[@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!

[@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

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 !!

[@jlucasound]

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

[@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.

[@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.

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.

[@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.

[@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.

[@jondavidmcnabb]

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.

[@ipa31618]

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!

[@michaelovitch]

You should try to adjust the tire pressure,or solve vibrations "issues" with dampening or global mass modification. The mobile jaw is closing while the trailer is boucing up : the rocks are pushed upwards when they should be pinched and crushed : take a look at reduced 0.25 speed. It's killing a lot of efficiency,the rocks are basically escaping upwards.

[@joeridehaeck7677]

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.

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.

I thought last episode it seemed to be running fast. Would it make sense to swap the petrol engine for a petrol generator and go for an electric motor, then you have the torque at whatever RPM you need the jaws to be moving at.

[@chrisallen9154]

Watch the previous video. Donn explains why it is currently running this quickly.

[@timmayer8723]

An electric motor sounds like a worthwhile change. I worked at an iron mine down near the Mexican border many years ago. They used the massive concentric crusher driven by a massive electric motor. It could be stopped by some loads of poorly blasted ore. My job was to sound a warning horn when the ore chunks were way too big and the dump truck driver would stop dumping until the clean up crew could move the big ore chunks around and then resume crushing. Suprisenly it was a very quiet process.

[@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. 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 😊

[@The_JEB]

A conveyor belt you can back over would make this a lot more user friendly

[@MJOG]

Why does a video showing rock getting crushed have so many views? Because we all dream of having one and it’s mesmerizing.

[@dodgeme1986truck]

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

[@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!!

[@sueastside]

This is like watching paint dry, but with rocks. I love it! I bet you will be building a nuclear power plant in a few years to power your homestead.

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

[@faustinpippin9208]

how long does it take to make 1m3 of gravel? Great channel btw.

[@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.

[@jpsimon206]

There is enough vibration that if you built a big hopper on top of the crusher, you could just fill up the hopper even if it was more in front than on top. The vibration would be enough to make it self-feed. Then maybe you could drive slowly while dispensing gravel?

[@morgansword]

I am curious as to the idea of a cone crusher. Would probably be hard to build but they were very good crusher. I look forward to anything that you build Donn. Your so talented as a creative person and could build a rocket if you wanted to. Please keep doing this as I just love your work ethics

[@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.

[@Deckzwabber]

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.

[@andreaboggia]

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