While Certus Quartz ore can be crushed into 2 certus quartz dust, Certus Quarts Crystals cannot be crushed directly in the IE crusher

Screenshots:

This was actually an issue in a number of crushers, including the Actually Additions, Extra Utiltiies and Lightning Crushers, and it's been fixed now in 2.4.0: https://www.curseforge.com/minecraft/modpacks/divine-journey-2/files/3464189
