Ded Driver said:yeah coal has to be handled a bit more gently, but the volume of iron ore coming in from around 250 or more wagons needs a fast unloading method. This would pulverise a lot of coal, so bottom dump is the go, although there are side-tip wagon systems (similar to side-tip semi trucks)
Not so gentle. It drops many metres into the loading bin, then falls a few more metres into the rail wagon. At the dump station it again fall several metres before hitting the conveyor belt at the bottom of the bin. Next it is dropped out the stacker. The big yellow thing in my pic above. Next it is scooped up and shot into a ship via the ship loaders. I imagine it goes through a similar process to be unloaded, stored then sent to the furnace.
