roll is designed as a fixed roll and the other one as a floating roll. The required comminution pressure is transmitted via the floating roll. The high-pressure interparticle comminu-tion produces compacted cakes of material containing a high proportion of fines and coarser particles showing extensive crack-ing. These compacted cakes are disinte-

Mathematical models of high-pressure grinding rolls (HPGR) have attracted great attention, owing to their role in optimization of operating machines as well as in the design and selection of new ones.
Globally, between 1-3% of animal feed is lost during the milling process, which equates to approximately 30 million tonnes of feed wasted each year. Optimising moisture content in feed is key to ensuring safe, consistent, high-quality animal feed. Water or moisture, whether natural or added into feed, is an important feed ingredient.
