In the past I was dealing with much smaller quantities. I have been trying to do it the same but I have shells stacking up. I'd like to make eggshell powder (or even fine sand) but on a larger scale. My little nutribullet can only do so much before it overheats and quits. Then it takes hours to cool down. I now have probably three 5-gallon buckets of crushed with more shells coming this week. Has anyone used a larger system? Thoughts?
