The efficiency of the ore grinding technological process is mainly conditioned by implementation of separate operations ensuring it. The sequence of carrying out those operations is determined by the technological scheme topology used in that process. The topological scheme depending on the peculiarity of organizing the production process, characteristics of power consumption regimes can be modified. As a result, it becomes necessary to carry out the calculation of the technological scheme modified for this or that reason, the investigation and analysis of the technological situation for the new scheme. That is why, in the present work, an algorithm for investigating the scheme used in the ore grinding technological process ensuring the automated reproduction of the technological scheme topology and a successive calculation of operations included in it is proposed. By analyzing the parameter states of the vector characterizing the properties of the input flow of the operations included in the technological scheme, the closed cycles and feedforward of the scheme have been revealed. To determine the parameter values of the circulating material, the total disagreement function has been reduced. The proposed algorithm has been tested for a closed cycle one-phase and two-phase schemes of ore grinding. The results of the test have confirmed the truth of the developed algorithm. To implement the proposed algorithm, a program has been developed allowing to investigate and estimate the closed cycle grinding technological process for the selected technological scheme, mills of different types, classifiers, as well as in case of grinding ores of different qualities.
