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!

i watched this build from the beginning. i am thinking that this is one of your best little builds ever. well done man....

This is one project that will let you know how good a welder you actually are... Can anyone say stress testing.. Good video, I was really hoping to see it in more action after the last one. Thanks for the quality entertainment.

I just watched a man halfway around the world crush rock for thirteen minutes. This is why I love KZfaq. Thanks Donn!

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

And now the next project a grader (rake)/roller to go behind the crusher, this way you can put down new stone grade (rake) and roll the hole way all in one go.

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.

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 !!

Never thought I’d have so much fun watching gravel being made 🤷🏽‍♂️, but I did, thank you brother!👍🏽

Твои самоделки, уже на голову выше заводских . Ты, МАСТЕР!!! Привет с Украины

Молодец человек, не ждёт и не уповает на кого то что приедут и сделают ему дорогу, сам берёт и делает потратив колоссальные усилия !!!! Пять лайков сразу !!!!

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

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.

TURNED OUT GREAT! You know it is awesome when we watch rocks being crushed for over 13 minutes! 👍😂

best chanel on yt !

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.

It is beautiful that you built that machine so that you could recycle that old concrete

An example of fine, talented and hard working young man, which nowadays is very rare! Keep on rocking, mate!

Thank you for showing more footage of the crusher. Just awesome!

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.

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.

Комментарий в поддержку видео и канала, а также труда мастера.

This is my new favorite way of recycling👍🏻

Brilliant! I just love the way you can take the crusher to the puddle, instead of having to cart the gravel.

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 !

Watching this videos reminds me how many times I’ve plugged a crusher and had to hammer out the plug. Jaw crushers are less prone to plugging but hammer type are notorious for plugging

Donn, it looks like your rock crusher is a very capable machine. I wish you well on your next project, and look forward to seeing it soon

I love your builds because you put them to work as soon as they are finished, as for rock crushing carbide teeth aside it is all about horsepower and for filling in pot-holes in your road I think that you have it just about right.

That thing works so good, that I enjoyed 10 mins of rocks getting crashed lol. Big congratulations Donn! 🏆 I would like to know how it holds up in the long run, specially the bearings.

What a great build! 2:08 instead, back the crusher to the far side of the fill area when you start. Then, simply roll the quad forward to build the next pile.

Great video Donn, the rock crusher is alive!! Great job and will be a big help help around there. Thanks for sharing with us, Fred. 🙏🏻🙏🏻👍👍👏🏻👏🏻👋👋

I sense another conveyor belt being built

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

Preety good! How about using hard faced welding rod on the jaw faces? It’s designed for high abrasion environments.

Parabéns Donn, tudo que você põe a mão vira ouro...Deus abençoe sempre você

Another Well executed project!! Your craftsmanship and eye for detail on machines is fantastic! Well done!! Liked! Subbed !!

Another productive machine to add to the list ! Well built and should last for years to come. Pretty gooood Donn ! Cheers from Sydney Australia 🇦🇺🦘🐨🇦🇺🇪🇪

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!!

Seriously so satisfying to watch! Awesome job on this build.. think I need to make one of these now.

I was always fascinated by this design. Urs came out great!

Very satisfying to watch, can’t wait for the next episode..

Hell Gia! Pave your own driveway like a boss, and repurpose/recycle at the same time 🍺👍

En verdad que esta maquina que construiste es util para el tratamiento de de los escombro y darle una utilidad como relleno para carretera!!! Felicidades y mil felicitaciones por tu habilidad para construir esta genial maquina!!!

Extremely useful build. Thanks👍

I seem to recall seeing a crusher like yours at a steel works quarry in Wales which used Hadfield steel jaws. 12% Mn but where to get some?

So rewarding to see that face of achievement looking so happy!!! Thankyou for sharing! That is great, now you need to build a mechanised rake to go with it. 😁

AWSOME job as always Donn!!! Makes me wish I had one 😂

I've watched this series with great interest. Absolutely fascinating and you are very skilled. Have you considered adding an angled hopper to speed up loading? Also, how is the rebar holding up? It's surprisingly soft when abraded.

I love hard work…. I could watch it all day!

U crushed it with this build.

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.

I remember your old workshop. It was like an old Medieval dungeon when you were making ATV snow tracks. 👍

just like my 3d printer, i think i could watch this thing operate for days without being bored

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.

Hey Donn, they have hardfacing welding rods and wire. So you could just do that instead of replacing the jaws. It would save you a significant amount of time in fabrication.

It is so relaxing to watch you crush all that rock

Great build! What's next?! Love watching your builds, can't wait for the next one!!!

أجمل شعور لما تكتب كومنت وكل شوية تجيك رسالة تم متابعت الحساب يا اخي تحس انك مميز وتجيك سعادة غريبة😅😂 ابي اعيش الحضة😂

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. Any chance of a few dimensions for those of us who might be keen to try our hand at building our own. Please and thank you 😊

Best ASMR on the tubes!

That is awesome and works so well. You should create a grader to grade sizes of crushed rock for different needs

Very good

You may want to use A.R. series steel for your next set of wear plates. Also if you use 1 set of horizontal crusher teeth placed like louvers down to the last 2 inches (keep that part horizontal) of jaw on the stationary side of the crusher it will help with feeding the rock through and speed up the crushing process the horizontal louvers catch and prevent the material being crushed from climbing the jaws also reducing the wear on the jaw plates

Wow! Nothing larger than half a golf ball can pass through your crusher. Well done, Sir!

Heck yeah I always like watching the stuff u fab up so many good projects

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!

It's amazing how well your rock-crusher works good job!! :)

You are amazing, can't wait to see what's next. 👍

Great job! To make use of your trash like this. And fun for us to watch too. Could you set up your crusher next to your rubble pile and have the gravel fall into the bucket of the skid steer? From there you might tip it into the trailer. Some other comments have mentioned it as well, it seems more economical to transport the gravel in your dumper trailer.

I love this series! How can you keep making better videos I don’t know. I would love to see the use of one of these Chinese small Diesel engines. Do you think you will use the crusher enough to justify this or maybe in another project?

This is really an awesome machine, I hope we get to see more crushing once you change the gearing!

hardfacing mig wire welded on top those rebars, i have used lincoln hard wire on farm implement blades(hrc hardness 60-64)it's tougher than hardox! pricey,but you find other uses for it too. and you can face the rebars again after they wear!

Hello Donn it's working very good beautiful machine you can do the all driveway good job well done

Crushed cement is good for a base, but you're still going to need actual gravel rock for it to last.

hey, will you be adding a big bolt on hopper? itll help force more through as well as not needing to refill it as often.

Don I love your professional approach to the job and the quality of the work you perform. Of course it helps to have access to some very handy machinery and the ability to use it properly. Can you tell me please how much is your eccentric shaft offset? Phil

Uhhh ohhh. I see a compactor build coming up👍👍👍

Not sure why this was so fascinating but here I watched the whole thing

Классно дробит👋👋👋💪💪💪 багги разбираешь для покраски?

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

That thing is seriously cool!.

Just wondering if bringing the crusher to the rocks, crush the rocks on the elevator you use for the logs and then haul it to the places you need the crushed rock. Only have to lift the rocks once then. Just a thought . Very nice job in the build. Of course your builds are always great to watch.

That is awesome. Would love to build one on a little bigger scale. Better get the rest of my projects done first. Nice job

Great job as usual! It is always very satisfying to see the machine you have just made works as planned and do the job it is built for! You're great, dude! I'm very impressed by your patience and adamant motivation to actually finish all those amazing projects in such short terms!

Thats awesome! I want one now...

I wonder if welding ribs on plates for build up then weld a layer of hard surfaceing weld curious how that would hold up or run beads of hard surfaceing on top of the rebar. Im in the process of building a jaw crusher and was contemplating how to make the jaws more durable. I have tons of rocks 8 inch and under but could use the gravel instead for yard. That sure is a nice crusher you built good job 👍👍👍 Apparently if i would have read the comments first i would have seen that other people had the same idea of hard surfaceing lol🤦‍♂️🤦‍♂️

Should build a conveyor that leads from the crusher to another trailer. That way you can crush tons

Dang that’s nice. Way to get it done!!!

Best ASMR video I ever seen

it works very well!!!! An option may be eliminate the bouncing, with a weight on the big wheel.. or not?

Great job!

Donn You Rock ! :D

There is welding wire that self hardens when u lay a bead. Dunno if u familiar with it. Could maybe weld some lines on the jaws.

Looks like the crusher is working very well. You are quite the desinger sir. As allways be safe. Peace.🌻

Hardox would be the best bet for the crusher bars. I use it on buckets and my dump boxes are made from this.

Excellent 👍👍👍. Thanks for sharing

Wondered why you went with rebar. Figured you were planning on keeping with the recycling idea and any old rebar recovered would be welded on when these wear out.

Dobra robota👍👍 Przydatna maszyna!!!
