How hard is it to change Maddy25`s coal unloader to woodchips? I looked at the 2 pulp and paper mills in my hometown on google maps and they both use a big mobile conveyor, like a Thor stacker, to pile the woodchips and then feed them onto another belt by loader. I can`t find anything like this on the dls so I`m either going to change the coal unloader or just shape a couple piles and use a woodchip texture on them. I`ve got what I need to make the feeder/conveyor for the mill ,just need an unloader.
