Still, it seems a little counterintuitive that it's not worth putting up an edge or something.

- refurb 13y agoIf it's crushed rock, i'll bet a lot of the spillage is dust and small rocks. After a few years it adds up!
- kijin 13y agoIf they poured crushed rock directly onto the belt, not much would be left after only a few kilometers, what with all the curves, slopes, and vibration. The belt will also be damaged beyond repair if you keep rubbing rock against it. So they probably put the rock in boxes and put the boxes on the conveyor belt. The tiny guardrails on either side should be enough to keep the boxes on the belt. Small pieces might spill over if the boxes aren't covered, but most of the cargo will arrive intact.
- tlb 13y agoHow would you get the boxes back to the beginning?
- YokoZar 13y agoHang em on the bottom of the conveyer belt!
- saganus 13y agoWell, you put another conveyor belt going in the other direction of course. Then you will have the TWO longest conveyor belts in the world. Ka-ching! [Edit: Typo]
- bcoates 13y agoRe-use them for shipping out the finished product, so they become someone else's problem.
- garrettgrimsley 13y agoThey don't have it in boxes. There are also no guardrails. You might be looking at the conveyor belt in the picture with trees. That's not the Bou Craa belt. Check out this video of a 10.5km limestone conveyor belt in China [0]. Notice the rollers have a tilt to them? I found a better photo of the belt itself on PBS. [1] if you look on the left hand side of the photo you can make out a cylindrical object beneath the belt. That is the roller, it has the a tilt to it, just like the Chinese belt. Any vibration will result in the load gathering toward the bottom the the belt. Most of what we see on the ground is small particles that are swept off of the belt by wind (Used to live near a port and a concrete factory. Lovely air quality, S&W Ready Mix.)
