[QUOTE="Outback, post: 320572, member: 1194"] Hi all , I've made a dry concentrator that can reduce down 25lbs of material to one lb ( 10 kilos to less then 500 grams ) in about a minute on the first pass . What I need to know is the percentage of reduction that equals ? just have a mind block at the moment on the maths :8 Also is that considered a good reduction target ? Been making proto-types since 2013 , trying to get the ultimate quick hand cranked design that can retain all the gold from dust up . This was last years best performer , 7 or 8 turns clockwise then turn anti- clockwise to dump the lights .
