ROCK CRUSHER JAMS UP!

- Just your average rock jam at the jaw crusher, its best when these clear themselves rather than having to stop the machine and un-wedge the rocks. We let it run itself to see if it would shake itself out and it did. YMMV. Thanks for watching
Unjam at 13:55

Thanks for that. That's 15 minutes of my life I'm not getting back. Lol.
Thanks for saving me 15mins :)
Go watch some paint dry! :)
Yes. But it was important. Keep praying until God answers teaches the Bible.

Thank you for this! The entire time I was hoping you would just let it run and see if it would clear itself. And you did. And it did. Now I can die happy. :)
Thank you for this video.
Great job 👏🏼👏🏼👏🏼
We just use an hydraulic hammer monted on an excavator lol. Usually takes 2 mins and it's back up and running.
Yes! I wish we had one the right size, we have a large one that would be overkill for this application.

just take the bucket off and use the quick hitch!
And let the game of rock Tetris begin. At least it’s not an impactor
If you were paying that guy by how many rocks go through that machine, this jam would have been stopped in the first minute!!
There’s always one rebel in the crowd. Lol!
Take a 6 foot piece of 1/4 inch wire rope put a loop on one end and an excavator tooth on the other, lower this wedge between the rock and the jaw and...bang, zoom, problem solved.
I ran a 225 thp crusher in the army back in '69.
hello, we are manufacturer of 【mobile rock crusher】, set 【 price & details】click web: www.fotemining.com/mobile_crusher.html?cuiy bhycll99@gmail.com
I used to run a 42 x 48 jaw crusher in the sullivan mine in the 80`s. the top of the jaw was the pivot and it had a 6 inch travel at the bottom. if this happened we had to put more on top to hold it down or it could jump out of the crusher. We also had an L hook on the crane to turn the rock if it proved stubborn. Blasting was our last option and as small a charge as we could to just get the job done to avoid damage to the steel.
We called the big rocks goonies.And it was generally blamed on the loader operator for not seeing them. We had a cat walk all around the primary jaws and also had an old steel tooth off a loader bucket hooked on a cable that the operator would hang down in and catch the rock enough to break it. Occasionally we'd have to dig them out with the crane. What ever it took to keep stone on the belts.
Amazing 😲😲😲😲
Okay because you stuck with that to the end I subscribed to you. you are awesome.
Nice job 👌
We have one of these only much smaller. Love it. I came here looking for a solution to an even smaller one we have that is a POS and keeps LITERALLY jamming, even with the smallest of loads. Paid a lot of money for it and it doesn't work. You shouldn't have to coddle a rock crusher.
I have 2 vintage crushers from the 20s, a Case 10x20 and Universal 10x30 on a Russell crushing and screening plant. I only crush lime stone, I’ve had stones go in that aren’t to big but by their shape the jaws won’t grab them. I’ll toss in smaller stones around them and it usually will help. I would have done just what you did, let it run, usually it will clear itself. As you probably know, if you shut it down and rock wedges in tight with jaws in the widest open position you will have fun and spend sometime clearing it.👍
Que presio tiene una maquina de esas ?
An old school window weight on a rope is what I use in these situations. Just lower it down between the jammed rock and the crush plate a couple of times and that gets things moving again !!!
back years ago, guys used to weld a loader tooth onto a chain then drop it into the jaw, jaw would pinch it, tooth would fly up like a rocket and break the rock, and i thought those new portable jaws had a jog reverse. lol
@@fivehigh4718 my exact suggestion-tooth cant be larger then jaw opening.
ROCK CRUSHER this needs to be maintained
Joe, some time just make a LONG video of loading the crusher like this when it's working. I could watch that for hours--love watching those rocks get crushed!
I will do that! You want just the jaw crushing action?
@@JoeRockYT Yes. I see quite a bit of YT demand for jaw crusher feed close up and feeder loading action. There's quite a bit of that on YT but they're short clips. I think you could get lots of views! There's something cathartic about watching those huge rocks get crushed down like that.
@@BlackButteMining I will make one! We are getting ready to move the crushers to another quarry, so I will make it once we get them up and going at that location.
@@JoeRockYT Good luck with the move. This guy in Slovenia has some good crusher feed videos - not as good as yours and only a few minutes: ua-cam.com/video/knX2mIhgt2Y/v-deo.html
Yeah me too me too I second that
I just open up the jaws for a minute when that happens to get it to feed through. It can be hard on things to get it to start back but the belts will generally let you know if it’s going to take back off again. That’s why it’s nice to load with an excavator because you can give a little nudge to help start it into the jaws and break up and you can control the flow of material way better. An impact crusher will smoke a jaw crusher on production as long as the material is good and dry but a jaw crusher sucks too if you get into mud. The impact crushers are nice too because you can clearance them tight enough to put out almost entirely agg base with minimal oversize.
Thanks for the positive, constructive comment. You are correct, an excavator definitely gives you more control over the feed.
@@JoeRockYT you’re welcome. It’s clear to see which guys in the comments have or haven’t run a crusher. It’s a normal occurrence for an oversized piece to get hung up here and there and a lot of the time it’s better just to wait until it wears enough off to get a bite and start again. Generally as long as it’s small enough to get down to the jaws it will eventually go through it just depends how long you’re willing to wait until it does. lol the most ideal situation I’ve found is to have an excavator with a thumb and bucket that are narrow enough to fit down into the bottom of the shaker box so you can push or scrape when you need to and have it set up on a pile high enough to see the jaws. With an impactor you have to set the excavator to the side or the back corner of the box of course to keep from getting the windows knocked out but it’s still nice if you can see what’s going on in the box.
@@garymurt9112 you feed a mobile crusher with a rock truck?
No O.H&S in my day; family business had a bigger setup than this with no safety grid over the jaws. We had a large feeder bin( 10 cubic meters +) set up above the main crusher; it was my job/responsibility to make sure anything too big never made it as far as the jaws, I still have the 16lb hammer I used to break these up in the feeder bin.
Don't miss those days but man; they sure built character 😥😥
Build muscles too and sometimes a vocabulary.
Good video. ♡ T.E.N.
And THAT's why a manned feeder was so nice because they could see a big one coming, stop the feeder and let the jaw almost empty out and then chug the big one in there and most of the time the jaw'd bite it 1st thing and down it'd go. Or a shovel shank on a cable and BANG, they'd jump right up out of the jaw but would usually go back down but we'd find a corner to wedge into, just in case. And the old sheep-nosed rock hammer. Kick a little dust in to get it to bite. The new one has the hammer on it. Knock a chunk off it before it falls in.
Story of my life. I run one of these same units for a site and utility company in KY. I feed with track hoe in this instance I could stick my bucket in there pull that piece back out and have it go in a different angle or take a bucket of fines to fill the gaps a lot of times it will bust out but this is always a pain in the ass I feel your pain !
I am curious, would it not be better to use a screening and grading pre-crush separation process to weed out oversized rocks, and that dirt that some of said dirt made it into the crushing section instead of being screened out before it entered? When i was younger there was an attachment made for excavators and loaders which was branded, here in Australia, "Flip Screen". That was a two-in-one scoop and rotate bucket that had a mesh that could be set up for whatever sized grade you wanted out of it. Load un-screened raw material in the front of the bucket, rotate one way to separate the finer grades that fall through from the coarser grade and then move to a different spot and unload by reversing the direction of rotation. Very efficient and highly mobile attachment.
If you were to load the raw blasted material into a screen, you would risk breaking a screen.
That rock crusher is WORN OUT !!!
We used to have a operator with a clock running the vibrating conveyor. 15 seconds on, 10 seconds off, stopped the crusher from getting jammed or the the conveyor from stalling (at a mine, or being brought to the mill from another mine site). Not worth the time to overload
14:04 The big jump in the rocks is when the big stone finally got crushed.
2 things I've noticed in this video here..one why isn't there a portable rock breaker and two why don't I see a dust suppression system on this to keep the dust down?
Why do people worry about dust? If it were not for dust it would not rain. California and Arizona penalize property owners for too much dust, but look how that is working out... Moisture rich air blows over their states, creating a self induced drought. Put some dust in the air and more rain would fall. Every tiny particle that goes up had a chance to come back down with a drop of water, and whatever mineral it carries with it can add to the soil. These states with anti dust regulations are causing the death of the rain makers... Dust clouds
Just keep the feed hopper on and the weight of the stone ontop of the big rock will help the crusher bite it
Always more risk of this when using a wheel loader to fill the hopper. Excavator is far superior for keeping an eye on and regulate whats being fed in. Plus if you have a ripper for the excavator any blockages can be cleared in seconds. I run a Cat 345B and Terex Finlay J-1175 jaw crusher.
Agreed, Should of stopped feed too let jaw clear
I usually take bucket of our 225 and use quick hitch to give rocks a gentle nudge 9 times out orpf ten it clear but I learnt a little trick of an old boy in a qaurry a old digger tooth on a chain let it work its way down a little bit and usually helps clear but our metso jaw crusher has a control box on top we can stop the jaw then reverse it at touch of a button or open it slightly and let it clear as it has a hydraulic ram instead of having to adjust the jaw manually operator her is loosing mega time on production
Wouldn't the absent of material off the conveyor be a clue to Mr. Smoker? Maybe having him sweep the crusher clean of debris & clean off the walks/platforms of rock would give him an incentive to look next time for his lighter AFTER he checks for production issues.
🤣🤣🤣🤣
👍👍👍👍👍👍👍
Man, how long did I set here,listening to that damn noise with the camera focused on nothing? Gooooooodluck!
Cap under a hard hat is instant dismissal on my site
Finally
Now i know how to solve the problem just wait lol.
That might be the answer to a lot of things in life haha
Yeah normally the weight of a build up behind the bridging rock holds it down and stops it bouncing around. It’ll fracture soon after that and if it’s proper stuck take your bucket off and whack it with the hitch. Seems to do the trick.
So does your unit ever throw high and low sensor faults and shut the feeder off and/or jaw ?
Yes. Pretty common with these units imo.
Dam jaws wore out
In this event I just open the jaw setting until the jaw “bites” and then close it back gradually to required material size setting.
After 40 years being in rock plants been there and done that wish I had fifty bucks forever time I unbridged ikrusher
I ran a big 25 ton per hour crusher in the Army. When it got stuck, I climbed into the hopper and and forced some rocks in to give it something to grab onto. Here they had no product for 13 minutes. Looking at it did nothing. Eventually it would grab and clear but that’s lost time.
Big 25 ton?... this looks like a terex XR400S... I may be wrong but this machine should do 25 tons in 15 minutes easily haha....
@@noelweightman9314 Keep in mind, this was in 1963. And the Army, not private industry. So it was probably pretty old by then.
@@rayewen3347 I appreciate your service. That wasn't a real popular time to be in the military, so thank you.
I always pulled guard at the crusher and played with the machines.
Did it not work?
First thing in crusher class in college (mineral process engineering) was don't choke feed a jaw crusher.
Then you've been taught wrong
I hope this question doesn’t seem critical of your operation. Because I certainly don’t mean it to be.
We (typically) feed the crusher with an excavator because we feel like we can control the oversize better that way.
Do you have a lot of hang ups using the loader? I know all the benefits of using a loader. So I’d like to know in your experience what are the drawbacks of using a loader in that role?
You have me rethinking my operation.
If you have to run any amount of distance for material a excavator is use less, that's why you use a loader. Or you need to bring the material close to the crusher
I thumbed it up to for you too
Wedge welded on a ⛓️
Whole lot of shaking going on.
Haha done
The design seems to be more rotational rather than back and forth. The moving plate is wasting energy going up and down.
Why did they not shut down and tilt the rock up? I would never have let it go that long. But, I'm relatively new to crushers and currently run 1950s equipment Haha! I'm actually done for the season here, I wore the rolls down, no welders available, plus getting too cold for my little crusher. Love your videos :)
Hi Marysol, if you shut it down their is a possibility the rocks will wedge themselves into the jaw and be harder to get out, 10 minutes of idling without production is the smarter move then extraction and the possibility of someone getting hurt. If we had the right size pneumatic hammer attachment for an excavator that would be the best tool but unfortunately we don't. Keep in mind every quarry has a slightly different setup, configuration and available equipment, this just happens to be the best solution for us.
Look like small jaw. ... mine is a 1930 New-England 24 x 36 ..and fortunately, i have a small breaker monted on a backhoe to avoid this situation which happen frequentely on a crushing day
@@JoeRockYT Thank you! I'm always learning new things! That is one reason I enjoy your videos. My experience is quite limited. I appreciate your time for the explanation! :)
@@SPman8573 I run a jaw and roller crusher, there would be no way to put anything in where the jaws are except pry bars. We are looking for jaws to take blast rock down to a smaller size, so it's nice to learn all this stuff before one gets thrown at me :)
@@marysoldeeley2218 You tell " too cold for crushing" ...where are you based?
Eh bien vous ne connaissez pas le coup du coin attacher à un câble
Done that a few times but should of put the rock in the left corner of bucket so that's the last one that falls done the throat of the crusher then most likely it would crush
stonner what do i need to do stonner
Take the time to sit and watch the stone jam before entering the grinder. What are you doing this for?
THE POWER THE MACHINE USES IS GOOD FOR A CITY BLOCK. TAKE THE DAM ROCK AWAY. AND START THE MACHINE AGAIN. TRY SOME DYNAMITE.
You sound smart ace frehley
I got I have J45 Open the jaw a little bit it will be fine
Dullest crusher plates i have ever seen.
Camera guy See's the jam up and ain't saying nothing !
ce moulin à pierre a besoin d'entretien
Open the jaws up to see if it will drop in I do it all the time it's the safest way
oui c'est sur maintenant c'est courant de monter un petit brh sur la passerelle deux coups et hop c'est reparti en plus avec d2000 dollars tu as un marteau de bonne qualite j'ai fait du concassage pendant plus de 50 ans et je compte en faire encore et encore
Esse é o pior problema da pedreira onde trabalho pedra agarrada na boca do britador
After the first 30 seconds skip to 15 minutes!
Nice job on the loader operator! So don't sort out the oversized rocks & plug up the crusher so you can stand around for 15 minutes asking "what happened?" That loader operator just cost you how much tonnage? Needs a day off without $$ to think about it! He's hard on production & harder on equipment.
@thecouchtripper hahaha, nice try! Just heard it too many times from other people. N lemme guess, you''ve never dug out a plugged up jaw?
I think it was faster to let it clear itself like it did than to stop everything and try to clear out by hand. Nobody took a risk at getting injured and it only allowed production for a fraction of the day... I don't any part of the line came up short at the end of the day because of it. Crushers usually out pace everything else they feed. Why get worked up over a feed loss that wouldn't be noticed on a ledger?
Throw a big one in so I can make a video of it getting stuck and we can have a good break.
malfunction at the junction. A wider and bigger crusher is needed, or learn how to blast. To the size of the present crusher.
By the way, I'm surprised you're allowed to wear a baseball cap under your hard hat. In Most mines and quarries that's a no no. Just open the jaw a bit and it will probably clear. I did notice you tried chucking a couple of small rocks but you quit too soon. Goodluck
You Have an Appropriate ! Surname ! Mister Third Rock ! From the Sun !! And the Crusher !! Keeps !! Chomp ! Chomp !! CHOMPPING !! AWAY !! FUNNY !! INDEED !! MAN !! GO AND TAKE !! A SMOKO !!
Usually they will clear themselves, just have to get a few pieces in the right place. Need a small backhoe arm with a point to stir the 'pot'. The worst is crushing recycled blacktop with rubber sealant in it, just like chewing bubblegum! These guys really don't know what they are doing. Standing around. Should be trying to feed a little and throwing tossable size rock into hole in the jaw.
Lack of water. There would be no blockage with water.
You’re very wrong
@@Naltddesha Don't argue! Give it a try!
I ground thousands of tons of stones and a little water was always enough for the crusher to run continuously. Good luck.
Too much soil to use water without risking a compaction block... That's a real bitch to clear... Like chiseling a concrete and glass mix made of playdough.... No fun, and you can snap the plates if you don't watch for it and clean it up when it happens. Some material you can use water, but some you don't even want to try
Большой процент холостой работы
finally..14:30
Was für Pfeifen....vom Gucken ändert sich nichts😂😂😂😂
Instead of shaking his head constantly, the miner in the black hard hat needs to figure out a plan to clear the jaw. Jezzzzzz dude. Its not that complicated
Прайс есть
Inexperienced must be son in law
Metso all the way
🧐🤔
Wrong size jaw for the job. Lol
石を砕くのに、時間が長いです😅
発明は良いのですが😅
if this is a common occurance why wouldnt you just blast more or aim to break up the rock more with a cone? makes no sense letting the jaw work itself out of alignment while hoping itll sort itself out.
Usually a big outfit has a hydraulic hammer with the shovel to take care of the big ones so the jaw don't have to.
@@lewiemcneely9143 even still that jaw is running without material just burning itself out of alignment it shouldve been stopped and the problem resolved not just let it run and run and run hoping it'll sort itself out.
@@beaubath2537 I didn't have to -ay for it. The generator was running all the time. Nobody sent me a bill for fuel. The old guy in his late 70's or early 80's that ran the crushing plant we got for the last 25 years would've gotten his hammer and got stuff moving. If they wanted to watch, fine with me. Our guy put it through there by the ton. That was years ago too. Probably 40 years ago. I learned from him. I ran everything but the shovel and the plant. There were no boulders while was on the hammer OR headache ball. From that old plant they now run between 12 and 1400 TONS per hour and make from One Man sized rock to screenings and anything in between, for a price. A 100K TON shot lasts 2 weeks at full tilt.They shoot every other friday at 12. I cleaned up the floor so they could fire back up. Helped clear, grade and set the 1st plant. Don't miss it but miss the workers.
Pure bad luck imo with the rock that blocked it, it just landed the wrong way, it happens, it wasnt too big as it went through the jaws eventually, frustrating none the less. The shovel driver cant always see the big rocks if they're re buried in the pile & not showing as he drives up to the stockpile. He hasnt got x-ray vision
Касипоры!
No no
Time is money!!!
get out the c/4 and some sand bags
I thought that rock crusher was supposed to break up rock this one seems to be out of teeth. All this one is doing is gumming the rocks.
Its not crushing any rock!
We probably need to add more rock!
Must be UNION WORKERS, stand around and do nothing. Sooner or later it will crumble. Sad excuse for men !
Unless you think you could lift a rock as big as your torso...lol... There is no faster way to clear it. Shutting the plant down and moving equipment in to wrestle each clog out of the way that WILL CLEAR ON ITS OWN is a waste of fuel and manpower. Yes it took a while, but startup energy and added fuel for moving equipment, added risk of injury if a piece of equipment snapped while trying to wrestle a rock that size, is way more expensive than letting it rumble for a half hour.... Unless your willing to pay for the downtime and take on the risk of people getting injured moving that stuff and bringing in extra equipment and paying for that as well, what they did was the most economical and risk free choice.
Maybe they're penalized for downtime
Have been watching alot of jaw crushing videos and definitely this machine is the pathetic one..
good big stones, those which are square and straight, should not be destroyed in that machine, but kept for building walls....
It's a good thing they don't get paid to think they both would go broke in a minute .... Not the sharpest tool in the box !!
hello
Those guys are clueless!!!!!!!!!!!!!
What do you suggest? have you EVER worked on crushers?
That’s been jammed up for 15mins now..smh...I would have installed a rock breaker on it and it would have freed up.
No good...
Waste of money time worker no experience
It is useless! This
