Hello, I work at a large cultivation site that over time has accumulated a lot of shake...over 20 lbs. It's high quailty nug but not popcorn sized so not what we want to package into OZs, 8ths and grams. What we want to do is grind or sift the nugs into fine, joint quality shake. Are their reliable, automatic commercial grade grinders or sifters on the market made for marijuana?
You could try an electric coffee bean grinder. I don't have any experience with it but I think it's def worth trying
