Normalisation of the efficiency curves of hydrocyclone

1999-1-1  As the feed solids are distributed over a range of sizes, we need a complete efficiency curve to describe the performance of the hydrocyclones. A characteristic feature of the 'gross' or actual efficiency curves of hydrocyclones is that as the particle size approaches zero the efficiency approaches the water recovery.

DATA-BASED PERFORMANCE MODELLING OF

2011-10-31  In this study, a data driven performance characterization model of hydrocyclone has been developed using multiple experimental data set collected from the published literature pertaining to processing of iron ore fines. The cut size, d50, has been determined for a given cyclone operating conditions using Lagrangian interpolation technique. A reduced efficiency curve has been constructed to map the performance and the functional behaviour has been modeled employing three typical distribution functions, namely, Rosin-Rammler, Exponential and Logistic. All pertinent model parameters have been estimated in accordance with the experimental data sets. It has been observed that all these functions fairly mimic the performance of cyclone

The Effect of Feed Solids Concentration on Hydrocyclone

Partition Curves Partition or efficiency curves are used to represent the performance of the hydrocyclone.

Mathematically, the curve is defined by: 3 fCHE3064S Hydrocyclone

The main goal of a hydrocyclone is to produce an underflow with most of the coarse particles and considerably less fine particles than the feed stream, according to its designed cut-off size d 50. The cut-off size is an indicator of the separation performance of a hydrocyclone, and is the ultimate variable to

The Sizing & Selection of Hydrocyclones

2016-2-16  Historically, classification has beendefined as the particle size of which 1% to3% reports to the cyclone overflow withcoarser particles reporting to the cycloneunderflow. Recent investigations havedefined classification as the particle size ofwhich 50% reports to the overflow and 50%to the underflow, or the so-called D50C point.Figure 3 shows the typical relationshipbetween particle diameter and the percentrecovered to underflow. The portion of thecurve near the 50% recovery level is quitesteep and lends itself readily to determiningan accurate particle diameter. Examinationof the recovery curve near the 97% to 99%recovery level shows that the curve

A general model for hydrocyclone partition curves

Abstract The partition curve is used to quantify the classification in hydrocyclones. It is generally monotonic and asymptotes to a value called the bypass. A `fish-hook' curve occurs sometimes when partition values lower than the bypass are observed. A number of attempts have been made to develop fish-hook partition curve models. These are reviewed and shown to reduce to a general form.
