WhatsApp: +86 18838072829Introduction. Size reduction is an important operation in many food processing applications, of which a prime example is wheat flour milling. In flour milling, the predominant comminution tool is the roller mill [1], [2] in which the feed material is passed between two counterrotating rolls of, usually, 250mm diameter and with either a corrugated or smooth finish.

WhatsApp: +86 18838072829By adjusting the gap, the roller mill can produce a wider range of particle sizes, from fine flour to coarse feed. The consistency of grind is determined by the manufacturing quality and the number of rollers the material passes by. Higher quality mills will be sturdier, making the roller position more consistent, thus a more consistent grind.

A 2 roller has one set of rollers which takes care of separation of the husks and extract. Conversely, a 4 roller mill is usually used in larger scale distribution breweries due to its ability to increase extract yield by around 2%.
