1. Main types of equipment

Process requirements, including difficult operations and the need to produce new products with unconventional rheology and specific usage properties, have led equipment manufacturers to offer increasingly complex mobile or compact agitation-mixing systems with multiple functions or for specific industrial sectors.

These specific devices have not been the subject of numerous scientific publications, which can be compared as in the case of the proximity stirrers analyzed in the theoretical section. . It is therefore difficult to compare their performance according to objective criteria, as manufacturers' technical sales brochures are often all that is available. An arbitrary distinction is made between batch mixers, which are generally vertical, and horizontal systems operating in-line.
