Jaw Crusher In Action - Crushing Concrete, Bricks and Rocks

Crushing concrete, bricks and small rocks in my homemade jaw rock crusher.

[@Jimmy_in_Mexico]

You're messing with us. Didnt you already build the 4X4 UTV

[@Whateverpoopiepants]

Could you just hard face those existing jaws with the same mig wire they use for bulldozers blades ?

[@calholli]

Just a suggestion... You would be a lot better off to take some of your flatter rocks and lay them out in the bottom of these puddles/ holes.. and then bust gravel over the top... So then you're only breaking the biggest pieces with the machine and not having to break every single little piece; so it's a much more efficient operation, and also it will keep the gravel from sinking into the mud so easy over time.

[@elgarajedetk]

I adore your videos and in the next video you could make a receiver for the rock crusher so that you would fill it once or a few times and that's it that way it would be much less work for you

[@myharris]

Need a conveyor belt so you can take the crusher to the rubble dump and crush gravel straight into a tipper trailer. Saves double-handling into the trailer, plus spreading is easier from a tipper trailer (like Andrew Camarata does gravel with his tip truck). Munched that flint no problem - awesome machine!

[@jlucasound]

Taking junk rocks and turning them into clean, solid fill. Genius.

[@desmonde3423]

I think the crusher needs a big hopper so it will self feed thus pushing weight against the jaws to speed up the process

[@mrlithium69]

yea. Right now its manual load 1 single chunk at a time, gravity fed. Maybe you could build some kind of a chute or ramp attachment to push more in.

[@advancednutritioninc908]

Until he gets hardened steel cutter teeth, a hopper will probably overload the crusher - too many contact points which will put way more force onto the moving parts. Once he get the proper hardened cutter / crusher teeth that will probably work!

[@hammeredanvil7377]

I agree. Choke feed is the go

[@Alan_Hans__]

When I saw that you were building a crusher I thought why would anyone want/need to build 1. Now that I have seen it in action I realise that the many cubic metres of rocks and rubble that I have here could easily be processed by 1 of these. Absolutely brilliant work, again.

[@bartonrobinson4266]

Regardless, speedup or normal speed, watching your crusher crush it's stuff is more appealing than watching paint dry any day Donn. Machine looks and works terrific and the end results are less mud tracked in and around, very good thought and build !!

[@quarlow1215]

Bart.... do you miss all the painting on Seeker. Lol. Just give it a year and there will be more to do. Awesome build Donn. I can watch a crusher all day long. Of course that was my job for awhile 🙄

All his opportunity for spiritual growth is had turned to dust now that he can not sit and watch the rocks grow. Watching paint dry is way overrated with the fast drying synthetic paints.

[@CrusherFitter]

A jaw box would help. Keeping the jaw full aids the crushing and stops the material bouncing. Also a lower RPM will be good but you might find adding another flywheel the other side would stop it stalling out.

[@dannmann17]

I think this thing will last for centuries with maintenance, Donn is my favorite youtuber

[@rodneycassidy6037]

Absolutely love the build first off. There seems to be something about the motion of the jaw that's causing it to be ineffective. To short of a stroke or to long or maybe how the lower part of the jaw moves. This looks like it would make a good secondary crusher getting fed consistently sized rock from a larger crusher. Love it man keep em coming.

[@DanKoning777]

BRAVO! This build is a success, and with the fine tuning you've spoken of, it will be everything you expected. *Well done Donn* and God bless.

[@johnvro967]

Hi Donn, That works great, watching the video was hypnotizing, and very fulfilling seeing you enjoying another one of your fantastic creations. Compliments all around !

[@joeridehaeck7677]

U crushed it with this build.

[@7891ph]

Definitely need a jack shaft; making more powder than you probably like. Base layer you're on the right track with the larger sized aggregate; top layer you actually want more concrete powder, the original cross bond's of the concrete will partially reform and really pack in well. Another trick we used on the farm was to rake in some fresh concrete powder with all of the crushed in the top layer, it really tightens up the mix, but is only useful for the finer sized aggregate, like you made in your initial tryout video. The coarse stuff you made in this video is great for the initial layers in potholes, but you need the finer stuff if you want a smoother finish.

[@olddawgdreaming5715]

That was so satisfying to watch. I would still, like to see another crushing video. Different types of country rock, river/glacial cobbles. From soft to hard. If it can crush quartz cobbles it can crush anything. Something to think about: a steal tracked micro bulldozer. 1.5 - 3 ton 20hp v2 gas engine. It would help you build your ranch roads.

Great job mate! You could try hard facing the rebar

[@neillawson4493]

You could probably use a larger hopper to feed the rocks in. Something removable/openable in case of jams...

[@pellejons5920]

Would a "funnel" over the intake work? So you can fill the funnel and do something ells while the machine works. Or stones maybe just jams upp in it. Great construction, nice work

[@msx80]

I think it would! The weight of the rocks would also keep the lower ones from bouncing and speed up the process. It could jam but it vibrates a lot. I think a 30 cm funnel would work great

[@iteerrex8166]

Yes it’d 100% jam up.

[@leen6bt]

@@iteerrex8166 no it wouldn't. "real" jaw crushers also have a chute.

[@jeremysnow8255]

I really like this build and have watched all the build of this you have done an awesome job. I think maybe a small counter balance on the fly wheel might take out the bounce.

So now that you've had a chance to use it a couple of times, are there any changes (other than the gearing) you would have made to the design? In my opinion, that's one of the coolest things you've built!

Excellent 👍👍👍. Thanks for sharing

[@gregfeneis609]

You might experiment with varying the tire pressure or using a solid wheel of some type. As it is now, the entire machine hops up and down countering the moving jaw, but the input chunks hop out slightly before the jaw bites it. I suspect limiting the main body dynamics will let the jaw decimate the input chunks better. To this end, balancing and or reducing the speed may help too. For the average size chunk weight/mass, there may be a slower speed where the hop intensity works to your advantage. Really enjoying this series, though. I'm surprised at how effective it is. And, you get perfect driveway materials, some combo of sand, pebbles and rocks. It should roll out nicely.

[@charlescroney2742]

Great job guy,

[@hermannwiedmann5852]

Der "Schüttelschorsch" funktioniert ja prächtig Klasse Arbeit Cheffe

[@avosauto]

I agree with some comments. A funnel would be cool plus more weight to push down. Also I feel if you put the rebar horizontal it would also push the rocks down. Plus a scoop on the bottom that flares out as wide as the wheel width to spread it out so you don’t have to rake as much. Awesome job!!

[@garymurt9112]

Cone crusher is most generally a second crusher in a series, it's limitations is the difference between the exiting rock is and the size of the entering rock. If the rock entering is the size of a soccer ball ⚽️ then the outgoing rock can only be crushed down to a baseball size. To achieve rock like he is spreading the incoming rock needs to be baseball ⚾️ size otherwise it will not fit in the opening to get crushed. In the big mines the first crusher takes rocks the size of refrigerators and reduces them to half the size, the next reduces them to half again and so on. Initially the start up cost is huge but the tons per hour is extraordinary faster than one crusher trying to reduce huge boulders down to finish product in one go.
