I got to assist in rebuilding one of these a couple of times 1984-1985 at Tilden and Empire Iron mines in Marquette County Michigan. No one wanted to run the crane to lift out or move back in the 135 ton mainshaft and mantle, so I volunteered. One of the easiest physically and most nerve wracking jobs involved. I learned how to run the crane on the job 2 years earlier. "Here's the controls, play with it a while until you get comfortable." Then, moving a bucket the size of a pickup truck in between moving conveyor belts and rotating mills with bolts sticking out 3 inches as it rotates. So, I learned early how to control swing early and well. ---- Anyway dropping the 135 ton bell into the eccentric opening was the hardest. Six people down in the pit staying aside but all trying to give directions. I set the controls down and yelled at them. Pick ONE person to give directions. The only directions the other 5 of you can give is to STOP. Then I picked up the controller and asked them which one is giving directions before we proceeded. As a worker, I'd rather be running the crane confident in my skills than be down below trusting someone else's skill.
The underside is ran on an eccentric, and has a bronz bushing thats about 40" tall ans 36" in diameter, the top is mounted in a flange that occasionally shears all of its big bolts and you have to lay out a new bolt circle by hand and re drill using a mag drill sitting a straddle of the cross member. And hand tap the holes. Its hard work. The gyro i repaired weighed 40k lbs.
I spent a few years of my youth working around and operating mobile crushers, Cone Crushers, Jaw Crushers, Roll Crushers, and Impact Crushers. Rebuilt and maintained many of them. Can be a quite dangerous business. I had MANY close calls.
@@bwatt1383 On a sub zero Winter night, I was sent into screening plant during night shift to clean screens...morning shift came on and started screen plant when I was inside...I barely got out. No lock outs on controls. Another time, we were "picking" a huge boulder that was stuck in jaw crusher...old worn out chain snapped and a large chain fragment hit me in the neck, just grazed me, had a shallow gash on my neck...a straight on hit would have likely killed me. Another time they had us clear back a bit when they blasted in a quarry. "Fly rock" landed around us, destroying the hood of one of our cars. A rock the size of a VW rolled into the crusher site. An inexperienced co-worker tried to manually turn a conveyor, grabbing the v-belt...operator turned on conveyor at that moment and the kids hand was mangled in the multi belt pulley. These are just a fraction of close calls I witnessed. My first shift, a night shift, I was handed a shovel and a hard hat...that was my only instruction. No safety hints, no explanation of what my job actually was, nothing. Most belt guards were missing around the plant....it was a miracle I didn't get hurt the first night...in the dark.
There is something about this machine. It seams alien like, horrifying, powerful, destructive and the strange noises and vibration must make it an eery experience to be around.
Very well put. For some reason i find it quite mesmerizing watching stones being crushed by a giant machine that i have no clue how it works. Very strange indeed.
I agree it seems to be really under powered! I know those rocks are bigger then they look on camera. Would be $$ but an intergraded arm with hydraulic hammer would speed it up a lot.

Everytime i watch I'm amazed that with all the $ and capabilities that must be present at this site, the best they could come up with is the world's slowest hook for free-up the jams.
I suppose, considering they need something that can manipulate car sized boulders and lasts forever might put some limitations on their options. It would also be pretty heavy and have to reach quite a ways. Given that those dump trucks are 20 feet high, about 25 feet wide and 40 feet long, I would guess it's over 100 feet to reach the mouth of the crusher.

Now I know where George Lucas got the inspiration for the Sarlacc. What I really want to know, however, is what makes this thing move? We're talking about some titanesque forces here!!!
The top of the big cone is in a fixed position, but the bottom is attached to a point that moves around the center point so the entire thing rocks around in a circular motion. There is lots of leverage to the point the rocks get pinched and crushed.
Back in my day , we didn't have these high tech - new fangled rock crushing machines. We did all the work ourselves, and if you didn't work , you didn't eat. We didn't have any of them fancy shmancy hammers either. We used our fist and when our knuckles was all busted up and our bones was showing we used our heads and when we had so much blood in our eyes we could no longer see old man smithy ,the town drunk would lead us over to the new pile of rocks waiting to be smashed , and dog gone it, we liked it.

Brains?? A flat hook, dangling from a crane, is the worst tool to remove rocks that are stuck in a poorly designed pit. The hook cannot even be turned around. What a waste of productivity.
@@zottek2 Hey you still gotta have lots of guts and nerve to try creating machinery of this size. Not to mention operate them, fix, install, uninstall, it is no easy task you dumb fool. That's why I said brains, it is also required and it works. What else you need?
My uncle and I ran the Gerry Shaft crew on a Schmidt P5000. Every three days we'd have to strip it down and recalibrate the Kimble. It was hard work but I do miss those days.
We rebuild lots of crusher parts where I work. That piece that spans over the top of the cone is called a spider, and the cone is called the main shaft. The most worn-out spider I ever worked on was twenty feet across and had arms worn so thin that we were burning holes through it when we started welding on it to build it back up to oem size. We put thirteen 1000lb barrels of 1/8 inch diameter weld wire on it and probably 15-20 33lb spools of 1/16th wire on it, all by hand plus several hundred more pounds by machine to build up the bores and fits so that it could be re-machined to size.
The pestle is most likely hardened steel. The motor is in the sphere at the top I don't know this for certain but it most likely works like the vibration motor in your phone. There's a shaft that goes from the top to the bottom, inside the pestle, and as it spins, it causes it to shake back and forth, grinding the ore.

Looking at the cut of the hopper as well as the amount or type of bulk material that is filled into the hopper, I have a very bad feeling about the thought that there could be gear damage in the grinder. I imagine the repair and its preparation to be extremely costly.
The built up material is to prevent wear on the metal hopper. The engineers figured out that it is better to wear out rock than to wear out metal bins and chutes. There are wear bars bolted or welded onto the walls but really the only time they are exposed is when the sides are cleaned out for maintenance. The only real wear is to the bell shaped mantle and the concave where it is narrowed down by the mantle and of course the spider that holds the top bearing. After being crushed to size it lands on another bed of built up rock and then overflows onto a conveyor belt.
Crusher is made out of steel. The Iron in the Iron-Ore is sparking. Think of all the sparks grinding some ferrous material. You can sometimes spark hitting a chisel with a hammer as well. The orange glow is probalby just a sodium vapor lamp on the lower level at the conveyor belt.
It´s not space shuttle tiles for reentry heat dissipation nor they need to be an electrical isolator. Think twice! What happens when you drop your dishes to the ground? It´s brittle. So throwing tons of stones onto brittle Ceramic wouldn´t be a good idea IMHO. The Panels are made out of steel and are covered with dust, therefore the ceramic look.
Iron ore as it´s said in the video title. Probably just a sodium vapor lamp in the basement area for the hellish orange light. A furnace would only make sense for iron ore pellet drying after refining. But thats a long way of sorting, chrushing, grinding ...

Is the iron instantly smelted after crushing? Cause I see something glowing down there.
The ore will be processed into pellets and then shipped by rail or boat to a steel mill for smelting into steel.
I thought that too but if you watch other videos they posted you learn its an orange light bulb. No fire.
I bet some of those rocks get in the right squeeze position between 2 other rocks they would come shooting straight up like popping a pimple.

You can sometimes spark hitting a chisel with a hammer as well.
The orange glow is probalby just a sodium vapor lamp on the lower level at the conveyor belt.

The call of the crusher, once more brought me back here.
I turned the playback speed up and it was fun to watch, like watching a fire in my fire pit with a beer.
How does it generate such large crushing forces?
You need a couple of air vibraters on the hopper to shake the the fines so they don't stick they use them in cement plants a lot
I like how they made it look like a disco ball
