Published on Mar 20, 2017 In this Factorio Workshop, we go over a Smelting Setup / Design made by MadZuri. It uses some smart circuit logic to easily control the requests within the smelter and set the entry signals to let trains in based on how much ore is in storage. Very compact and smelts about 22k plate per minute.
