limpalot said:Expanded mesh seems to work well, long as you have a mat under it that it can pull down into to stop water getting under, thus pull material through too. I split my mats into 2 so I can check where the gold is falling, all at top or some at back, most should fall in first 12".
Matting under expanded is OK in bankers which rely on vortex catch zones only. The "Walbanker" is designed on a two fold principal where vortex catch zones are created in the "Crate" section ( which has either miners moss or woven matting underneath). The expanded in front has "NO" matting of any kind under it and relys on the principal of Displacement only.
Current flow is regulated so a bed of heavies holds up in this section, trapping the gold underneath this bed. Lights will be displaced first, then slowly the heavies. Gold, other than a small amount of flour gold, will not get displaced and build up in front of the first "vertical" riffle, which is the "C" channel holding down the crate section. This "flour gold" will get trapped in the vortex zones of the crate section.
