CHAPTER 11 SIZE REDUCTIONRaw materials often occur in sizes that are too large to be used and, therefore, they must be reduced in size. This size reduction operation can be divided into two major egories depending on whether the material is a solid or a liquid. If it is solid, the operations are called grinding and cutting, if it is liquid, emulsifiion or atomization. All depend on the reaction to shearing ...
