Chapter 18. Feed Milling Processes

With dry solids, chance distribution creates disorder. When disorder is at a more or less stable maximum, it may be called random. Many factors in dry solids cause particles to avoid a chance or random arrangement. In fact, the result of mixing feed ingredients may be a definite pattern of particle segregation or non-random arrangement.
