Hydrocyclone
The principle of hydrocycloning is based on the tangential injection flow process: a mix of liquid solids into the cylindrical part of the hydrocyclone, called the head. The centrifugal force applied to this mix induces a separation between the particles in the cylindrical and conical parts of the hydrocyclone.

Spiral classifier or hydrocyclone
A friend familiar with this told me the main problem with spiral classifiers is the cut size is directly proportional to retention time (flow rate, Stoke's law, that sort of thing). To get a fine cut size requires flow of almost zero = the finer you want to cut, the lower the flow and density required. Hitzrot, H. W. wrote a great paper in Society for Mining, Metallurgy & …
