Replacement of Nitrogen Street
Liquid nitrogen and vacuum insulated pipes
To cool the product inside the hammer mill, the temperature is measured inside the mill. When the temperature is too high, liquid nitrogen is dosed into the mill. The current nitrogen street did no longer meet the requirements. Therefore, a new one was engineered and installed.
At large, the safety in the factory was improved. The pipes were completely vacuum insulated. Finally, less nitrogen was used because of the improved rain valve.
