Really enjoyed, your setup looks terrific. Appreciate all the work that you’ve done. There’s a lot of work that goes into producing a diy mill wash setup. Nicely done sir! Peace Prospector Tripp
19:05 I agree with the other guy, use a dab of jetdry, I see you have flower gold floating around. It breaks surface tentation and it lets everything fall out, a drop per 5th bucket into your mill would do the trick.
I admit I was a bit skeptical at first but I love the innovation and the obvious time and love you’ve put into this project. Have you considered a screw classifier from the shaker table tailings with output back to the ball mill inlet?
Spiral clasifier would be ideal for dewatering and bagging up my tailings, not sure I would need to re feed them into the ball mill again though, only a few specks of gold escaping the table now. Losses are the lowest they've ever been, which I'm soooo happy about finally! Still need to reduce my grind size down to 50 mesh though, that will see alot more ore getting sent through the ballmill to be reground.
@@TheGoldmansChannel I’ve seen a few folks (orophilia, MBMM) say that the larger oversize has a tendency to roll off the shaker table and can contain unliberated gold in the matrix. Running the oversize from the screw classifier back to the ball mill will free up more gold that can be better recovered on the table.
There's definitely still gold in the sand that needs to crushed finer to be correctly liberated, but solving that issue in this case is as simple as reducing the output screen size on the ball mill. Remember everything that goes onto that table first has to pass through that screen. It will stay in the crushing system in a continuous loop until it's fine enough to pass through. Still waiting on my 50 mesh screen to arrive, crushing to 35 mesh isn't fine enough, there will definitely still be losses there like you said.
Have you tried painting it with liquid rubber? I recommend Mount Baker Mining and Metals, he sells rubber shaker table mats and he can show you how to smelt sulfides.
Great work young fellow! Are they some trampoline springs I see under the table? You've done a great job on all the electrical side as well. Could be a career in that if you wanted it ;-)
When they're set up correctly, they're bloody awesome. I've used mine for all of my big alluvial clean ups for the last 10+ years without issue and have now started also using it for the hard rock side of things. Love my spiral wheel
Ah, it's season again! G'day! Lovely to see your best friend is even calmer than last year. My boy has been watching me work on my table. I was wondering if you know more about the physics? I assume 30Hz ≈800rpm? The water was pulsing when I watched, I know that is an issue for most (unless one has a huge 2.4x1.4m table). Maybe you‘ll need to put in an open buffer tank uphill with an overflow down to your reservoir. Talking about water: Gardena everywhere. Here we have a winner 😉
He's turning 11 next year, so his supervision skills are improving greatly now, much less harassment to go and play, more relaxing and snoozing 😆. The pulsating water is the next issue to fix on the table because its a big issue. Probably amplified on a smaller table, but still a big issue on this one. Consistency of all forces is essential on a shaker deck. Ill go measure the driver and driven pulley sizes for you next time I'm up at the plant, then I can calculate the speed for you correctly at that running frequency. 👍🏿
They are like their human friend, treat them well and the returns can’t be weighed in gold. Now: I know @Orophilia has been working on portable tables and I warmly recommend you‘d take a look at his very impressive engineering. I‘m looking in to using a metal spreader to ensure calm laminar flow over the table instead of nozzles. Then I recall someone had an empty PVC pipe in the upper feeder basin above their (Miller?) table that did the trick for them. Maybe install a birdbath with a spillway to calm it down before the nozzles? Then I would also want to have a the jerk I can set and less of an abrupt knock on a small table. I have waited for this for months mate, thank you so much for keeping at it whilst others bathed and relaxed. I have a frame for a Polystyrol window and wood and foam and whatnot for the table. Then a big box (with Gardena couplings too 😎) and I have three pumps to select from. It‘ll be my winter project, I want to drive it from a lead acid battery on a boat one day. The physics behind these tables is quite interesting and seeing your table I‘ve also thought to myself „well, that works well for that mesh size and minerals so probably one can also just adjust ones own table to the material one delivers to it. Have a good one! Still on Patreon mate?
@-r-495 Good morning, I was up at the plant yesterday and measured the shaker decks drive equipment for you. The 3 phase motor is 1430rpm The driver pulley is 63mm The driven pulley is 180mm With the frequency set at approx 33hz that should give us around about 300rpm at the table. Thanks for all the tips and info, I appreciate it all! Yes I'm still on Patreon and PayPal, Thegoldmanschannel@gmail.com Is the link for both. Cheers mate!
Is all the extra labour and energy inputs to get the small fine gold really worth it or would you make more by running more volume of material through the sluice with the time you have to work?
You should modify a automatic aquarium fish food feeder so it feeds your spiral with the material. Just need to dial it in. Great “set and forget” way to do other stuff instead of feeding it with a spoon every now and then 😊
I dig your shaper Table Man. I wonder if you could vacuum the gold line off of the table prior to it hitting your concentrates bucket. A small pump driven supper bottle
The super mini shaker table dredge? I like it! I have another solution currently in the works though, going to incorporate the spiral wheel into the system and have it process the 1 and 2 cons as the table is running. Will seperate all the free mill gold into the container and will still catch all the heavy minerals separately also. Should work fantastic.
Just watched your videos mate. Great work. I have a question.... Why do you run a wet chain mill? Is it for dust suppression? I'm in the middle of making a 3 point linkage PTO crusher/mill for behind a compact tractor so I can take my crushing plant to the rocks. My chain mill is fed through the end plate and the exit chute is up high so all the material is circulated until pulverized small enough to fit through the top screen. I was of the understanding dry rocks/dirt pulverize better than wet rocks. However I will have fine mist spray jets in the outlet chute of the chain mill to keep the dust down and wash the chute.
Thanks heaps mate, I appreciate the great feedback. You're very correct in saying dry impact mills typically crush the ore finer. However, the advantages of running it wet are pretty handy. For example, (most importantly) the ore can be fed into the plant wet or dry with a wet mill, so no need to wait for the ore to dry, more consistent wetting of the materiel, more consistent flow through the mill and then onto its following components, reduced noise, and of course, reduced dust. Most of my ore here is damp and has clay attached, so running it wet saves tons of time by not having to heat the ore dry or simply wait for it to dry naturally.
Cool stuff. Are you going to smelt down your #2 cons? The sulfides may contain another 20-50% of your gold take. Edit: Nm, just caught your answer at the end of your vid. Thanks for sharing
You're correct, that's the plan eventually. If local historic mining data is anything to go off, only a small portion of the gold can be recovered as free mill. Heaps more value to be had in the mineral!
Hello friend! Yes, all of that gold was previously being discarded with my old gravity recovery system. Sluices have their place in gold mining, but not on a hard rock crushing plant as I discovered 😁
Water drains from bath tub back into supply dam. Need an easier system to empty the waste sands from the tub though, that's where a spiral dewaterer would be super handy.
The only question is all that work and energy and expense. Are you getting back in the gold? Go or are you making more? Then what you spent . The next suggestion would be run all those tailings. When it's raining, bad weather. So you're producing something in your downtime? Good luck
Sampling programmes rarely turn a profit. It's more of an investment to attain better knowledge on the area of interest. Knowledge is power in the gold game, so every failure is an achievement in the grand scheme of things 😊
Help production or efficiency? Good question Maz. Not in this case though I believe, and not in most other cases either. Shaker decks are usually sized to accommodate the crushing plants output. Having a big table with a small plant would mean you were constantly tweeking the water and deck speed to allow for the lack of material going over it. Best to have a shaker deck suited roughly to your crushing plants needs from what I can tell so far. 😊
@@TheGoldmansChannel Thank you for the response, I was wondering if the increased surface area hence travel area helps in separating the various densities more effectively.
@MAZ501 it's a valid theory without a doubt! But yeah, my opinion on it is similar to a sluice. Better to have it too clear then too full of material. But having it too clear will also have a negative effect beyond a certain point. Gotta find that good balance 😁
Great to see a bit of bush ingenuity there mate and I'm glad that shaker table is working out for you and recovering more gold for you. MBM manufactures a slightly different set-up ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-IiWNTzLLTTc.html and the end of the table is slightly angled with a flow of water separating the gold from the heavier metals and black sand. This is not a new idea and Australian Gold Companies were using it a century ago to recover gold as seen here ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-cqk3VaV32dI.html at 37:50. Had a bit of a laugh at the warning sign inside your electrical box, good luck recovering as much gold as you can with the new set up.
Thanks for sharing Captain! I'm very familial with Jason's tables and equipment. They build some fantastic gear! My table certainly isn't finished and perfect yet, but at the least it's now functioning in an acceptable manner for me to continue with my sampling programs. Many changes will no doubt come as I continue to use it and find ways to improve it. 😁
