Hammer mills or roller mills are used to grind grain for feed for animal husbandry. The grinding process in hammer mills is based on impact stress on the grain kernels. Roller mills, however, apply pressure and shear stress. The different working principles in hammer mills and roller mills lead to different physical properties
