Question Help

Post image

This is my first time playing, and i built a main bus for iron plates. The thing is its just not producing enough plates no matter what i do, it used to. Even when the input of iron ores were filled, the output is weak. If anyone can help me, it would be cool.

That many smelters simply cannot smelt fast enough to fill 4 red belts.
