Basics of a Hydrocyclone. Hydrocyclones (also referred to as cyclones) are an efficient way to separate slurries. With no moving parts, they depend on the feed pressure, or velocity, into the cyclone to generate a centripetal force. This centripetal force allows the cyclone to separate coarse or dense particles from fine particles.
The use of a hydrocyclone is an efficient solution to avoid clogging and thus reduce maintenance (compared to traditional cartridge filters) or repair interventions. The Nice-based company Hectron has a range of hydrocyclones that are effective tools for separating sand from water. These devices are widely used in many fields.
Hydrocyclone Working Principle. The centre of this spiral is called the VORTEX. The purpose of the apex is to cause internal pressure for the cyclone and to create a vortex that extends all of the way to the top of the cyclone. In all hydrocyclones there are two outlets, one for the coarse material, this is the APEX, and the other for the …

In this case, the iron ore is composed predominantly of hematite and about 10% magnetite. The gangue minerals include quartz, feldspar, chlorite, olivine, and pyrite. Because the ore contained complex gangue minerals, reverse flotation failed in previous tests. Download : Download full-size image; Figure 9.15.
Thus, this novel hydrocyclone has three outlets, namely the overflow dilute liquid, the underflow concentrated liquid, and clear filtrate. This system enabled higher …
Hydrocyclone is a simple mechanical device, with no moving parts, where solid particles are separated from liquid with very little head loss. As its name describes, it uses a cyclone or tangential injection flow process enhancing the centrifugal forces and moving solids outwards. The dispersed particles, move downwards in a spiral path into an ...

Similarly, Bamrungsri et al. (2008) have used a high-speed camera to record the motion of a dyed oil drop in water in a hydrocyclone. Wang et al. (2008) have also used a high-speed camera to record the motion of a vegetable seed with density of 1140 kg/m 3 in a water hydrocyclone. Two-dimensional trajectories could be plotted by recording the ...

created inside a hydrocyclone depend on the intensity of pres-sure drop in between the conical and the cylindrical portion (Nowakowski et al., 2004). This is because the centrifugal force generated inside a hydrocyclone due to the tangential entry in-creases with decreasing cyclone diameter. The performance of
Adding magnesium olivine to the pellets increased the porosity of incompletely mineralized magnesium olivine. It hindered the recrystallization of hematite particles, which was detrimental to the CCS of the pellets. Bai et al. [10] investigated serpentine minerals' effect on magnesium-containing pellets' consolidation behavior …

To draw a process flow diagram include ball mill and hydrocyclone to grind the olivine, which equipment do we need to add? What is the order of these equipment? Do we need a filter behind overflow stream from hydrocyclone?
Section snippets Review of enhanced-separation hydrocyclone technologies developed by optimizing operating parameters. Generally, the enhanced-separation technologies of hydrocyclones by optimizing operating parameters can be categorized into 5 varieties: (i) feed flow rate; (ii) feed pressure; (iii) feed density …
Thus, the results obtained with the hydrocyclone corresponding to Fig. 12 (a) show that this parameter increases from 86.1% to 92.0% when the spigot diameter changes from 6 to 16 mm. Operating at 200 kPa with the hydrocyclone of smallest body (D = 50 mm, θ = 5 ° and vortex finder diameter of 10 mm) leads to an increase in the value of the ...
A hydrocyclone consists of a cylindrical top with an offset feed inlet pipe, an overflow outlet on top and tapered cone(s) leading down to a small outlet on the bottom. Other parts include external casings that contain the internal pressure and are clamped or bolted together, and internal replaceable liners for wear resistance. ...
The flow pattern inside a hydrocyclone can be described using three velocity components: tangential (θ), axial (z), and radial (r). The tangential velocity shows a Rankine vortex-type rotational behavior as shown in Figure 2. Starting from the hydrocyclone wall, the velocity increases and reaches a maximum. The point where the …
The hydrocyclone did not separate the oil droplets with particle size less than 10 um well, and a large number of oil droplets escaped from the bottom flow under the action of the outer swirl, and the separation efficiency was less than 70%. Therefore, the average particle size of the produced liquid should be greater than 10 um.
The MHC™ Series hydrocyclone's industry leading flow rate creates an optimal flow even with given pressure drops. Wear resistant liners are also incorporated for an increased uptime and extended the lifecycle of the parts overall. With the single component conical section, MHC™ hydrocyclone provides an ease of maintenance reducing downtime.

Description. Evoqua's VAF [TM] brand Hydrocyclone Separators are effective in removing suspended particles from any flow stream of water where the specific gravity (density) of the particle (s) is heavier than the fluid it is in. The more significant the difference in gravity between the water and the particle, the greater the efficiency of ...
Hydrocyclones are used in desliming, degritting, concentration, recovery of solids, clarification, open-circuit classification, and closed-circuit grinding. The hydrocyclone below is used to remove polypropylene powder from a solvent recovery unit. Cyclones can recover powder coatings, dust, chemicals, and catalysts.
The maximum 'pulp density' is usually about 50% solids by weight; above that level small fluctuations in density will seriously affect separation. A coneshaped discharge of 20°–30° reduced angle usually produces optimum conditions for separation. Cyclone control is best obtained by optimising the feed density.
