Special knives make adjustment work unnecessary

The rotor is equipped with special knives. The curvature of the specially profiled rotor knives ensures a constant cutting circle after resharpening, maintaining the cutting gap. Awkward knife adjustment is no longer necessary. 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 rotor shaft has bearings at each end and the shaft diameter is designed for the largest rotor width to enable use of a modular assembly across the width range. Staggered rotor blades means that only one blade cuts at once thus increasing the cutting torque. All of the machines in this range are therefore suitable for grinding more solid materials and thicker walled sprues.

Quick Snap System

The new ZERMA Quick Snap System allows the lower front plate section to be easily removed for granulator cleaning. The lower front plate section is held in position by two sturdy lever clamps. An electical limit switch prevents the operation of the machine when this lower front plate is removed. The rotor outboard bearing is mounted in the fixed upper front plate section.


Good accessibility

The granulators can be safety opened in just a few steps and without the use of tools. The feed hopper is hinged and can be pivotted back. After removing the lower front plate section and the suction trough, the machine becomes easily accessible ready for quick cleaning in case of colour or material change.

The granulators of the GSL range can be equipped with numerous options for the most varied of intended applications. Here are some examples:
