Another common mill type uses a combination of both autogenous grinding and ball mill grinding—these mills are known as Semi-Autogenous Grinding or SAG mills. Water is added to the ore during the grinding process. This creates 'slurry', which is then used to transport the ore throughout the remainder of the extraction process.

Next, the grain is weighed. During the milling, or grinding, phase, the wheat is reduced to flour. Initially, Waterford's Old Mill used the movement of grooved burr stones to grind kernels of wheat. This grinding process removes the outer husk from the grain then powders it into flour. In 1885, roller machinery was installed in the Old Mill.
