Around the late 18th century, the milling industry dramatically changed with the invention of the roller mill - a type of machinery with a series of rollers that grain passes through to separate the endosperm from the bran & germ, leaving behind a white, fine, starchy flour. This not only created a softer, more palatable flour, but more importantly, it sped up the …

Roller mills use the centrifugal force of cylindrical grinding rolls to crush material into a uniform particle size and grind, dry, and classify. Some of its typical applications include the grinding, drying, and classifying coal, gypsum, limestone, clay, barite, pearlite, clinker, food products, grains, ores, and more.

 — 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. Then, in 1779, at …

 — While the process of developing roller milling came into existence in the 19th century, it took an industrial revolution to make roller flour mills the most common flour mills today. The arrival of automatic machinery, forced by steam and like electricity, put the wheel of grain processing on the move, achieving higher yields and cleaner flour ...

 — Screw Mill/Tahona (83.86): This is a combination that will speed up the tahona process. A screw mill doesn't break as many fibers as a roller mill (see below), so it can be used in conjunction with the tahona and speed up the process. Screw Mill (82.9): When used all by itself, a screw mill is an efficient compromise between tahona and …

 — However, the roller mill caused the formation of long bulgur particles. This problem could be solved using different feeder over the rolls, or recycling screen to separate and re-feeding into the mill, or double or triple roller mills, or a hard polisher etc. The roller mill is a famous mill used in flour and semolina industries.
