Gran-Excalibur (GXC Series) Heavy Duty Granulators are designed for high throughput size reduction of larger sized products in a single pass. These machines are also ideal for secondary granulation when positioned behind pre-shredders in various types of recycling systems. Incorporating various different methods of wear protection such as replaceable wear plates and resistant surface coatings, the GXC machines are well suited to processing abrasive, contaminated materials such as glass filled plastics and dirty films containing sands.  

Standard Features

  ·  Strong welded construction from heavy gauge steel plate

  · Manual, electric and hydraulic chamber opening mechanisms - quick access to the cutting chamber for maintenance and machine cleandowns
  ·  Replaceable wear plates at either end of the rotor shaft
  · Stand Alone Electrical Control Panel - using quality Schneider (Telemecanique) components and Siemens PLC's
  ·  Tested, Approved and Certified to the applicable CE safety standards

GXC Series Rotor Configurations

As standard, GXC series machines are supplied with our open V-Rotor as standard which is suitable for most types of material.  The double shear, V configuration of the forward set blades creates a highly efficient double scissor cut, and encourages material to the centre of the cutting chamber.  This results in reduces power consumption, even blade wear, reduced wear on the chamber sidewalls and optimum throughput.  The open design of the rotor lets material expand and move around and allows good airflow through the machine.  This minimizes heat build up and production of fines.   Granulators can be supplied with 3, 5, 7 or 9 rows of rotor blades depending on the model.  A rear set V-rotor design (known as the VS-Rotor) is also available for certain, lighter duty applications.

The C-Rotor is a heavy duty, high inertia, semi-closed design intended for demanding applications.  The larger quantity of individual blades are held by strong supporting segments and can be replaced piece by piece if required.  This design creates a cascade cutting effect which is well suited for processing hard or thick materials and is also a popular choice when granulating profiles.  The C-rotor is available with 3,5 or 7 staggered rows of blades depending on the model.
