I now have a sudden embarrassment of riches with respect to eggshells and my normal method of processing seems to be inadequate.

In the past I was dealing with much smaller quantities. I have been trying to process 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 for similar efforts? Thoughts?

I need to come up with a long-term solution for processing as I'm getting roughly 8 cases of 15 dozen shells (1440 eggs) every week and there may be more during busy weeks.

I'll be using them for vermicomposting as well as soil amendments.

Wow... You win the crazy about eggshells award. I have 12 a week and just add them to the compost. I know the calcium isn't available to plants but it will be. Still structure for now. I have watched videos that bake the shells then crushed them with a blender as you do. Crazy that you're overheating your unit. Simply awesome the volume you have. Are you sure all that calcium won't hurt your soil? How about a weed whacker... Just put it in the five gallon bucket and turn it on?

The volume shouldn't hurt the soil. I'm mainly adding it to the vermicomposting areas. It aids the worms in their crops by helping grind what they ingest. Better worms, better castings, better compost, better soil. I was just saving my own but about 5-6 weeks ago started getting them from a local bakery. It's been great...but that poor old nutribullet struggles. I have a lot of crushed in the compost as well as a mess of ground in the worm areas. I also added 30 lbs of eggshell powder to beds, containers, and potting mix a couple of weeks ago.

I think a weed whacker would sling them all over the place. Even with the enclosed nutribullet use, when I open them clouds of powder waft away.

BTW @thommesM,

If you're after eggshells definitely try to find a local bakery of some kind with a sympathetic owner. I did and now can't believe the windfall of eggshells. I've received more in a couple of months than I'd have had in YEARS! It's allowing me to ramp up soil treatments. I am already seeing increases in worms when compared to areas where I haven't added lots of powdered eggshells.
