The aggregate from that quarry is known for producing high-quality concrete with high strength and low shrinkage. I was on a concrete placement for the aprons at Oakland airport. The concrete used 1-1/2" Aromas granite aggregate. The aprons are two feet thick. I went to a July 4th party at that quarry about 30 years ago. Peter Noone of Herman's Hermits performed. He lamented that he was performing in an effing quarry.
Funny story about the performance. Thanks for sharing both the airport particulars and Peter Noone's lament. I saw a similar event at a wedding party. During a break, a well known concert pianist somewhat lamented to me he felt offended that people continued their conversations. I hope I 'got through' to him that people came for the WEDDING, the Bride, the Groom, and the social circle of friends sharing some time together. Given the venue's purpose, his performance, no matter how good, would automatically receives second (or lower) billing.
1:36 For 300 years, Krupp was the backbone of the German military, from the 30 Years' War to WWII. 3:33 Don't they compact their waste mountains? 12:00 When I was a kid working at a large rock crusher, we would use metal wedges attached to a cable to move stuck boulders in the crusher jaws.
As a retired heavy equipment operator that's worked with crushers , I see lots of fines in those buckets going into that portable crusher. If that was pure stone, those producing numbers would be alot lower. I enjoy these videos but I will point out the obvious.
That’s exactly what I thought. This buckets are full of fines. I do wonder if it does have the ability though to crush rock face at that tonnage hour as well. I couldn’t find any facts about it elsewhere.
@@becauseboost4726 I guess that you never worked around or fed a rock crusher. As fines totally bypass the crusher parts of the machine. And pure rock almost all goes through the crusher.
I guess that you can't read the second part of his comment. If the material is all rock it must be crushed and slows down the process where as mostly dirt bypasses the crusher which would give you less tonnage per hour. . Obviously you're another one that hasn't a clue.
Thanks for the video. It makes a lot of sense to pre-filter the 'fines' out of what the crusher must deal with. Yet what is shown at 0:13 and 0:27 is that the cone crusher is being fed with a mix that includes fines. Perhaps they sometimes deliberately admit fines when they wish to increase the percentage of material that is ultimately reduced to 'fines'?
to start with I was like "Ah cute, they use the same cat 988H's the quarry I work at does, that must be huge for a mobile" then i saw its a 992 and realised this is a huge freaking mobile crusher
I live about 30 minutes from here and used to pass the quarry about once a week. Make a trip to Kirby Canyon between Morgan hill and San Jose. Stevens Creek quarry in Cupertino.
Reminds me of the work i use to do, back in Nevada gold mines, Ely, Winnemucca, Battle mountain, we built the cone, and jaw crushers plants here in Sacramento ca, assembled them , worked the bugs out of them , dissembled them and had them trucked the the versus mines, then reassemble for operation, samething with the convayors (grasshoppers) lots and lots of cutting parts, welding, miss those days that was back when US Machinery was in business
Very cool tunes on this episode. I really enjoy this channel; I'm a nurse now but I used to drive 170 ton Euclid haul trucks (end dumps) on Black Butte Coal in southwestern Wyoming back in the day. I've also been an oiler and plant operator, so watching these vids takes me back to those days. Keep it up, Aaron!
2:03 They are driving on the right side of the road so I am assuming they are not a mining operation and not under MSHA rules? Left hand side so trucks are not cab to cab I thought was the standard.
Great video! It's fantastic to see the company going so well for so long 💪🏼💪🏼💪🏼 surprised to see so much Germany engineering there! But I still bet there's plenty fitters have jobs here 🤑🤑🤑 And mobile tracked crushers AND screeners are VERY Common more mobile tha this old yolk 😊
Great video! As a Dutchy hearing you say "Mah mo hat" makes me giggle! Also, this video made me again wonder why not more quarries use conveyor belts instead of hauling everything with expensive big Trucks. To me a good conveyor belt (after initial installation) seems a lot more efficient than all those trucks, all the diesel, the personel, etc.
That primary crusher isn’t a cone crusher, it’s a gyratory crusher. Whole different mechanical principle. Cone crushers are used after the primary crusher as a secondary, tertiary crushers down the line to make the final products.
I worked there for years ago as a heavy equipment mechanic for local 3 Union I like working for granted I was a paver mechanic for them on the freeways on I-40 in Fresno brawley and the top of the grapevine it was a great company
What I don't understand is how the loaders are dumping already crushed granite into the big crusher. Where does that come from? The video says from the scrapers, but how do the scrapers load granite? I remember Aaron visiting Chris Guins (Letsdig18) in NC a couple of years ago, and him coming across as a bit of a dork. He had a nerdy catch phrase about making dirt look pretty, which was totally cringe making. Sorry Aaron if you read this. According to Social Blade, you are making a lot more money than Chris from TH-cam with a lot less subscribers, so you must be doing something right.
the rock is blasted then ripped / pushed by dozers before it gets to this point. It looks fine because the equipment is so big, but it's plenty rocky as it's being fed
Didn’t see a lot of rock going into that crusher….. those 992’s were dumping gravelly material mainly. I suppose after all these years they have to pamper it a bit with easy to digest material. Grampa’s teeth aren’t what they used to be.😂

this channel is basically Mighty Machines for adults!
I'm glad you think so
Best tv back when I was younger
An extended video with the B roll from this visit to a quarry and the other one you visited down near San Diego would be great.
Which one Robertson
@@terryjones2982 The one with the CAT D-11. You'd have to go back in Aaron's videos from a couple years ago.
Andrew Camerata’s next purchase
I want to see him bring that thing up his driveway and then fix it up so it won't break in the next 100 years for no reason.
hahaha that's what I was thinking too
I can tell you the Hagglunds on that crusher is at least 500k
@@ViperLemondemon That seems rather cheap tb fair
lmfao
It's amazing to see the equipment working that builds our modren world😊
Finally some actual crushing! Should definitely involve the plant side in your videos more.
Insane... I was more impressed with the wear plating on those 992 buckets... LOL!!!
1:36 For 300 years, Krupp was the backbone of the German military, from the 30 Years' War to WWII.

Cool, I knew they were in WW2 but I didn't know they were around for 300 years
Another great video. I hope you got some good hill runs in while videoing this massive mine. Beautiful country.
thanks for watching! I'm always running
@@AaronWitt All the best with your running. Any marathons coming up this Fall?
Wow, the sheer size and power of that rock crusher is mind-blowing! 🔨

Im in a stone processing facility probably 3 days a week on average and I have never seen wheel loaders with wear packages like that on the buckets
Hey Aaron you should check out the videos of the dozer's trying to keep the lava flows in check in Iceland. They have the largest blades I have seen!
I live about 30 minutes from here and used to pass the quarry about once a week. Make a trip to Kirby Canyon between Morgan hill and San Jose. Stevens Creek quarry in Cupertino.
Funny when you have to hire a moving company to move a mobile piece of equipment. 😆

that's awesome
Great video!
So they had to move a mobile machine one mamout trailers?
And they still use trucks to bring material to the crusher?
they used Mammoet because they can't move it such long distances and down such steep grades
@@AaronWitt ohh okey thanks (:

That’s awesome thanks for watching
You guys have to come to Freeport in Safford or morenci !!
Think it would be funny if he went to asarco ray or FMI Chino instead
Impressive operation
seems to be alot of fines in that material being loaded into the crusher. do they do blasting to obtain the rock ? otherwise how do they get granite ?
Correction Aaron - it's a gyratory crusher. Cones are similar, but have an inverted shape! Great breakdown as always!
I am good at being wrong
Now that's a good intro. Teach the people somethin rock on buddy
2:03 They are driving on the right side of the road so I am assuming they are not a mining operation and not under MSHA rules? Left hand side so trucks are not cab to cab I thought was the standard.
it depends on the mining operation / location in the pit
As someone with no knowledge of mining this is great i love it
11:25 So it's like a giant mortar and pestle?
Great video! It's fantastic to see the company going so well for so long 💪🏼💪🏼💪🏼 surprised to see so much Germany engineering there! But I still bet there's plenty fitters have jobs here 🤑🤑🤑 And mobile tracked crushers AND screeners are VERY Common more mobile tha this old yolk 😊
so what happens to the waste thats too fine? is it what leaves on the outgoing conveyor or is that for the crushed stone?
Love your videos. I love watching the large mining machinery at work.
Is that crusher diesel or electric? If electric, why do they start at 4 PM.I would think they would start at 9 am for solar max.
Wish you could come see an actual Primary stone crusher. That little portable plant is tiny lol. Need to see a GYRO CRUSHER
Hope you got a burrito at Marshall’s market while you were there lol
Are you wearing Ariat’s?
Great Video. Just one correction, the Spreader, "Big Bill", was made by Mitsubishi, thus it's Japanese, not German made.
Also, the KRUPP has a gyratory crusher not a cone crusher

That stripping operation is nuts! Where I live, that dirt is worth $40/yd (cause we don't have any).
It's clay
@@tomlorenzen4062 :D We still call that "dirt" in my area. We strip about 4" of surface-detritus, then we're on solid limestone.
That primary crusher isn’t a cone crusher, it’s a gyratory crusher. Whole different mechanical principle. Cone crushers are used after the primary crusher as a secondary, tertiary crushers down the line to make the final products.
Question. At what point do you call a rock a bolder. ? 🤔
Half that tonnage if you account for the constant fines going through!
My dad had a couple of these when we were kids
I worked there for years ago as a heavy equipment mechanic for local 3 Union I like working for granted I was a paver mechanic for them on the freeways on I-40 in Fresno brawley and the top of the grapevine it was a great company
Why did you stand behind the sign and what's with the wiggly really
So its a mobile crusher thats not mobile 😂
Santa cruz mtns! my neck of the woods.
When are you going to Camarata and see what he's doing?
what a operation
Wowww!!!!😮😮😮😮
This is a Gyratory crusher.
This video made me think Why now BWEs in the USA?
Never actually showed the crusher
did you even watch the video lmfao

Great vid. Your pronunciation of "Mammoet" is horrendous though lol
I'm a dumb american
@@AaronWittGood One 😂😂
Where are the rocks ,its just fines and pebbles .😀😀😀😀😀😀

Thanks, most people watching don't have a clue between rock and fines.
they had a lot of fines this time because they're saving most of the bigger rock for a huge order of riprap they're producing
Hmmmm, the term "stripping operation" reminds me of something else... 😂😁😜
