A study by Martinez et al. (2007) revealed that its solids separation efficiency was around 29% with a 18 cm diameter hydrocyclone which increased to 34% when the size of the hydrocyclone was reduced to 5 cm in diameter, which means that its efficiency increases with the decrease in size of the hydrocyclone; however, the high flow rates could ...

Another parameter established for ascertaining the hydrocyclone separation efficiency is d p 90 in the overflow stream, i.e., the biggest particle size in the 90% volume fraction of the particles leaving the hydrocyclone in that stream. This parameter provides an indication of the overall quality of the overflow.

4. A Hydrocyclone can be modified to make a dry underflow while maintaining a high separation efficiency. A Hydrocyclone uses an air core, which forms at the apex and extends up to the vortex finder. The formation of this air core is paramount to making a separation, and if it collapses, the separation efficiency dramatically drops.
