HYDROCYCLONES By Richard A. Arterburn For many years, hydrocyclones, commonly referred to as cyclones, have been extensively utilized in the classification of particles in comminution circuits. The practical range of classification for cyclones is 40 microns to 400 microns, with some remote applications as fine as 5 microns or as coarse as 1000 ...

An innovative axial hydrocyclone separator was designed in which a guide vane was installed to replace a conventional tangential inlet, potentially aggravating inlet turbulence.

An axial spiral inlet hydrocyclone was proposed for the in situ desanding of NGH. The effectof spiral inlet pitch, the heads, the turns, and the steady flow cone on the flow field characteristics,

The equipment price of hydrocyclone is lower than that of spiral classifier. However, in addition to its own equipment, the hydrocyclone requires a series of necessary auxiliary equipment in the grading process, such as distributors, valves, pumps, etc., which increases some equipment investment. In terms of maintenance, the wear parts of ...

Figure 1: Schematic principle of the hydrocyclone [3] Slurry is fed under pressure through the tangential feed inlet. The resulting swirl on the outer side of the hydrocyclone moves towards and leaves trough the apex. The built swirl in the inner side of the hydrocyclone moves upwards and leaves trough the vortex finder (see Figure 1).

The laminar spiral inlet geometry design provides a natural flow path into the ® hydrocyclone. Its unique shape has no sharp edges or square corners and allows the feed stream to blend smoothly with rotating slurry inside the chamber.

Common spiral classifiers include high type and submerged type. The high type is usually used for coarse-grain classification, and the diameter of the overflow particle size of the classification is generally greater than 0.15mm. The submerged type is suitable for fine particle classification, and the overflow particl…

A spiral classifier and a hydrocyclone are the two main classification equipment. For decades, the spiral classifier has been widely used in ore dressing plants as first-generation grading equipment. As second-generation grading equipment, hydrocyclones quickly occupy a place in the grading equipment of the concentrator due to their small footprint and high …

Introduction. Hydrocyclones, also simply called "Cyclones", separate particles according to size and/or density using centrifugal force to accelerate the settling rate of solid particles.They are cylindrical-conical shaped devices with one entrance and two exits and consist of a feed box, feed inlet, vortex finder, optional feedbox extension, cone section(s) and spigot.
