The two mean diameters agreed well, pointing to the fact that either mechanical sieving or particle imaging can be used to characterize particle size. Specific energy input to the hammer mill increased from 1.4 kWh t−1 (5.2 J g−1) for large 25.1-mm screen to 25 kWh t−1 (90.4 J g−1) for small 3.2-mm screen.

A 2-roller mill is the most basic, entry-level model of mill used in many smaller craft breweries. With this type of mill, an adjustment to the 'mill gap' can be made to optimize the brewing performance of your malt based on the grist particle size analysis. You can purchase the required mesh sieves for grist size analysis from Seedburo.
