It is generally accepted in the field of powder technology that the most objective quality criterion for the optimization of separation is the Hancock criterion. In this article, use an analytical procedure to show disadvantages of this criterion. I also apply the same analysis to show the objectivity of the entropy criterion for the optimization of separation processes. A simple objective relationship for the optimization of separation processes of pourable materials is derived on the basis of the entropy criterion.
