While it's possible that you could use a coffee grinder to crush your malt, it may not be the best practice. Remember that when crushing your malt, the idea is to keep the husks intact while effectively crushing the kernel. By passing the grains in a coffee grinder, you run the risk of detaching the husk from the kernel.

change from feed size to product size, achieved in grinding, is typically much greater than in crushing. There is significant evidence that blasting does affect crushing and grinding results, and that large savings in cost can accrue (Eloranta, 1995; Paley and Kojovic, 2001). It is reasonable to

Coarse crushing may be required as a pre-milling initial step to reduce a material to a quarter-inch, the largest acceptable mill feed size for most processes. Materials are reduced by fracturing under stress, using compression, shear, or impact forces. Coarse crushing processes can include jaw crushing, roll crushing, and impact crushing.
