# Calculation formula for classification efficiency of hydrocyclone

The calculation of the cyclone efficiency is to a certain extent similar to the hydrocyclone calculation The criterion of efficiency is d 50 the diameter of particles trapped with an efficiency of 50 To calculate this value use the following formula d 50 d 50 dd v v where d unit diameter m

### Product Introduction

User d50 The user defines the cut point of the cyclone the d 50 the Efficiency Curve Split Method and the required percentage solids in the under flow from the unit The model then uses the d 50 defined by the user and the selected Efficiency Curve Split Method to calculate the fraction of solids in each size interval reporting to the underflow Krebs Cyclone Model

the classification efficiency It represents a particular particle size reporting 50 to the overflow and 50 to the underflow streams The separation efficiency of hydrocyclones depends on the dimensions of the hydrocyclone and the operational parameters Examples of the operational parameters are flowrates and densities of slurries

### TECHNICAL NOTES 3 Hydraulic Classifiers

The classification action of the hydrocyclone is determined by the net effect of the two competing from the formula for the slow relative motion between a sphere and a Newtonian fluid This is the gives the efficiency of separation at any size and the distribution function is more or less

Improving the classification efficiency of individual hydrocyclones will improve the overall classification efficiency of a hydrocyclone cluster This leads to less variation in the particle size distribution and slurry density in the flotation feed which will in turn improve overall mineral recovery

4 CYCLONE EFFICIENCY The partition or performance curve is the method of representing the cyclone efficiency The curve relates the weight fraction or percentage of each size fraction found in the feed which reports to the underflow coarse material The cut size separation size or d 50 is the mean size fraction for which 50 of its particles in the
