The right fineness, a guaranteed grain size and reliably cleaned grist at the extrusion interface primarily avoid costly extruder downtimes. Yet they also ensure energy-efficient drying and cooling as well as optimum oil absorption of the finished pellets in the coating process. This in turn has a positive influence on the packaging process and the shelf life of the finished product thanks to the high pellet stability. That’s why we say at Tietjen: It all depends on the grinding.
