- ... Findings. Technological processes of reducing material coarseness such as crushing, grinding are the most resource-intensive operations of the mining and processing industry. Therefore, the use of the most effective systems of operational management of these processes is essential in modern conditions of operation of a mining and processing enterprise. A methodological approach to assessing the parameters of the linear parts of the control object model from the input parameters and the correspondence of the process values at the output of the control object are proposed. The analysis made it possible to determine and implement a management system for ore-shingle mills at an industrial enterprise. ...
