Looking through NEI there is a recipe for turning one Trinium dust into one Refined Trinium dust with the mixer:

One Refined Trinium Dust can then be turned into one Trinium Dust and a Tiny Trinium Dust in the Centrifuge, netting a gain of one tiny:

Centrifuge recipe could be changed to only give the Trinium Dust without the tiny.

Please report the issue properly.
