Beach High Banker, Sweep Jig, Whippet Dry Washer, Lobo ST, 1/2 width 2 tray Gold Cube, numerous pans, rocker box, and home made fluid bed and stream sluices.
A hopper with an adjustable gate that spans the sluice and a vibrator (to minimize plugups) comes to mind (fill the hopper with the gate closed then slowly open until you see an acceptable feed rate). Probably best to preclassify the feed.
