- Опубликовано: 15 июл 2021
- Fabricating a jaw rock crusher from scratch. Making the moving jaw of the crusher with replaceable jaw wear plate. Cutting parts on the homemade CNC plasma table and welding more and more steel and making this project really heavy. :)
What is a jaw rock crusher - a crusher that has jaws and crushes rocks, concrete, bricks etc. and turns it into gravel.

When I opened RUclips, just now, I saw Donn. I'm right there! Number one choice!! All 400 of my other subs can wait. :-) You are a Master, Donn! (NO! Not "Mastodon"! Those are Dinosaurs!) ;-)
Looks like an overhead crane needs to be added to the build list.
I continue to learn from your videos, and appreciate how you add comments as to why you do certain steps. Very informative, and I am using this as I learn to weld.
This looks like a sign that changes are coming for the barn/shop. I can see the writing in the welding smoke. 😉
Many square meters, no? Only Donn will tell. Ahem, Only time will tell.
ПАРЕНЬ Я В ШОКЕ ОТ ТВОИХ РАБОТ И ОТ ТВОЕГО ТЕРПЕНИЯ 👍👍👍👍
Thank you Donn! Greetings from Poland!
I love when u say ' LiKe a gLoVe'. Ace ventura is a mean movie lmao
Absolutely THE greatest. Keep it Up.
Cheers from Sweden 👍👍
By the way lol I think you did an awesome job on it ! And alot of your other projects. Keep it up! 👍👍👍!!!!

Looking good Donn, it’s coming right along. Thanks for sharing with us, Fred.🙏🏻🙏🏻👍👍👏🏻👏🏻👋👋
I work in mining specifically on crushers, conical, scroll, gyro and jaw, I'd like to suggest protecting the wedge feet with some form of sacrificial wear guards.
Also I would suggest either countersinking or armouring the protruding securing bolt heads on the wear plate and wedge, or you may have a nightmare removing them in the future as material wears the bolt heads.
By nightmare you mean 2 seconds with a torch
@@MustObeyTheRules depends on what and where your cutting, ever seen a belt go up?
Not mention do you want bolts to let go from wear whilst in use?
Just for your own knowledge Donny it's either pretty good or it's great and I believe it was great. haha And I only say this because you are a very intelligent guy.
This is super awesome. Looks really good. Its going to be a beast that is for sure.
Three threads protruding out past the nut is a manufacturing standard in the aviation industry.
Amazing welding with a coating of talent well worth watching as always
There are two RUclips channels That I look forward to new videos coming out.
Donn DIY
And ColinFurze
Yeah Colin tunnel project is awesome. If you like Donn then try made in poland they are great as well. Much of the same kind of videos where they make things they need or want. They just finished up their making a better room in their barn/shed. They even made a tool to adjust a cabinet that was not level and weight a lot. They do lots of cool stuff.
You need to see "My Mechanics". Not a weekly but the quality will make you drool. Small antique restorations. Donn builds heavy equipment from his brain.
One thing I can recommend, as a welder, always cut your bevels before you assemble. You already know where you're going to need them. Also, don't use a cutting for grinding your grooves, use a combo disc. They are just a little thicker and can take the lateral pressures a little better.
I wish I was half as smart and talented as this chap! It seems like he makes nearly everything himself, from the many projects he designs, to the tools to make them! And we rarely see him mess up, get injured, or storm off mad and frustrated from an issue. Are many cuss word spoken off camera? lol There are in my garage!
Instead of welding the nuts to the moving part I would weld the bold to the changable plate. So when the screw gets damaged during operation you still get the plate off.
But having studs welded to a banana shaped plate makes it rather difficult to get the plate off.
Forget about trying to put it back on.
Each way has its advantage but it's easy to weld a fresh nut onto a damaged bolt head, not so easy to bend a half inch plate straight enough to slide welded studs off
You are entirely correct about the bolts and where they should be. There is going to be a problem when he tries to replace the grinding plate because all the bolt heads will be worn and very hard if not impossible to remove. A better way would be to have the bolts come through from the back and drill and tap the grinding plate to accept them. When the plate is worn out the bolts can still be removed.
@@oh8wingman or a quick pass with a cutting torch to cut the bolt heads off bolts are no longer under clamping pressure and will come out fairly easily
He can also just weld a bar on the bolt head to remove the bolt if He ever needs to
You’re forgetting that these are replaceable wear plates. When the bolts need to come out the plate is being replaced so a torch or plasma cutter will work quite nicely to remove worn out bolt heads.
You’re overthinking it or not thinking it as far as Donn has.
This video has a crushing grip! Awesome build! Enjoyed 👍👍
Loved seeing you take the time and effort to cut bolts short even though 'no one' will see them. It comforts me that i'm not the only one taking unnecessary steps like that 😁 greetings from the Netherlands, Mark
Hi Donn,
Great work as always, your MIG-welder got
a workout.
Can't say it enough times, "you are awesome !"
Thanks for the video.
Why would anyone give this man the thumbs down ?
Your Ace Ventura impression was dam good!!!
Fantastic project amazing skills.
You do excellent work, Donn.
Like A Glove!!!!!!
Out of this world Craftsman!!!!!
😁💪🤙
Awesome 👍👍👍Thanks for sharing
Fits like a glove!!
It's looking good Donn!
Great work, however.. I wouldn’t weld the nuts on the underside, when the bolt heads wear off you may not be able to remove the bolt without welding a nut to the worn off bolt head..
I don’t know how that thing is so posed to work but All I need to know is who is building it. !!!! If Donn has had his hands on it you can bet it will do what it is so posed to do.
Looking good Donn! Really cool project!👍🏻 MN USA.
Very professional !
Tks,,Donn Diy,,,all ways liked your tutorials videos,,,good job,,I hope one day learn from you
I've been side loading grinders all my life and I've never lost two eyes.
I see....Hmm..
Plenty others have, Google grinder injuries, saw a guy lose a foot when a disc shattered and a piece flew off and amputated his foot at the ankle.
Only one eye right?.... Haha
Regardless of your personal luck, always good to stack the odds in your favour. Wear the Ppe. Be smart. Get the job done and go home uninjured
Every time I start watching a new series I think: what am I gonna watch after I watch the last one left on your channel?
I may have to start at the beginning again, and look for the things I missed the first time.
Nothing better than a nice groove :)
Love all of it Donn! I'm subscribed from Iowa
This is just the way I would have made it… if I wasn’t busy watching a screen. 😁
Nice work!
Why are you building this contraption? Your fabrication skills are amazing!!! I hope you are going gold mining and will use this machine to crush rock into smaller rocks to eventually run through a sluice. You’re building a work of art here!! What nice welds and beautiful fabrication.
This is what RUclips was originally created for - people not necessarily academic experts, doing their best with what they have then sharing it with any who care to look in. Well done, Mr Donn. Your videos are not spoiled by you assuming theatrical poses and making silly faces. :-)
There was one "Like a glove!" silly face though. 🤪😀
Thank you from Algéria, عمل جيد
Amazing work sir
Looking shweet!
Really the biggest and strongest nutcracker on YT ; ))
I haven't got the faintest idea of what this contraption will look like when it's finished, nor how it will work, but it is already fascinating!
It’s a jaw crusher 🤦♂️
Amazing brother 👌
0:57 was just thinking, wow you got the plasma cutter very well dialed in!
He is so good, isn't he?
Красавчег👍👍👍👍👍
Hello Donn is coming along very good well done my friend
New saw blade ! Yay !
Looking good....
Coming along nicely! We shared this video on our homemade tools forum this week :)
Thanks!
16:58 Tears of joy or just plain old sweat? 😁
"Like A Glove!" 😁😆😂🤣😎 made our day!!!! I've seen less engineering in a excavator bucket, thinking it will be a rock/concrete eating monster!
Loving this ,super skills.. for the jaws maybe find the rack from something with a rack and pinion gear.. automatic roller gates would have it , could make some teethy jaw plates with bits of the rack
Cool project 👍🍻💪
Looking good
Add a Bash of Dash and the Rock Crusher will Perform with Spirit and Passion. Looking good Donn, good crushing ahead, don't forget to keep feet and hands clear when working it !!
Cant wait to see it working
Молодец всё с огоньком и с душой! 👍👍👍👍👍🤝
That is one "groovy" grind. @8:36. Like the "infinity" symbol. Far out, Man! Weld Away!! ;-)
Nice work
Ya iba viendo que sería un molino , eres todo YA NO SE QUE DECIR, si maestro artista. Pero vaya trabajos de calidad que hacés
You must have ALOT of bricks! Going to make gravel? Looking forward to the next installment. Looks great 👍
You do great work . Is this the type of work that you do at your regular job . i love the pre- weld beveling you do . From USA Ohio retired weld Inspector . Thanks for sharing .
Hey Don could you possibly build a winch system on your shed roof for lifting heavy items and some of your projects? Just a thought
Let’s go!
The build is amazing but you should think the wearplate mounting through again. The boltheads are going to get super mauled by the bricks making the plate really hard to get off. The mounting hardware should be welded to the wearplate, not the other way around. Keep on doing what you're doing!
Thanks donn. I got stuck at the toggle plate. Following keenly from Kenya
Excellent work as always !! Gonna be very heavy duty........is there any other......nope not on Donn's channel .....I wouldn't want it any other way !! 👍👍👍very nice !!
Cheers man!
Are you sure that's a rock crusher and not a new shroud for Chernobyl!
Crikey chief!
Fantastic
Yes!
GROOVY.
Gantry crane for next build.
Like a glove. 👍 nice touch. Lol
I do the same thing.. lol.
Using the old cut off wheels from my chop saw. I ground a washer down to size to fit inside the oversized center hole; It works great... free discs
Yes. Otherwise they would go to waste.
väga lahe tehnika, kas kõik omal hangitud, või toimetad kui reklaam😁
Selline on unistuste garaaz😉
Edu.
Excelente,,👏🏽👏🏽👏🏽👏🏽👏🏽👏🏽👍🏽👍🏽👍🏽
man this looks overkill, but i guess you could crush the empire state building in a week with that
24.5 C = 76 F,,,,,,, I weld in 86 F+ inside with 70% humidity, but sense your the boss and chief engineer you can have AC put in. When one is doing lots of grooving one should have a carbon arc gouger onboard, also great for taking things apart when and if you ever weld something together wrong..........
That thing is gonna weigh a half a ton when done!
Мастер за работой
I use my plasma to rip flat bar and chamfer edges. I turn the jog down to the right speed and angle the head. Pierce at the edge and start moving after it pierces. Saves cutoff wheels and grnger hours
That's an option, yes💪
wow bud i just watch 15 min so far n the fckin details you are puttin into it is just fckin nuts n crazy as specialy for a fckin rock crusher .... ole sayin '' its not a piano '' however its very rare you see guys workin on a project and actully really care on how they make it.awsome work n detail buddy , now back to video
At the next step,make a shrader.
It would be fun.
@3:08 is that a welder from the movies “Cars”? 😂
Nice. With the nuts welded to the back plate its easier to change the wear plate. If the heads get torn up just weld a nut to the head and take them out like normal
That's the easiest and simplest plan. I like your plan!👍🤙
Rebar is a soft metal. I would have put in a track pad off a excavator. Extremely hard material
Nice
Cheers!
Countersinking the mounting bolts for the main crusher plates would’ve been better to keep from breaking off during crushing but not you should consider hard facing the bolt heads to keep them from wearing down.
Hi! Great episode once again!
One question nags me though. What if the bolts heads are all buggered up from crushing rocks?
Would it make more sense to use lag bolts and fasten with locknuts from behind?
No. The plate moves in and out and that small amount of movement is what breaks the bricks. The rebar is the part that will wear first. I am not sure how long they will last yet Lots of people just weld like 7018 rod on to the plates as they need it over and over and over again. He has made these plates easy to remove and repair or build new ones. This makes taking the unit apart much lighter for repairs.
And I enjoy the urchfab references
Soovitan soojalt 3M cubitron 36+ fiiberkettaid faaside käiamisel. Kasutan igapäev ja teeb elu palju lihtsamaks 😉😉.
So the bolt heads in the crusher plate are activte part to the crushing work? Won't they wear out like the rebar and can become tricky to unscrew them for exchange?
Just a thought...
Thx for the update, awesome work!
:-D
love itd
When building a crusher, either the toggle is two plates joined with shear bolts, or a safety trip mechanism, on the toggle, is established, on the crusher wall behind the moving jaw. If you are crushing limestone, not required.
