Hi everyone, 


I am a CE student and I am doing my graduate thesis. My work seeks to separate a dry solid cement sample into 4 particle sizes ( cut sizes or d50s defined = 5 um , 11 um , 22 um , 45 um ).


For the 5 um d50 stream, i'm choosing to implement a cyclone separator. Currently im looking for classifiers that works with DPCs in sizes 11,22 and 45 um, and in this range cyclones aren't recommended.



I found that dynamic air classifiers are used for this range, but I cannot find a bibliography that details the design of these equipment, I only find an offer of classifiers from industrial companies and i need to design it.

For this purpose im posting this message, looking for your help on a theorical-bibliographic reference for this equipment design.


Thank you,

Do it simple,,,,  German companies are the best for microdust separations.. hereafter you will find one of them, follow  the subject and you will find theoretical papers
