English abstract

The object of the research is the processes of managing the technological redis- tribution of ball grinding of iron ore at ore processing plants in closed cycles, includ- ing a mill, a mechanical single-spiral classifier and a spiral feeder. The subject of the research is a complex of automated systems for the implementation of energy- efficient invariant control of grinding and classification of ores as part of the auto- mated process control system of the first stage of ore preparation based on the de- veloped methodology and indirect predictive estimates of the characteristics of raw materials and equipment. The methodology of the article is considered as a set of research methods in accordance with the specifics of the object of knowledge and is based on the principles of the unity of theory and practice, certainty, concreteness, recognizability, objectivity, causality, development. The aim is to increase the effi- ciency of the ore preparation technological process by applying a new developed methodology for the implementation of energy-efficient invariant control of grinding ore classification based on indirect predictive estimates of the characteristics of raw materials and equipment. It is shown that the system of selected methods, including a number of general scientific and special ones, as well as those proposed (more than 20 methods), makes it possible to solve the overwhelming majority of general issues of the implementation of energy-efficient invariant control of grinding-classification of ores, which increases the accuracy of assessing technological parameters and, as a result, quality indicators. control processes within the framework of technological requirements. It is proved that a ball mill can be represented by the initial and main parts of the drum and ball loading, and the mechanical single-spiral classifier can be represented by a double-pass spiral, the upper part of the spiral with a sand product and a sand gutter, a classifier basin with a lower part of the spiral and a drain threshold, which are independent. autonomous systems, where processes run independently and practically do not affect each other, which will allow the use of independent automatic control systems and the ability to take into account additional useful connections be- tween controlled processes, which will lead to a further improvement in the quality of the complex of systems.
