delay bolts with safety switches, hydraulic safety check valves, etc.


Easy Rotor/Stator Knife Adjustment

Rotor and stator knives are pre-set outside the granulator in a supplied bench-top fixture prior to installation. Awkward adjustments inside the machine are no longer necessary. The knives are manufactured from heavy duty high quality toll steel and can be re-sharpened numerous times.

Integrated Deflection Wedge Knife

A removable adaptor carrying a third stator knife, termed the deflection wedge, can be installed to alter the in-feed cross section and control the aggressiveness of the rotor at the first cutting point. This will eliminate rotor blocking during extreme applications. When the deflection wedge is removed the granulator is applicable for large voluminous parts such as hollow parts, crates, and other high volume parts.

Superior "V" Type Chevron Cutting Geometry

The GSH series offers a complete range of rotor variations which are all built with the unique "V" type chevron cutting technology. The "V" cut action generates the material concentration around the centre of the rotor and evenly distributes it along the entire rotor length. The typical material conveyance to the cutting chamber side through conventional fully slanted rotor knives is eliminated. The centred and evenly distributed material prevents cutting chamber side wall material build up and side wall material melt down.

The rotor knives are not bolted into the rotor stars as with conventional type rotors but utilize threaded rotor knife backing plates. Therefore eliminating the drill out removal of broken or stripped bolts from the rotor stars.
