The 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 SAG Mill has four output slots; recipes can have 1-4 different outputs, with different chances of obtaining those outputs.

Autogenous grinding (AG) and semi-autogenous grinding (SAG) mills use the material to be ground as the grinding media. Autogenous grinding mills use larger rocks to impact and break smaller rocks as the mill rotates. Semi-autogenous mills are basically the same autogenous mills, but with the addition of balls, similar to those in ball mills.

The "Critical Speed" for a grinding mill is defined as the rotational speed where centrifugal forces equal gravitational forces at the mill shell's inside surface. This is the rotational speed where balls will not fall away from the mill's shell. Result #1: This mill would need to spin at RPM to be at 100% critical speed.

SAG milling is arguably the most commonly used method of comminution in mineral processing. So why are so many SAG mills operating sub-optimally and why are they considered to be so difficult to control? Operators often consider the basic controls provided during commissioning are as "good as it gets."

A semi-autogenous grinding mill, or Sag mill, is responsible for grinding materials from large chunks into small, usable pieces for processing. The Sag mill is usually part of the primary stage in the grinding process. Pieces of raw or fairly reduced materials are ground into smaller pieces for further processing or sorting. These machines are ...
