Rp4 shaker table

[IDAu]

Anyone have experience with this table for processing hard rock? One site says 100 pounds an hour, another said 500.

I have one I can grab for $2000. It’s just me and maybe a buddy working the mine. If I could mine and process a ton every week or two (working 40 hours a week) I’d probably be happy. A $10k+ MBMM table is just too far out of reach right now. Does this sound like a good table to snag, or will I likely become frustrated and wish I waited for something better?

Will likely pair with a 14” KandM crusher.

Thanks.

I'm not familiar with it but, from what I read about it, it may not be appropriate for your usage as you described, since it sounds like the main intended feed is of placer concentrate. It would probably work fine but maybe you could save time and effort if you were to, first, concentrate your milled ore then feed(?).
Good luck.

I have had both. With my current setup I can run 150-200 lbs and hour max. This is hard rock crushed to 30 mesh quartz gaunge. Other ore I run is andesite running at least 1% pyrite and I have to run that slower or I lose alot and have to rerun. It's a great test mill table or clean up but not production considering I'd have to run 10 hours to get 1 ton. It's tricky getting a cleanish number 1 without sending some gold to the number 2. If you're going for a ton a week you'll be happy. I would like to run a ton or so a day so for me it's limiting.

Hey thanks but I already got a better table for even cheaper.

It’s funny people keep giving me numbers and saying it’s not for production, but the numbers sound good to me. Same with dredging. “A 4” isn’t for production.”

I don’t know how much one just guy can do anyway. If I got through a ton a week I’d be thrilled. Even at a half once per ton that’s a livable wage.

I’m stoked I was able to break in and get set up for so little due to some nice people trying to help out a new guy.

Right on looks like a well made little table! Great you got help too. Let us know how it works for ya.

Pulling my hair out. Over six hours today trying to get it to work. I knew they’re not easy to tune, but holy hell. I’ve tried every combination of variables at this point, and this was the closest I got.

To help speed it up try running a few tons over a sluice box then run the con's over your table.

I was told I would have to tune it for my specific material so that doesn't help much.

I'm going to have to get him over to help because I'm on hour ten and worse than when I started.

How about tuning for black sands even if there is some loss?
Just re run to help catch the losses of the first pass.

I don't have any black sand concentrates.


I switched to some of my crushed hard rock I know has black sand and little to no gold. I can't correlate one single damn input to any change in the table. I have

Horizontal slope
Vertical slope
Spring tension
Bump stop
Power input
Water flow

I've painstakingly changed only one at a little time in every combination I can think of. The only change in material I see is when I do huge changes in multiple things. If I do that and it's better than it was before, I change a little in each direction on one input from there. And it goes to hell leaving me worse off, and when I undo the single minor change I just made it doesn't go back to where it was.

I'm stumped, and extremely irritated.

Try adjusting just the slope and water flow and see if that helps and keeping the rest the same. Then start to adjust the horizontal slope for a bigger spread out of fine to course type of material fan to help pull off the different sizes and or shapes. Perhaps you need a fair amount of water just to wash off the unwanted materials on the first pass? Just get your hand scraper out to scrape a sample anywhere on or off the table you want to test in a finish pan. Your pan is a tuning tool to help for a given set up.

Some of the gold will be next to iron. Sluicing different rock material in the dump or mine floor will lead to more iron in at least some of the rock. Then run the sluice cons over the table and tune for a screened size, shape and type of materials. Changing the size, shape and type will have a different set up as a general rule.

I think I found the problem.... Anchors my buddy put in are moving up in down in the concrete.

Yep that is a problem to fix.

 

[JohnWhite]

I don’t know much about this sort of things…But I have heard some good things about this one but it has gotten pretty expensive…But with some of the ore I’ve come across its price is reasonable…Although I’m over that hill and I’m now retired…🤔😱😆😂🤣✌️⛄️

How thick is your concrete and is it steel reinforced?
What is the weight of the table and size of the motor?

Garage slab. Not sure, but from what I read 4" is the minimum thickness allowed.

Heavy. Two people can move it, but barely.

That is on the thin side. The bolt will have to go all the way through to take advantage of the 4" mass. of concrete slab. The expanding end bolts will likely move or pull out if just 2 - 3" in.
If you can set up a tool / garden shed with steal anchors going down 3' - 5' into the ground below the floor will give a lot more mass to shake with.

I cannot do that. We are going to try all thread and epoxy in new holes.

This is annoying because I’m probably going to move all of this up to the mine in the spring. I just wanted to get familiar with it and have it running here so I’m not going through all this once it’s Mining season.

All thread will eventually break ! Better to get the right bolt and not have to worry about the vibration breaking the all thread. BUT it is your choice ! Good luck
