An "ideal" smelter stack powered by its own train unloaders and loaders to take the plates and brick elsewhere. All steel furnaces, all belts compacted for full UPS savings. This thing kicks it out... I have yet to run out of resources in my ultra speed bot mall that is just fed plates by this.
10K Iron plates per minute 720 Steel plates per minute 7.2K Copper plates per minute 2.7K Stone bricks per minute
Couldn't fit it all in one image preview, sorry.
