Where can I buy.......

[Jim in Idaho]

I'm building a multi-deck classifier. I need 12" x 12", or slightly larger, stainless screens in #10, #4, and #2 mesh. I'm having a hard time locating a seller. Any help greatly appreciated.

Go look on the Grainger site, they sell sieve cloth that'll work great. Your choice of stainless steel, brass, etc even.

THanks, Kevin...I'll check it out.

Industrial metal is an amazing place to wander around here.

Will it be dry or wet?

I'm going to build it to work either way, Doc. Hope it's not disappointing to you, but I'm not into gold....LOL. Though I do enjoy your videos. I'm currently prospecting for diamonds. I built a Wilfley table this winter, but just for something to do.
Also...a thanks to everybody, but I found what I needed at Graingers....price was good, too. When the builds done, I'll post a video on my Youtube channel....Jim Nelson.

Beat me to it ALewis! Also reminds me of this funny wtf panning moment:

Suit and Briefcase? GAME CHANGERS!

You also might want to build a portable conveyor belt. Once setup, you grease the belt, dump the washed material onto the greased belt and as the materials rotate under, most if not all materials (rocks, gravels, etc.) that are not Diamonds falls off and the Diamonds remain and when the portion of the belt where you placed the material rotates back to the top, if there are any Diamonds, then they will be stuck in the grease and easy to retrieve. This is how they do it for deep water recovery of Diamonds off the African coast. The material is suctioned from the floor of the Ocean to a ship, classified down, then dumped onto the greased conveyor belts and the Diamonds retrieved when they come back over the top.

Be nice if it was that easy. There is MUCH more to a grease belt, or table. And, they are not at all portable.

I understand that it would not be easily done but believe it can be. You have to see some of the setups these old Hillbillies (of which I am one) use around here to run Saw Mills. They take old trucks with beds removed or a flat bed truck with no mud flaps, jack up one side, remove the tire, install a specially made rim to accomodate a drive belt for the Saw blade, attach the belt, adjust the slack out of the belt and they are up and running.

I have a sifter/classifier similar to the one you want to make. It is a 4 tier with aluminum framing for the screens and 4 aluminum legs to attach the sifters to. I have used it to sift tailing piles from old Mica Mines to find Aquamarine and it worked pretty good. It would have worked much better if the NF folks would let us pump water to it to wash everything as it went through the sifters. I also used it at the Crater of Diamonds State Park but had the same problem of not being able to pump water to it. The soil and Kimberlite there is so greasy/oily that it clogs up the 3 smaller screens.

Running a sawmill is child's play compared to getting a grease table working well. The grease has to be right....the water temp has to be right, the flow rate of both water, and gravel has to be right. Not to mention that grease tables don't work well at all with the smaller diamonds.
Water to help classify is great, but like you, I have little water to work with in the area I'm prospecting. On these roto-classifiers, they often use rubber balls to help knock the small material thru the screens. I'm not sure how they agitate them....they may simply start bouncing from the force of the vibration. It's tough doing reverse engineering when the manufacturers don't want you to know how their large-scale stuff operates.
