Hydrocyclones are established devices in mechanical process engineering. Despite their more than 150-year history, there are still no generally valid design models. As a result, experimental investigations on separation behavior are still necessary.

In an industrial context in particular, companies publish the separation performance of their products in their data sheets. However, these results are often not comparable with other manufacturers, as each uses individual methods (e.g., different test particles, different test procedures).

In a comprehensive comparative study, we examined cyclones (2-inch inlet diameter) from various international manufacturers on the same test bench, thereby contributing significantly to comparability and facilitating product selection.
