Senenu Grinding Grain, c. 1352–1336 BC. The royal scribe Senenu appears here bent over a large grinding stone. This unusual sculpture seems to be an elaborate version of a shabti, a funerary figurine placed in the tomb to work in place of the deceased. Brooklyn Museum. The basic anatomy of a millstone. The diagram depicts a runner stone.
The Egyptian hieroglyph ndj (nḏ) (Gardiner Aa27, U+13429 𓐩) has the shape of a cross.It presumably depicts some type of tool such as a mill.It is often written alongside the nu "pot" hieroglyph (W24). [1]
Higher speed means more grain is fed to the stones by the feed-shoe, and grain exits the stones more quickly because of their faster turning speed. The miller has to reduce the gap between the stones so more weight of the runner presses down on the grain and the grinding action is increased to prevent the grain being ground too coarsely.
Grist is grain that has been separated from its chaff in preparation for grinding. It can also mean grain that has been ground at a gristmill. Its etymology derives from the verb grind. Grist can be ground into meal or flour, depending on how coarsely it is ground.
Mo (Chinese: 磨; pinyin: mò; lit. 'mill') [1] [2] were stone implements used for grinding wheat in ancient China. [1] [2] It was a rotary quern millstone powered by a hand-operated crank fixed at the top to grind and pulverize grains, wheat, and rice into flour.
Semolina grains in close-up. Modern milling of wheat into flour is a process that employs grooved steel rollers. The rollers are adjusted so that the space between them is slightly narrower than the width of the wheat kernels.

Mining engineers, Peter von Rittinger, Friedrich Kick and Fred Chester Bond independently produced equations to relate the needed grinding work to the grain size produced and a fourth engineer, R.T.Hukki suggested that these three equations might each describe a narrow range of grain sizes and proposed uniting them along a single curve ...
