Abstract: Relevant problem of technological processes of crushing is reduction of specific expenses of energy (power consumption). And it is the most important for crushers, mills, etc., that is for the cars meaning shock impact on the processed material. One of solutions of this problem is the corresponding preparation of raw materials, in particular preliminary processing by cold. In this regard the purpose of our research is development of mathematical model with application of crushing of grain raw materials before crushing process. Creation of mathematical model begins with development of the general technique of a research of process of deep freezing and also a technique of its application. Further theoretical models which serve for determination of internal parameters of process and also features of processing of material when crushing are created. The final stage is development of recommendations for realization of crushing in the conditions of the enterprises of the formula-feed industry. The conclusion is drawn that freezing leads to change of coefficient of hydraulic resistance to the movement of the blade in an air and vortex layer, and in an air and grocery layer, coefficient of hydraulic resistance of the case of the grinder to rotation of an air and grocery layer and as a result to change of the power going for mixing of an air and grocery layer.
Key words: crushing, power consumption, grain raw materials, technological process, power, formula-feed industry, mathematical model, resource-saving.
