[USCC] Finished Compost Grinding

[Richard Fortune]

We have an Envirocycle compost bin that we've been putting in our kitchen fruit & vegetable scraps, egg shells and coffee grounds. Well, it's full and finished decomposing, but it's dry and kinda chunky and needs to be broken up before putting in the garden. I used an old Krups blade-type coffee grinder and was able to (tediously) finely grind up about half a buckets worth before the unit gave out.

Are there more appropriate electric-powered devices out there to handle this task???  If so, please name your favorites.

Thanks,
       Richard
