I think a long reach excavator would be extremely helpful with build up and stuck oversize stones

[@the_1_who_sails_the_seasto367]

They have a big ass hook to unstuck boulders!

[@Engineer9736]

@@the_1_who_sails_the_seasto367 I think Kenny meant to use the long reach excavator Instead of that hook. Anyone who watched one of these videos knows that they use a hook at the moment.

Yep with a jack hammer attachment too... Thought this after 10 seconds into first video

[@bonsang1073]

thats how it done in actual mines, they have large baco arm with a massive jackhammer at the end. this place is but a quarry.

[@neptune4167]

Ive come to the realization, they dont want to free all that stuck material because that helps to protect the slide plates, I am sure it took a long time for that to build up and that build up now acts as protection.

[@HyenaEmpyema]

I understand your logic, but it's a zero-sum game: the more stuck material, the steeper the angle. Steeper angle = higher velocity. As velocity increases, impact increase by mass *squared*. So you save some tiles on the initial impact but sacrifice more tiles further down. However, this is further complicated by the fact that impact against the dirt is softer than a hard impact on a tile. So it's not that clear-cut. But there's also a risk factor. It's technically possible for the men at 3:40 to be buried alive by all that dirt. That all hinges on the economic value of these mens' lives, which sadly is less in LATAM countries than in the US. I'm sure the manufacturer of this crusher knows exactly how to maintain it, and maybe that does allow some buildup on the tiles. However, there are other videos from this channel where they remove the buildup using an excavator. So there must be some advantage in doing so. I'm not trying to start a war or say I'm right 100%, just opening this up for discussion. I find the physics and mechanical eng. aspect of this to be absolutely fascinating!!!

[@peteacher52]

Having seen Demolition Dave at work with explosives, I was wondering why a length or two of det-cord placed along the build-up, hadn't been tried. What an enormous machine, perfectly illustrating the concept of economy of scale.

[@Engineer9736]

I was thinking the same… They should have spend a bit of time with that crane hook to push the remaining ore into the crusher before starting maintenance

[@Glitch-nr9ct]

In *any* first world country there's absolutely zero chance that any living human would ***EVER*** be permitted inside that pit until those walls had been completely and thoroughly scraped of all loose sediment by a mechanical arm or water jet, then inspected. Un-friggin-believable.

When you need a heavy duty crane to remove individual parts, you know you're working on a mega machine. Buildup of compacted dust around in-feed looks quite thick. That might take longer to remove than the cone. What kind of ore did this crusher process?

At least they all have safety lines, but inertia reel systems would give them better ease of movement. I'm a little curious as to why they aren't using power hammers to shift the compacted debris instead of handtools.

[@brentmiller3951]

I absolutely hate the real systems it is possible they don't like them.I hate how they catch when you are not expecting it

[@ourfarmhouseinspain]

@@brentmiller3951 An irritating characteristic sometimes, I agree. Occasionally though - perhaps as here - they can be the better safety device. Arguable, isn't it ? I was a little more concerned to the degree to which they were unbalancing themselves hacking away at the debris with spades instead of having air or power lines run down to them for much more suitable tools. Much quicker and safer, and less overall risk of injury - which wouldn't be just a scratch, would it ?

Opening and hopper are covered with abrasion resistant tiles. Explosives or air chisels are damaging to the lining. It’s dangerous work.

[@mariotorres6287]

Forgive my ignorance, but why did they allow such a build-up to get to that kind of thickness before removal? And why by hand? A pedestal- mounted excavator with a hydraulic hammer or even just a bucket would make the job far quicker. I'd imagine the loss of production by the method shown here is huge. BTW, where is this operation located?

[@kahnwolfe9548]

The location is in India. As far as the cleaning, you can't risk damage to those plates that are the lining of the bin by using hydraulic hammers, and they have used an excavator on several occasions to clean down what they can reach with it, but that is also a very slow process as they have to not hit those lining plates. Because of the cost of the lining plates, and the difficulty to replace the lining plates, it is careful hand work to not damage it.

There is. We ran a small tracked loader in through the side of the pocket. Quicker, safer. Some of our neighbors used a long boom excavator. This would never pass MSHA. Being under the mantle when it's being lifted out would never be allowed. We filled the bin under the crusher with fine crushed rock for a walking surface.
