A high efficiency small diameter hydrocyclone for separating liquid/liquid constituents of a mixture. An effective separation portion L e of the hydrocyclone separation chamber begins at a small diameter throat D T where acceleration and velocity of the mixture cease to increase. This effective portion L e ends at the underflow outlet from the separation chamber, and has an area to volume ...

process using hydrocyclones justia A DorrClone hydrocyclone that can be used in the present invention, comprises three basic members a vortex member, a conical member and a apex member. This hydrocyclone is also related to disk or nozzle centrifuges, and both of them are intended to separate heavies and lights in liquid by application of ...

the wall. On the other hand, a lower feed density will allow the smaller, lighter particles to sink, reducing the cut point. Therefore operating the cyclones at high feed % solids will reduce separation efficiency and result in a coarser overflow, as the drag force is increased on each particle causing the particles to remain nearer the centre.

The interaction between particle density and cyclone size is crucial for selecting hydrocyclone size but not clearly understood. This paper presents a numerical study on the effect of particle density on the multiphase flows and performance of hydrocyclones with respect to cyclone size by the recently developed twofluid model.

The numerical results show that the separation efficiency of particles decreases with the decrease of particle density, and light coarse particles tend to be misplaced at the overflow outlet while ultrafine particles bypass the separation in proportion to the water split. These results are in line with the experimental observations.

Q is the total volumetric flow into the cyclones. Efficiency Curves. If the user selects the User d 50, Krebs, Plitt or Nageswararao models, they may choose the Efficiency Curve equation that will be used to calculate the solids size distribution across the cyclone. The common forms of the Efficiency Curves are the RosinRammler and Lynch curves.

Finally, the effect of particle size on hydrocyclone performance has been studied. It was found that the grade efficiency and number of particle that exit from underflow of the hydrocyclone is increased when bigger particles is used. A series of experiments has been carried out in a laboratory with a hydrocyclone.

Hydrocyclones. Hydrocyclones, or more simply Cyclones, and variations such as McLanahan Separators™ are used in a variety of applications, including classification, desliming, fines recovery, densifying and dewatering. They can be used in industries such as sand, aggregates, coal, industrial minerals, hard rock mining and more.
