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. All of these improve the ease of handling ingredients and their storability.

Application of value engineering techniques to grinding process modelling led to the identification of two basic functions of the ball mill-classifier circuit. In terms of a specified circuit product size which is used to differentiate between "coarse" or oversize material and "fines" or undersize material, these basic functions are (a) breakage of the coarse material and (b) removal of the fines.
