This document discusses types of classifiers used in mineral processing. There are two main types - wet classification and dry classification. Wet classifiers separate minerals based on differences in settling velocities in water, and include spiral classifiers, hydraulic classifiers, and hydrocyclones.
To deal with the small particle sizes, hydrocyclones with smaller body diameters, known as mini-hydrocyclones or micro-hydrocyclones, are often employed in food and bioproduct processing compared to mineral processing to achieve a satisfactory separation and smaller cut size.

The hydrocyclone is an important device used in mineral processing beneficiation circuits for classification of mineral slurries by particle size. One input stream is separated into two output streams; an underflow of coarse particles that undergo additional grinding, and an overflow stream of finer particles that typically goes directly into a ...
Hydrocyclones were invented in the late 1800s and became widely used in mineral processing because they are relatively inexpensive, process high volumes, take up minimal floor space and have no moving parts. Hydrocyclones are commonly used for desliming, dewatering and sizing -4mesh (5mm) particles.
Hydrocyclones are useful for the removal of suspended solids from ballast waters by liquid–solid and liquid–liquid separation. This technology is also effective for the dewatering of microalgae cultures. ... The hydrocyclone is a widely used classifier in the mineral-processing industry. It is installed in close circuit between the grinding ...

The separation inside Hydrocyclones are the standard classifiers used in wet closed grinding circuits in mineral processing plants and are chosen due to their simple design, low cost, easy operation, and low maintenance requirements.
Since the early 1940s, hydrocyclones have commonly been used in the mineral industry. Due to the simple design, high capacity, low maintenance, low operating cost and small dimensions of the device, hydrocyclones have become an important equipment for the chemical, mineral, coal and powder processing industries.
Compared with these two classifiers, the hydrocyclone has a better classification effect when processing finer-grained materials (the separation particle size range is generally 0.3-0.01mm).
Is the air core formation inside a hydrocyclone is needed or not? Got confused as many research papers suggest to minimize the air core diameter by several design modifications within the hydrocyclone. On the contrary air core is necessary to carry the fine particles through the overflow.
It is generally recognized the small particle size separations require small diameter hydrocyclones. For geometrically equivalent cyclones, the mean particle size separation (d50) is a function of the cyclone diameter, i.e., ... mineral applications require a separation whereby a material finer than the desired cut point reports to the overflow ...
