Granule production: Easy and cost-effective, Part 2

There are various ways of producing granules from fine-grained substances or dusts. The authors compare the relatively simple and cost-effective processes of granulation in the oblique intensive mixer, disk pelletizers and drum pelletizers. Here, theory only assumes marginal importance. On the contrary, a long series of examples shows in which applications mixing granulators respectively disk and drum granulators are used worldwide today and yield a profit to the users over decades. A further process described enables straightforward water-free agglomeration using organic solvents, as well as the production of high-density granules from a suspension (Evactherm process). Similarly to mixing, which cannot be calculated but needs to be observed and investigated in experiments, the process of granulation can only be approached via practical studies.
