Abstract
The process of material jet grinding is analyzed from the point of view of the granulometric material composition changing in the main elements of the grinding plant. A database of dependencies connecting the technological parameters of the process and the acoustic sig-nal characteristics of the mill operating zones has been created. The advantage of the ap-proach to building mathematical models and creating an automatic control system based on the developed database is the ability to accurately describe most of the factors affecting the grinding efficiency, the possibility of describing with the necessary details for specific mate-rial grinding and obtaining the required size of the ready product. The use of connections between acoustic signals and technological parameters makes it possible to take into ac-count the patterns of changes in the material particle size distribution during the passage of the flow in the grinding plant channels and respond to changes in the product quality or the grinding mode on-line, without wasting time on transport delays.
