Chapter 18. Feed Milling Processes - Food and Agriculture ...

Grinding or particle-size reduction is a major function of feed manufacturing. Many feed mills pass all incoming ingredients through a grinder for several reasons: (a) clumps and large fragments are reduced in size, (b) some moisture is removed due to aeration, and (c) additives such as antioxidants may be blended.
