### Simple SAG Mill - Official Feed The Beast Wiki

2021-8-4  The Simple SAG Mill is a machine added by Ender IO. It uses Micro Infinity (µI) to grind (or mill) items into their crushed variants, like Ores into Dusts. The Simple SAG Mill has four output slots; recipes can have 1-4 different outputs, with different chances of obtaining those outputs. Similar to Ender IO's other Simple machines, capacitors cannot be used in the Simple SAG Mill, so its ...
