Hamburg Dresdner Maschinenfabriken GmbH has some detailed information on why their 5 roll refiners are packed with innovation. The video is professionally made to a high standard and explains a number of innovations incorporated into their machines.
The machines address quality issues using differentials in the roll design so that the roller gap can be adjusted on the fly without interruption. Temperature management via water cooling is also done on a roll-by-roll basis.
HDM employ special cameras and different coloured lighting to increase contrast on the live production and identify adjustments that are required in real-time.
