09.14.2021. By Arvin Donley. It's been said the first flour miller was the first person who chewed on a wheat kernel. While the details of that milestone will never be known, we do know the transition to using millstones instead of molars to extract flour occurred around 6000 BC, and it remained the primary flour-making method for many centuries.

Sieving machines and mills are used to mill solids to reduce their size. This fulfils two purposes: first, it enlarges the particle surface, which increases the speed of dissolution. Secondly, it evens out differences between particle sizes to ensure homogenous mixing. Owing to their versatility, milling and sieving machines play a crucial role ...
