The operation of the crushing and milling complex is determined by large number of factors, many of which are random. Each combination of factors corresponds to a certain technical and energy regime of the complex. The more fully the factor field of system properties affecting operating mode characteristics is taken into account in the operational control, the more efficient the control and the lower the energy consumption of the crushing and grinding processes. However, increasing the number of factors taken into account increases the complexity of the model due to the complexity of the system topology. Therefore, in the management it is necessary to form a controlling influence, finding a compromise solution that takes into account the range of informativeness of the factor field and its complexity.
