[QUOTE="bend, post: 551108, member: 4811"] Worth considering passing the oversize back through the impact mill? This is the one you're building yeah? looks reasonably large. I use the concrete mixer because my impact mill is one of those little angle grinder ones, takes bloody forever to do a bucket or two. the mixer takes a while too, but you load a bucket of stone and some balls, turn it on and come back later. Petrol tanks are similar, the caustic acid is to remove varnish deposits, and the boiling process should flush it too. you'd have to force the steam through and ensure no air pockets of vapourised gas remain.
