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.
hydrocyclone technology has been shown to provide extremely high throughput operation using an entirely passive design without the need for precise control over inlet flow rates to maintain high separation efficiency. For example, a commercial hydrocyclone with 125 mm chamber diameter operating at inlet pressures up to 124 kPa, corresponding to ...

A novel hydrocyclone design fabricated and tested for iron ore slimes beneficiation. • Optimised performance found with 10° cone of novel cyclone for silica slurry. • Air-core elimination by rod insertion results an adverse effect on its separation. • Hydrocyclone performance found very sensitive to inserted rod's offset from center •
For hydrocyclone of diameter 500 mm the convergence angle is 12°. HC 500/12° hydrocyclone is equipped with composite anti-abrasive linings based on silicon carbide ensuring significant elongation of the equipment lifetime. Basing on the new hydrocyclone an innovative classification system consisting of Hc 500/12°hydrocyclones was built [4].
Both the rotation of micro-droplets along the spiral trajectories and the intense eddy diffusion in a hydrocyclone contribute to the extraction intensification.
Here is a hydrocyclone sizing calculator with immediate access to all design equations needed for your hydrocyclone design calculation in an online XLS spreadsheet format. Based on first principles of hydrocyclone theory and equations, this quasi design software lets you enter all cyclone design parameters such as cut size, D50, D60 …
Closely related to the centrifuge device, whose separation force is achievable by rotation of the entire equipment, the hydrocyclone instead depends upon the movement of the centrifugal forces within the fluids to allow for adequate particle separation. In 1891, E. Bretney patented the first hydrocyclone, and from this time through 1948, a ...
4 variables such as liquid viscosity also affect this correction.-1.43 C 1 = 53-V (Eq. 4) 53 Where C 1 = Correction for the influence of cyclone feed concentration. V = Percent solids by volume of
The coupling effect between particle movement and hydrocyclone separation is most pronounced when the density ratio of particles to oil ranges from 0.94 to 1. The separation performance experiments show that compared to CHC, HCCP can improve by 2.12–8.22 percentage points, and HCCP not only enhances separation …
Hydrocyclone is an important industrial solids–liquid separation equipment. Although widely used nowadays, the selection and design of hydrocyclones are still empirical and experience based. Although quite a few hydrocyclone models had been developed over the years, the validity of these models for practical applications was still …
In a hydrocyclone, a slurry enters through a tangential inlet, giving rise to a vortex in the stationary body. ... Stegowski and Leclerc (2002) have used 64 Cu with a half-life of 12.7 h to investigate the classification of copper ore slurries. Methods such as PIV and LDV track the average velocity distributions of particles, as opposed to ...
Fig. 6.c shows, since copper is the most abundant element in the WPCBs, that the copper amount was increased up to 20 ± 4.4 wt.% by the hydrocyclone. Furthermore, the remarkable result was achieved after the second step of separation (U2.2P3 by DGM) reaching 40 ± 4 wt.% Cu (⁓ three times higher) at the end of the …
A friend familiar with this told me the main problem with spiral classifiers is the cut size is directly proportional to retention time (flow rate, Stoke's law, that sort of thing). To get a fine cut size requires flow of almost zero = the finer you want to cut, the lower the flow and density required. Hitzrot, H. W. wrote a great paper in Society for Mining, Metallurgy & …
The principle of copper ore flotation is to utilize the physical and chemical properties differences between copper minerals and other impurity minerals, and to combine copper minerals with by adding appropriate flotation agents and ing agents, thereby separating them from other impurity minerals. Specifically, the flotation agent can …
