Here is my charcoal (biochar) crusher made from a meat grinder and a low rpm gear motor. Works pretty well, and doesn't jam up much if you use a plate with larger holes and feed it slowly. www.democratek....
I have a idea for a modification to your grinder. Find a larger funnel, then mark where it will set in a hole. Then cutout the hole put the funnel in so that it will set just right. Cut the small end off, place your container with linear under it.
Thanks. Recently saw an article on biochar in Living the Country Life (Spring 2013) --- hadn't heard of it before. I wonder if it would capture nitrogen if put under my ox's manure pile, which happens to be close to my well --- and does it give up what it captures for use by plants?
Well 4 years delay, but yes most definitely put this into your ox's manure pile. Test's in Germany on using a daily applied mix of biochar and wood chip as bedding for the overwintering of cows, dramatically slows down the degradation of the manure, retaining nitrogen and cutting ammonia gas emissions in a huge way. Then take it all out after the winter and put in a big long line and cover with tarpaulins for roughly 7 weeks, after that you will have the best compost money can buy.
