defined by the solids diameter, where 50% or 98% of that size is removed via the underflow. The predicted cut size D50actual is the most common parameter used in predicting performance2 and it is evaluated as follows: D50actual = D50base x C1 x C2 x C3 x Cn The D50base value is determined at reference process conditions for a given desander diameter.

to as the cut point. The d50c is the particle size diameter for which 50% by mass reports to the underflow. Solids progressively larger than d50c size have a probability greater than 50% of reporting to the underflow. The ALSI HDC Series is an efficient cyclone, improving separation and reducing short circuiting of fine particles.

Hydrocyclones an overview ScienceDirect Topics

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.

Effects of underflow orifice diameter on the

The underflow orifice diameter is varied in a wide range from 0.04D to 0.32D (i.e. increasing D u /D o from 0.13 to 1.07), where D is the hydrocyclone diameter and D o is the vortex finder diameter. Z represents the axial coordinate along the axial direction of hydrocylone.

underflow. Recent investigations have defined classification as the particle size of which 50% reports to the overflow and 50% to the underflow, or the socalled D50 C point. Figure 3 shows the typical relationship between particle diameter and the percent recovered to underflow. The portion of the curve near the 50% recovery level is quite

that the effect of the underflowtothroughput ratio and the influence of the solids concentration on cut size are both considered. Massarani (1997) proposed Eq.(5) for prediction of the underflowtothroughput ratio: C U L C RB D = (5) where D U is the underflow diameter and B and C are constants for a given cyclone design.
