Choosing the Right Mill for Your Craft Distillery ...
As the hammers pulverize the grain, it is forced through the screen. Overall, hammer mills tend to produce a finer grist. The benefit of hammer mills is that screens are available in different mesh sizes, meaning you can, at least to some degree, adjust the particle size of your grist and ensure that it comes out more uniformly.

Hammermills versus roller mills | ...
In a hammermill, the screenhole diameter controls the maximum finished particle size of any ground product. When using roller mills, there is no screen being used, and unless the product is sifted and the coarse fraction reprocessed, the resultant particle size is purely reliant on the miller's skill in setting the roller mill effectively.

How to Determine the Size of a Fine Grind
· The screen found at the end of the mills' discharge opening is usually made from steel. The screen includes holes or perforations in a wide range of sizes. The size of the holes or openings determines the screen size required for electronic scrap. Based on the productivity goals, the screen size can be in inches, millimeters, microns or US mesh.

Hammer mills: hammermills
Screen Design The amount of open area in a hammer mill screen determines the particle size and grinding efficiency. The screen must be designed to maintain its integrity and provide the greatest amount of open area. Screen openings (holes) that are aligned in a 60degree staggered pattern optimise open area while maintaining screen strength.

Reducing the hammer mill screen from 3mm down to 2mm reduced average particle size in all three grains (wheat: 639 and 552 µm; sorghum: 654 and 602 µm; barley: 676 and 639 µm respectively for the 3mm and 2mm screens). Durability of the pellet was superior when sorghum was excluded from the diet, regardless of hammer mill screen size.
