The G-series granulators are intended for applications with higher demands on life span, power, reliability and lower maintenance. They can be used separately as well as within lines processing used passenger car and lorry tyres, alternative fuel production lines, processing of plastics, paper, electronic waste, cables, wood, etc.
The granulators are based on the principle of the cutting action of 3 to 7 rotor head blades opposite two stator blades. Both the stator blades and the rotor blades are replaceable and after the edge becomes blunt, they can be turned over. After that they need to be sharpened or replaced by new ones. The blades are made from high-alloy steel.
The whole inside of the granulator, including parts of the hopper, is lined with HARDOX, which is an abrasion resistant material. The rotor head is also made from HARDOX. That guarantees long life and renewability of the parts. In the lower part of the granulator, under the rotor, there is a screen used for output material calibration. The screen is also made from HARDOX. Some parts which are under high strain are welded with cemented carbide.
The granulator is fitted with its own control system, which doesn’t require much attention on the part of the operator. If it is included in a line, it can also be connected to the central control panel with a PLC control system, which controls the granulator, monitors load and overload, temperature and number of motor operation hours. The granulator is fitted with safety contacts and features according to current standards. If any non-standard regime occurs, the PLC emits a signal and shows an error message or disengages the machine to avoid damage.
The granulator can be supplemented with a cyclone and with pneumatic transport or, for coarser crushed material, with an output screw conveyor, or with a belt conveyor.
