Just needed to put my two cents in. I used to run a 1200tph version 15 years ago. A number of people have commented that they could feed a lot faster. As they are doing here you don’t want to bury the top/spider cap. Then you want to let it empty before the next load. Generally it takes 12 hours to dig out if the crusher bogs. They have a much larger bottom gap than I’ve ever seen which speeds up flow alot. Underneath there is a big hopper called a surge chamber around 4 stories deep. Ours used to have sensors that put on a red light at 90% to stop dumping. Green when it dropped to 70% and stopped emptying at 30% to protect the apron feeder that feed the crushing circuit. An apron feeder is like a large steel bulldozer track the will feed at a set speed. Ours could be manual or normally linked to the secondary crushers amps. So even though the primary could do 1200tph the secondary would do around 550 to 650tph. There was 10 belts and 2 screens in the circuit to crack those big rocks down to 45mm or 1.5 inches.
Standing under one of these guys as its doing its job had to have been one of the most intimidating things I've done. You can just hear how easily it breaks down the bigger chunks... No you can feel how easily it breaks them big chunks
Drove one of these bad boys on a stone quarry, our crusher wasnt so big, and it was a square one. Dumper takes 400 liters of fuel and lasts 24 hours only :P
Easily dealing with 4 trucks in 10 minutes, this crusher could be doing 2400 tonnes per hour, 2000 without breaking a sweat. Limiting factors may be the conveyors and the number of haul trucks and excavators. At current prices of around $200/tonne, these are important issues.
I seen on another channel a truck unload a lot of rock into the gyrator , in fact it was two trucks. How come these trucks are not loaded heay like the truck I seen?
Johnny Murff looks like the conveyor system is the bottle neck. I don't think they could run much more through the crusher without overloading the rest of the plant, perhaps.
I noticed that one of the skip loaders had a residual load which never fully emptied. Over a work day that may have amounted to 5-6 loads of wasted time and fuel.
@@lohphat Well some of the load sticking is a good thing it saves wear on the tipper body. The same idea is used at the crusher itself but you do have a point that was a big lump, maybe time for a scrape from a bucket.

I came back, and back, and back, and... love so much this video seeing the unloding of those huge trucks
Thank you for the video , Love it !!!

What is the siren for?
It's like watching fire.....very mesmerizing!

Good video footage like to see this, iron ore material being unloaded into the cone crusher, keep it up with
This is AWESOME!!😍I love huge dangerous machinery.
you must be fascinated with the dumping but not so much with the cone crusher

Interesting that the heated beds of the skips aren’t clearing all the dirt out when it tips. It must be well sticky stuff.
great
Beautyfull midnight!
impressive power
Enjoyed this, how often do you clean the hopper and the truck trays?
Not very often by the past videos I’ve seen.

Those Komatsu's sounds like old Detroit diesels.
Those Komatsu,s are triple 777 cats with one hundred tonne capacity
@@malcolmmckinlay2143 I was thinking about the one visible from 22:36. I would believe it's Komatsu's as the logo states so :)
Какое это предприиятие, где находится, какой уровень оплаты труда в долларах США!? РАССКАЖИТЕ ПОЖАЛУЙСТА!
Eu só não entendo oq são feitos com tantas toneladas de pedras?
Where was this filmed? southeast asia or india?
The About section says India.
Surely it got to filled quicker for efficiency. Seems to be way under its capacity?
No back up or forward horn sounds
Why never clean The crucher
Not the best one seen. Obviously the interest was meant to be the trucks this time.
