A three roll mill utilizes high shear force to disperse agglomerates, and homogenize viscous materials. Shear force is created by three horizontally positioned rollers rotating in opposite directions and at different speeds relative to each other. The product is pulled through the gaps between the rollers.

A three roll mill has three different fast rotating rollers of the same diameter. The middle of the three rollers is stationary. The infeed roller and scraper roller can be moved toward and away from the middle roller to achieve different gap widths. The speed ratio of infeed roller (a) : middle roller (b) : Scraper roller (c) is approx.. 1:2:4.

Pros of Two Roller Grain Mills. Two roller mills are substantially cheaper than three roller mills and provide adequate results for the average homebrewer. The benefits of a three roller grain mill can largely be achieved by running the grain through a two roller mill twice. This makes the price savings worthwhile for homebrewers on a budget.
