I am looking for a powerful blender/chopper/grinder to turn up to 1 pound of crystal sugar into fine powder. Only sugar will be used, I cannot add starch, flour, water, oil or anything else. I have tried a regular kitchen blender. It works somewhat, but I am hoping for something that can work better. It is for a research project, not for food, but I thought people here may have some good suggestions. Thank you in advance.
