impact of hydrocyclone feed pump on hydrocyclone performance
desired mineral. However the hydrocyclone is a major piece of equipment in the beneficiation process that has no instrumentation for directly measuring its performance. The parameters currently measured – inlet pressure, feed flow rate, feed flow density – are common to the entire hydrocyclone cluster which

The past: A step back in time
Solid/liquid separation performance of hydrocyclones with different cone ... Because the objective of this study is to understand the effects of different cone combinations on the hydrocyclone performance, the characteristics of feed slurry and the operating parameters
When you add water to the feed of the cyclone, the result is the overflow becomes lighter and the underflow becomes heavier. The heavier UNDERFLOW DENSITY will give the ball mill more work to do. This is reflected in a heavier density being fed back into the hydrocyclone feed pump box. Which again changes the hydrocyclone operation performance.
Effect of Volume Fraction on the Performance and Separation Efficiency of a De-oiling Hydrocyclone 154 large, hydrocyclone efficiency drops off. On the other hand, reducing flow rates leads to increase in PDR. An increase in PDR increases the flow split and may marginally increase hydrocyclone efficiency.

A return line was set near the inlet of the pump to manipulatethe feed rate and to avoid the strong impact to thehydrocyclone by the inlet flow. The light dispersion was separated and went back to the tankwith the overflow ...
Hence, this study proposed a two-stage (TS) hydrocyclone, and the effects of the inlet velocity on the TS hydrocyclone were investigated using computational ﬂuid dynamics (CFD). More speciﬁcally, the inﬂuences of the ﬁrst-stage inlet velocity on the second-stage swirling ﬂow ﬁeld and the separation performance were studied.
Even though the influence of solids concentration in the feed on the separation efficiency of hydrocyclones has long been recognized, a systematic research on the change in pressure drop across the hydrocyclone and the latter's separation characteristics has thus far been lacking.

Hence, this study proposed a two-stage (TS) hydrocyclone, and the effects of the inlet velocity on the TS hydrocyclone were investigated using computational fluid dynamics (CFD). More specifically, the influences of the first-stage inlet velocity on the second-stage swirling flow field and the separation performance were studied.

A Hydrocyclone operates at a required pressure, which is usually provided by a pump. Anything that causes instability in the flow rate, as shown by the pressure reading, will affect the performance of the Hydrocyclone. A poorly designed sump can send entrapped air or surges in materials.
CYCLONES 5555 HydroCyclones A typical hydrocyclone consists of a conically shaped vessel, open at its apex (spigot), or underflow, joined to a cylindrical section, which has a tangential feed inlet. The top of the cylindrical section is closed with a plate through which passes an axially mounted overflow pipe.
The experimental setup as shown in Fig. 1 has been used Bendixen and Rickwood (1994) studied the effects of hydro- for the studies of performance characteristic of hydrocyclone cyclones on the integrity of animal and microbial cell.
For a hydrocyclone to work at peak efficiency the volume of slurry and the feed pump delivery pressure must remain constant. If the cyclone feed pump is allowed to SURGE, the up and down pressure will cause poor separation at the point of high and low operating pressure. There is a cycle to a surging pump box that causes this pressure fluctuation.
While many authors have covered the effects of inclination below horizontal on hydrocyclone performance, very few of them investigated hydrocyclones at semi-inverted positions (higher than horizontal). The work of Asomah in particular has inspired development on a new concept which we have called "semi-inverted" hydrocyclone operation.
The third type of classification used in mining is the Hydrocyclone, commonly called a Cyclone. Unlike the others it has no moving parts and is worked in conjunction of another piece of equipment, a pump. To understand the Hydrocyclone Working Principle we must first know its components. Beginning at the top, there is the OVERFLOW DISCHARGE.
performance a 100 mm diameter hydrocyclone Investigate the effect of the feed particle size distri-bution and the feed solids concentration at different cone force ratios on the performance of a 100 mm diameter hydrocyclone Analyse the effect of varying the cone force ratio on the water split to the underflow stream. Experimental set-up
Three runs were performed at a high, moderate and low feed solids concentration, corresponding to 48.8, 40.7 and 31.6% solids, respectively. The results were then used to assess the effect of varying the feed solids concentration on the hydrocyclone performance.
AbstractA critical assessment is presented for the existing numerical models used for the performance prediction of hydrocyclones. As the present discussion indicates, the flow inside a hydrocyclone is quite complex and there have been numerous numerical studies on the flows and the particle motions in hydrocyclone, with a wide range of turbulence and multiphase models tested.
A hydrocyclone is most often used to separate "heavies" from a liquid mixture originating at a centrifugal pump or some other continuous source of pressurized liquid. A hydrocyclone is most likely to be the right choice for processes where "lights" are the greater …

The Hydrocyclone Efficiency Curves are affected by many operating factors such as feed density, apex and vortex sizes and feed pump pressure. These factors will cause your cyclone classification to operate correctly, in roping or spraying mode. Everyone knows or has seen an "Ideal Cyclone Efficiency Curve" VS an actual real life hydrocyclone Efficiency Curves?
