Panzers: I break rocks thread

speed bump said:
Hydrated lime is calcium hydroxide, Portland cement clinker is primarily calcium silicates and aluminates. You only form those Calcium silicates in the presence of a shit load of heat for an extended period of time and then a rapid cooling process to make the chemistry really happy. After you do that you still need to figure out how to grind it up and mix in the 3-5% gypsum at really fine consistency.

You could conceivably build a miniature process: find a lab ball mill, them do an old style batch kiln out of salvage fire brick, and buy a bunch of lab equipment to get it right.

Edited to where you know he stopped reading. Going to be cobbling junk together for a while just to avoid the easy way, and people, mostly people. I don't blame him for the last part.

I thought about asking if he wanted a hand for a weekend a couple of times but I've never had to go to Minnesota because my sister prefers to visit Montana any chance she gets.

Ah neat, so you gotta cook the lime together with the other shit so they get all molecularly marinated together.

You have any idea how terrifying those words are when assembled together? lol

I've thought about making a post on craigslist or something soliciting those crossfit-type wierdos.
"Come run a shovel, for free! Such value compared to paying someone to sledge hammer a tractor tire. Wow, you can even bring your own beers and such!"

ETA: the main downside of getting the mud delivered is that I can't adulterate the pour with field stone and old broken concrete chunks. I really would like to load it down with even more than I currently do, but I get in this odd panic where I gotta load the mixer more than mashing rocks into what's in the forms...

Friends are the most effective way to be a cheap skate ever. Sure sometimes you gotta do something for them but they find you shit and help out when you need a hand.

As far as adulterating your concrete, why? Why would you fuck up the part of your house that if you don't fuck it up will be there for the rest of your life with literally zero maintenance? Do it right and walk away, do expensive shit thats easy to redo later like the kitchen half ass now. Experiment with shitty concrete on stuff like a storage building floor.

mushing rocks and such in there ain't bad for it, it's like a proper rocks and mortar foundation but with rebar and good concrete instead of no rebar and shitty lime mortar made outta screened at most pit-run sand because it was the 1800s and who washed sand back then.

Two different building techniques. Concrete is strong because it has small irregularly shaped aggregates (lots of surface area) with an awesome binder. Old stuff was strong because the mason made the stones interlock and filled the gaps with mortar. Mixing it is a good way to encourage unwanted cracking.

He's not talking about stacked field-stone with mortar to keep the mice out. He's talking about concrete with baseball to football sized chunks of whatever rock was handy in it. Ain't no interlocking when you're dealing with rocks that had a glacier dragged over them thrice before winding up in the bottom of a river.

It's not ideal but plenty of shit that was built that way is well over 100yr at this point.
 
Panz how is the gold collection going with your operation? Getting close to retirement?
 
Been busy busy busy. Never sold so much shit in my life. The concrete guys sold over 3000 yards last week. Block plant is humming like crazy.

I’m trying to get the last of the stone made up for the county landfill. Need another 6000 ton to get them covered. Hopefully put a big dent in that this week.

Got my screen plant setup. Need to screen like 40,000 ton of 1/4” minus sand for the paper mill landfill. I was waiting for my screens to show up. Stupid 2 month lead time. They are a 1/4” stainless flex mat d wire screen. Awesome screens but expensive and have a long lead time. Cost me $5800 for 6 panels enough to do one deck and have one extra.

Got the screen running and it was only producing 120t/hour. Not good enough. So I tore into the gearbox to change the timing. Changed it from 45degrees to 55 degrees and took some weights out. That will give the sand more time on the screen and reduce the amplitude of the shake.

Was doing good until I stripped the timing lock bolt out:mad3:. Had to tear the cover off pull a gear to get the threaded plate replaced. The bolts are welded to the plates do theycannot move. They fall out and your screen box is trashed.

Got it all going and these changes bumped it up to 160-170t a hour:smokin:. Should have went 60 degrees and no plug weights but was afraid of making too big of change.

When I fire it up tomorrow I’ll get a picture of the shit show.

Had to drive to the crusher dealership to pic the parts up. Was drooling over a new cone they had in the yard. 850k doesn’t get you much anymore:homer:.

So the timing of the weights is how they get the forward momentum on the shaker to move the material through?

Yes it’s a pretty ingenious setup. This is a jci box which is a exact copy of a Cedar Rapids which was a copy of the eljay screen. These are some of the most efficient screens you can buy. The triple shaft is the secret.

To adjust the timing. What I mean by that is the angle in which the screen moves when it shakes. A single shaft screen moves in a circle, a twin shaft screen moves in a oval shape and a triple shaft screen moves in a straight ish line.

So most screens are setup to shake at a 45 degree angle. It gives it the best overall performance. When you start doing course or fine material you can make these changes to help improve your productivity.

If you don’t fuck up you don’t even need to take the cover off to make these adjustments. So to change the timing or angle of screen stroke we need to re time the center weight with the two outside impulse gears. You can see on the gear closest to me it has a bolt in the out gear ring with 3 holes to either side of it. Each hole is 5 degrees of change. You can see the center gear I moved it to the second hole putting the motion at a 55degree angle.

This makes the material slow down and gives it more time on the screen to fall through the holes.

I also adjusted the amplitude. With course rock screening you want a big 5/8-3/4 movement. With fine screening you want a small amplitude. To adjust this you either add or subtract the rod plug weights in the bottom holes. It had 2 weights per gear and I dropped it to one. I was afraid of making too big of change and fucking myself.

I’m thinking of moving it to 60 degrees and speeding the screen up to 875rpm vs 810rpm it’s set at now. The motor has a split sheave you can add or subtract shims to speed up or slow down the screen. However I would need to drag the welder out and do some grinding in the box that I’m not too excited about.

This was the first time I dug into this, as most of my screening is at the 3/4-2” size and the 45 degrees and 2 plug weights is optimal.

I was happy with the results. Going from 120 to 160t a hour is huge when you have to make 40,000+ tons of it. Worth the time to do this even after screwing up 3/4 of a day because I stripped that bolt hole:homer:.
 
The screen plant spread. She ain’t much but she sure can screen. Screen is a jci 6’x20’ triple deck screen. I have a 150kw genset that runs this circus. Stacker is 30” x 120’ conveyor. You can get 7000 ton in one cone. She makes a big pile.

This is the screens I use it’s a flex mat knockoff. Works great. The crappy thing is you need to get them made for each screen box so they can put the urethane strips where the bucket bars are. So they are pretty much for that screen box and that deck. The individual wires shake like hell and keep themselves from blinding over. They work awesome. Cool thing is you actually get more life out of them vs a standard wire. Standard wire you just wear off 20 percent of the steel at the bends and the screens fail. This shit you can wear out 75% of the wire before it fails as long as you don’t drop too big of rock on it .



Today it seems I have some over watch going on. :usa:

I think he skipped answering this question on purpose.
If it was going great, he doesn't want us to know he's almost rich enough to quit posting about fixing stuff. And if it's going shitty he doesn't want us to know it should be good, but that one employee suspiciously quit and left for the Bahamas.
 
As to the question I’m staying out of the good spots this year. Haven’t hooked my black sand collectors up yet so I don’t want to run the good sand. With the fuel prices so high I’m hauling sand from across the road to help reduce my production costs.

That and I’m too busy to chase that around at the moment:lmao:.
 
A while ago someone asked about grizzly bars in this thread and since I might be experimenting with opening sizes I figured I would post some pictures of what we built last time.

These sections are 28x76.75" with 1.25" (weird size but thats what the drawing called out) AR500 on top of 1 inch mild bars. As a rough guess we have fed 3-4 million tons across this set and they are still in good shape.

i fabacobbled a mini jaw crusher up, still need to finish setting up the 13 horse to power it. it works ok spinning by hand to make asphalt chunks into millings like bits. ill add pics in a day or so for y’all to laugh at and for suggestions on what to improve. sorry for the hijack.

I don’t get nice material like that to feed my stuff. :flipoff2: I would have that fucker wadded into a solid plate in a few hours :flipoff2:

I am gonna try something close to what you have made this winter to replace my feeder that has a rubber square hole screen in it. Sick of putting in 4K in screens that hardly last a season.

Nice this thread is open to any and all rock crushing. I built a little one also. I’m not sure if I posted a picture in this thread at all. I kinda screwed mine up and put too large of eccentric on it. I should have toned it down a bit.

Post up some pictures!!!
 
i definitely overdid the lobe on eccentric shaft to. ill get some pics tommow.
 
Please. I badly need to make one to run off a tractor pto

Any heavy equipment guys between the age of 18-39 want to make around $400/year taking surveys about heavy equipment shoot me a pm. I have 3 referrals slots to use up. Full disclosure I get $50 for everyone who takes the survey, the person taking the survey also gets $50. More importantly you get put on their list and you’ll get 1 maybe 2 a month to take for anywhere between $50-100 each.

Easy money I do it laying in bed before I fall asleep. Then tease my wife I just made over a $100/hr from my bed. Then proceed to make a low ball offer on some sexual favors only to get shot down:lmao:

Surveys are usually about telematics, parts sourcing, potentially automating heavy equipment ect.
