Surface Area Of Hydrocyclones

Hydrocyclones are generally operated vertically with the spigot at the lower end, hence the coarse product is called the underflow and the fine product, leaving the vortex finder, the overflow. Figure 1 schematically shows the principal flow and design features of a typical hydrocyclone: the two vortices, the tangential feed inlet and the axial outlets.

Hydrocyclones have come to dominate classification when dealing with fine particle sizes in closed grinding circuits (<200 µm). However, recent developments in screen technology (Chapter 8) have renewed interest in using screens in grinding circuits.Screens separate on the basis of size and are not directly influenced by the density spread in the feed minerals.

Hydrocyclones can be used for separation by size of the suspended solid particles or by particle density. Typical examples include solids classification duties in mining and industrial applications. For enabling efficient operation of hydrocyclones the form of the discharge through the underflow outlet is important.

A hydrocyclone (often referred to by the shortened form cyclone) is a device to classify, separate or sort particles in a liquid suspension based on the ratio of their centripetal force to fluid resistance.This ratio is high for dense (where separation by density is required) and coarse (where separation by size is required) particles, and low for light and fine particles.

The Sizing & Selection of Hydrocyclones. THE SIZING AND SELECTION OF HYDROCYCLONES By Richard A. Arterburn For many years, hydrocyclones, Figure 5 or calculated from Equation 3. For example, a 25.4 cm (10 in.) diameter cyclone has a base D50 C point of 24 microns. D50 C(base) = 2.84 x D 0.66 (Eq. 3) Where D = Cyclone diameter in cm.

A hydrocyclone has a generally conical chamber, a tangential inlet at the large end of said chamber and an axially aligned accept outlet located centrally of said large end. A reject passage is located at the apex end of said chamber the inwardly facing surface of said reject passage being provided with means defining a spiral shaped groove along and within which portions of the reject ...

Surface area and volume are calculated for any three-dimensional geometrical shape. The surface area of any given object is the area or region occupied by the surface of the object. Whereas volume is the amount of space available in an object. In geometry, there are different shapes and sizes such as sphere, cube, cuboid, cone, cylinder, etc.
