Thanks all for your kind words.
The hopper has a gate that would most likely completely stop the flow if it happened to stop in the right place but I think the idea is to start everything rattling about and then drop the dirt in. I've not seen the guys about here starting off but to stop they wait until the hopper is empty and that doesn't take very long. This machine should keep the loader running full time but I'll have to scrape the stockpiles first or it'll run empty between loads.
There's no way to empty the hopper without feeding it over the riffles.
I've spoken to a few guys about detecting the heavy gravel that the dryblower rejects. The problem is the rusty rubbish, it ends up in that gravel that falls off the classifier. There could very well be gold rejected especially specimens and gold stuck in the clay but all have told me that it's not worth their time to do the heavy piles. They get more gold processing fresh dirt but who knows we might end up with a wet plant in the future if it looks like we're losing too much.
No they don't get dumped away, they just pile up against the side (yet to be fitted) and get scrapped away with the loader. If the ground is not to contaminated with rusty steel it would be a simple job to drag the gravel out flat and detect.
Keep in mind I don't know this game yet so anything can happen
With a conver belt in dirty conditions,
The drive roller needs a bit of a " Buldge " in the middle to make it track.
Say, Cut and roll a bit of 1/4 flat and then roll and weld in the middle.
You also have to consider that a bit of dirt/rocks are going to get between the roller and belt.
This will cause it too track all over the place.
The buldge stops this from happening.
I have seen this done on grain converers for that very reason.
Bloody nice piece of kit there Moneybox. At least if the diff lets go, You can salvage another one from, some where. LOL
Corner Horton's have them on special every where. :Y: :Y:

Moneybox said:We've got to the point where we'll soon be out in the field doing some trials with the dryblower. It didn't go totally as planned. When I first started the motor yesterday morning the drive belt slipped on the diff pulley. Did somebody mention that, Tathradj perhaps :8
I just leaned on the adjuster a little and set the conveyor belt going. Within a minute or so the conveyor belt had drifted to one side, I expected it might but it was too quick for me to get a spanner onto the adjuster.
That just brought about another problem. The Subaru Suretrack diff started to slip.

I already had the diff apart but couldn't find my way inside to weld the internal gears.
https://www.prospectingaustralia.com/forum/img/member-images/3960/1614264123_diff2.jpg
I ended up having to remove the diff again this morning to dismantle it again.

I still couldn't get inside because these diffs are bulletproof. They sell secondhand in the US for USD$400 or more.
https://www.prospectingaustralia.com/forum/img/member-images/3960/1614264501_diff4.jpg
I felt bad cutting up a perfectly good diff but I did weld it up again
Next I added another idler to the drive belt to get a better wrap around the diff drive. Then it was just a case of adjusting the conveyor belt to stop it working off the side.

The end rollers are from an old 200mm diameter oxy bottle. I considered trying to machine it slightly domed in the middle but I'm not the best machinist and my lathe is not the best.
I'll see how it goes but I'd really like to make a light weight end roller to reduce the weight suspended in the air. These bottles are formed by spin casting and bottom end of the bottle is about 25mm thick.

True, Rollers are hollow to keep the weight down. about 6 " wide would do it.
Grind the welds down smooth shamfering them.
Spin rolling is incredible to watch isn't it.
With multi rib belts, If you look at the pulleys esp the crank pulley,
The outer part of the multi V has wide shoulders on the out side.
The belt sits into the pulley.
The shoulders are there to make the belt track. This is
why also some of the other that are under load have the same thing.
Idler pulleys that track the flat back of a V belt have a slight dome to them.
That is why the belts won't come off them.
The belt is held in place.
A pulley without any tracking shoulders will have the belt moving
when it goes under load.
Make a pair of round disks then lathe a shamfer on the inner edges.
A sealed bearing with the plates all bolted together should be ample.

Mrs M is celebrating.... It's gone
After unsuccessfully trying to move it with Zimba, Tonka came to play.
It was too hot to go out but I was all set to go when our friend Jason dropped in later on. He's 6'4" and a handy guy to have around.
I towed Goldilocks with the little truck while Jason followed up driving Tonka.
We only had a half kilometer out to our nearest lease so we were soon ready to test.
It was instant success although there was a bit much feed going over the riffles.
If making dust is what it's all about then we did it :lol:
However it didn't last for more than a minute or two before it didn't look so good
With the first half bucket of dirt on the classifier the feed came to a grinding halt. It refused to empty so Jason drew the short straw
That little pile of dirt is all that made it through before both classifiers blocked up.
Never mind we had dirt in the riffles so we thought it worth testing the sluice. I quickly added that little rubber flap that somebody here recommended and it really worked well.
This was enough to put a smile on our dial, who'd have expected this from about a wheelbarrow of dirt?
Tonight Jason had a brain wave. Perhaps we should have put it on the ground. I think he's right. It started feeding the dirt straight away but as soon as the classifier was loaded the frame that was sitting on pneumatic tyres did all the shaking and the classifier stayed still.
Let's see what tomorrow brings
:money:
Fantastic for you to see colour in the pan, bodes well for you. Just reward for all your labours. :Y:

Just before 6am where he is given MB'd age I'd say give it a few hours before work starts then sorting out the skaker issue before any more shiny dirt settles for recovery. Gotta say the first pan is bloody excellent
erfect: well done MB :clap: :clap: :beer:

Ok guys, let me breathe a bit. Mrs M has been filling the whiteboard with jobs, more jobs, and more urgent jobs ever since this project started. She pointed out yesterday where a piece of poly pipe had degraded enough to act as a longitudinal sprinkler. The water failed to make to the end and the new banana tree that looked to be thriving is now a brown wilted mess. I guess some things can't wait.....
Excellent work MB.

Morning MB,
It works, that's is the priority, few tweaks and all we viewers will be watching you reap the rewards.
Now a new bit of poly pipe for the banana should only take half hour so we can expect to see the next cloud of dust at smoko?
***When you are up and running, have an unfinished project here you maybe interested in for a next summer project to keep you out of mischief and from under Mrs MB feet. FREE ***

Flip them side ways, Lock Down then wind them to ground level.
If heavy duty enough, Can use them to level out with.

Better than a hand jack. LOL
I should have known better to comment on that one. :8
LOL at the tyres absorbing the vibrations. :sunny:
Marvelous what can be deciphered around a few beers and a feed.
And, If that is what you have recovered out of that small amount,
You going to be very dusty for a long time.erfect: erfect: erfect:
Well Done Phill and Sandra, I takes me hat off to you both. :Y: :Y:
