We ran 2 Lippmann HSI's on the last portable plant I worked, in a closed circuit, being fed by ElJay screen decks. Along with a Lippmann 30x42 jaw. I do not miss having to hand dig one clean after a curtain liner drops free, and grenades the internals.
We could avg. right at 280 TPH the way we were set up here.
Should be a cool project. I know a couple have already been done before yours. I'll have to do some bloodhound work, and track some vids down for you. If you need any blueprints or schematics, shout out, I still have some contacts I could call in for you.
