Hammermills are effective grinding a wide range of feed stuffs and capable of producing a wide range of particle sizes. However, hammermills can be noisy, dusty, and generate heat during the grinding process [11]. Roller mills can produce 1540% more pounds of ground grain for the same energy input compared to hammermills [7, 8,11].
