Setting the hammer tip near the screen can be beneficial with making fine grinds on fibrous or other tough to grind materials like meat and bone meal. For most grinding applications, a coarse hammer pattern with the hammers further from the screen will provide the greatest capacity and efficiency. Hammermill Maintenance Basics
mer mills are backed by over a century of experience in the feed milling and other related industries around the world. The requirements for grinding a large number of special products have led to the development of hammer mills that can be adapted to almost any application, regardless of whether coarse or fine grinding is required,
However, roller mills differing in grinding technique have not been compared. The aim of these four experiments was to compare a hammer mill and three different roller mills in grinding barley and wheat for growing pigs. In addition to mill type, the effects of fineness of grinding within each mill type were studied on digestibility, nitrogen
