ROCK CRUSHER JAMS UP!

Dam jaws wore out

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.

Cap under a hard hat is instant dismissal on my site

In this event I just open the jaw setting until the jaw “bites” and then close it back gradually to required material size setting.

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

The design seems to be more rotational rather than back and forth. The moving plate is wasting energy going up and down.

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

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

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.

So does your unit ever throw high and low sensor faults and shut the feeder off and/or jaw ?

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 !

Waste of money time worker no experience

After 40 years being in rock plants been there and done that wish I had fifty bucks forever time I unbridged ikrusher

good big stones, those which are square and straight, should not be destroyed in that machine, but kept for building walls....

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.

malfunction at the junction. A wider and bigger crusher is needed, or learn how to blast. To the size of the present crusher.

Dullest crusher plates i have ever seen.

hello

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 😥😥

Time is money!!!

Throw a big one in so I can make a video of it getting stuck and we can have a good break.

That rock crusher is WORN OUT !!!

🧐🤔

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.

Man, how long did I set here,listening to that damn noise with the camera focused on nothing? Gooooooodluck!

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.

Metso all the way

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

Касипоры!

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

Nice job 👌

Thank you for this video.

No good...

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.

Wrong size jaw for the job. Lol

Took them 13 mins to inspect whats causing the jam. Wow lazy mfers

Should have just pushed it through with a rock braker or small digger bucket

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 thumbed it up to for you too

Okay because you stuck with that to the end I subscribed to you. you are awesome.

I got I have J45 Open the jaw a little bit it will be fine

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 !!

Camera guy See's the jam up and ain't saying nothing !

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. :)

Open the jaws up to see if it will drop in I do it all the time it's the safest way

Take the time to sit and watch the stone jam before entering the grinder. What are you doing this for?

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.👍
