Cyclones and hydrocyclones are widely used for gas–solid and liquid–solid particle separations, respectively. The key feature is the presence of a centrifugal field. Equilibrium zone concept is one of the most used approaches for equipment design. This work revisits the design equations for nonspherical particles and compares design results ...

The ratio of the lower (d н) and upper (d в) drain pipe diameters is one of the most important parameters in the hydrocyclone calculations.The d в /d н ratio defines the condensed and clarified product ratio at the port outlet. Numerically, this relation can be represented by an approximate formula: Q н /Q в = 1.13·(d н /d в)³. Where: Q н – condensed product flow in the lower ...
You can calculate both, and compare the results on the chart. Both sheets are set up with the same layout, so data can be copied between sheets easily. 3.00 The efficiency calculation requires particle size data, cyclone dimensions, and physical property data for the gas and the solids. The calculation assumes that the size distribution of the ...
(4) and (5). These Figures show, for Bradley and Rietema hydrocyclones respectively, the reduced cut size as a function of flow rate, for some values of pressure drop and cyclone diameter. It can be observed that for the same pressure drop Rietema hydrocyclones produce flow rates 2 to 3 times higher than Bradley hydrocyclones of the same size.
A classifying cyclone system is needed to achieve a 150 micron (100 mesh) separation. The total volumetric flow rate to the system is 5000 gpm at a solids content of 5% by weight (Ï p=1.02). At an average relative solids density of 1.3, the solids mass flow rate equates to 64 tons/hr.

Hydrocyclones are an important class of solid/liquid separation equipments. In this work, three Bradley hydrocyclones with 15,30 and 60 mm diameters were used. Aqueous suspensions of calcium carbonate, with volumetric concentration ranging from 0% to 10% were tested. Based on the experimental results, it was possible to obtain correlations for ...

hydrodynamics acting in hydrocyclones are very complex and hard to be theoretical modelled being common the adoption of empiric models based in laboratories tests to estimate hydrocyclones performance. The most used model for hydrocyclone corrected cut size calculation was proposed by Plitt (1976) and over the years many revisions and

Mathematical simulation of hydrocyclones: K. A. Pericleous Runs were performed for a series of monosized particles, ranging from 1 to 15 p, with particle loadings of 1% and 10% of the feed by weight. A run was also performed with three coexisting particle sizes, to investigate the effect of interaction between them.
HYDROCYCLONES. The hydrocyclone is a simple piece of equipment that uses fluid pressure to generate centrifugal force and a flow pattern which can separate particles or droplets from a liquid medium. These particles or droplets must have a sufficiently different density relative to the medium in order to achieve separation.

Hydrocyclones, otherwise known as centrifugal cleaners, vortex cleaners, or centricleaners, came into widespread use in the paper industry in the 1950s.Prior to this, hydrocyclones were commonly used in the mining industry for separations. A hydrocyclone consists of a cylindrical-conical vessel with the inlet flow introduced tangentially at the top (Figure 8).
The calculation method proposed is reported in [Dirgo] 4.2 Calculate the cyclone dimensions. If you design a new cyclone, chose one of the standard geometry in table 1 and assume a diameter D. If you test an existing cyclone, determine the different ratios for the actual equipment you are evaluating. All the individual length (a, b, S ...

The separation capability when various hydrocyclones are compared is expressed as d 50 cut-size . The d 50 cut-size represents the minimum size of the particles that are at least 50% removed by the cyclone. These particles are then separated as slurry at the bottom of the cyclone.

Hydrocyclones are engineered to do a solids split based on particle size. The coarser/larger particles tend to be sent to the underflow, while the finer/smaller particles are carried to the overflow. To determine how good of a split your Hydrocyclone makes, it is necessary to do a solids balance based on gradation.
