Effect on Separation Efficiency of Cyclones

Cyclone designers have long known that the separation efficiency of tangential inlet cyclones improves with increasing solids loading. Even so, the exact mechanism for this improvement is still not established beyond doubt, in spite of many investigations of the topic. 

We will be returning briefly to the topic of solids loading in swirl tube separators later. Here, we wish to note that a difference exists between the behavior of cyclones with tangential inlets and swirl tubes equipped with inlet vane assemblies, so that the results shown in these figures cannot be applied to swirl tubes.
