The granulator replaces an aging granulator placed in a pit. A belt conveyor with a metal detector is present and must be integrated.
The pipe sections that are taken back from construction sites are roughly cleaned. The further data:

Installation:
The robust RS 8012 granulator (cutting diameter 800 mm, cutting width 1.200 mm) is ideal for grinding thick-walled parts at high throughput rates:
- heavy 7-blade rotor with additional flywheel
- third stationary blade as pre-cutting blade increases the throughput and reduces current peaks
- cutting chamber armored with replaceable wear plates
- EnergySave motor controller for the 160 kW drive motor: This not only provides a soft start, but also calculates the most favourable motor voltage for the most efficient operating condition by continuously recording the performance data (current, voltage, cos phi).
When comparing the granulator with the performance data of the previous granulator, the RS 8012 achieved a 35 % higher throughput while saving 25 % electricity.
This outstanding result is due to the energy-efficient cutting geometry and the intelligent motor controller.
