Here are some of the main things to consider when choosing a mill: Number of rollers. A threeroller mill works by passing the grain through two gaps. The first breaks the grain's husk and the second grinds the grits. Threeroller mills protect the integrity of the husk which helps with the lautering process. A tworoller mill has just one gap.

The 3roller mill has several advantages and few disadvantages. It has greater output than a 2roller model running at the same RPM. It provides less husk damage, which aids in sparging. Also, the 3roller mill more fully separates the starch from the husk, while providing superior grain feed, even with wheat.
