[QUOTE="Mike Marsupial, post: 389706, member: 11868"] Does anyone have experience with these? They look very effective, but pretty expensive. [url]https://www.ebay.com.au/itm/Centrifugal-gold-concentrator-mining-PCB-Electronic-Waste-CCFB110-FlexiCone/273065576728?hash=item3f93fa0918:g:PWoAAOSwa-dWhaoY[/url] I reckon a good 30% of what I run through my sieve set-up just runs back out into the river and down to the ocean. It's very fine. But the set-up does a great job of washing out sludge. Problem is that the fine stuff is kinda suspended in the sludge. Bigger stuff is OK, no problem. I finished a Miller table this arvo, so tomorrow I'll give it its first run over its glass bed. I'd like to compare what it does with what a blue bowl can do (and that's a dead easy build), so after testing the Miller table, I'll go and get a big dish (already have a fine collection of funnels) and make a blue bowl too. One question about the blue bowl; Where should the water inlet be pointed, midway up the side? Top? Bottom? Cheers :-) [/QUOTE]
