Elutriation segregation

Related Calculations. This method can be used for determining separation effectiveness for classifying screens, elutriators, cyclones, or hydroclones in which a known feed of a known crystal size distribution is segregated into a fine and a coarse fraction. If a cut size cannot be predetermined, assume one at a time and complete the described effectiveness analysis. The assumed cut size that gives the largest effectiveness is the cut size that best describes the separation device. 

Whilst the powder motions of projection, elutriation and percolation have been singled out as being especially prone to segregation, it must be emphasized that any powder motion potentially gives the opportunity for preferential mobility and segregation.
