The new mode of milling was much faster and therefore more economical than stone milling had been. In the roller milling process, the grain is ground into middlings, which are then sifted by hand and reground. The extensive amounts of sifting to remove the bran and the germ required a large labor force.

Principles of modern milling are much the same as they were many years ago using rotary grinding stones, except now wheat is ground between pairs of cast-iron rolls before the stocks are sieved and then reground. Wheat milling consists of several processing stages. These stages are wheat intake, pre-cleaning, cleaning, milling and packing.
