Optimizing Hydrocyclone Separation Processes
The mixture [slurry pulp] is injected into the hydrocyclone in such a way as to create the vortex and, depending upon the relative densities of the two phases, the centrifugal acceleration will cause the dispersed phase to move away from or towards the central core of the vortex.

Hydrocyclone Separator
For hydrocyclone separation to be effective, the cyclone must be installed vertically, with the sedimentation tank placed directly under the cyclone. There are however applications where the cyclone can be installed at an angle, but this will be to reach specific objectives like a coarser cut point or more consistent underflow densities.

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.

The Top 5 Things You Need To Know About Hydrocyclones
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.
