Abstract. Ukraine has approximately 300 to 500 ball drum mills in operation, which are used in various branches of industry. Most of them in factories works at partial capacity and on old or poorly modernized control systems. The complexity of ball drum mills control lies in various factors that affect the grinding process, namely: moisture content of raw materials, mechanical properties of the material, wear of armor plates and grinding bodies. At the same time, the influence of these factors without high-tech devices makes it difficult to control the grinding process, so with simple control systems operators work at lowered parameters for steady operation. Ball mills for grinding raw coal are considered. Experimental studies of ball drum mills operating modes in industrial conditions and on models were carried out. Mathematical models of grinding processes dynamics of raw coal were developed and research allowed to construct a system of optimal control of volumetric loading of a ball mill with stabilization of temperature of an air mix was carried out. A method of fuzzy adaptation of the controller setting parameters is proposed and rational control algorithms are chosen. Using the vibration acceleration sensor and the signals processing the volumetric load of the ball mill was calculated. The results of the study of optimal control system of ball drum mills volumetric loading showed high quality of control under various external influences. The control system allows to use the maximum performance of ball drum mill. An annual economic effect of $ 354,219 was obtained. Working design was developed, industrial tests were conducted and station control of ball drum mill was manufactured, implemented and put into operation. Parameters of explosion safety ensuring of a mill air mixture are established. The system of measurement and calculation of volume loading by coal of a drum of the rotating mill and maintenance of explosion safety of an air mixture of a mill is developed.

Keywords: energy resources, explosion safety, TPP, stations control, ball drum mill
