In the mining and metallurgical industry, in addition to raw materials, the quantitative volume of technological operations has a significant impact on the cost of the extracted metal. As practice shows, the most energy-intensive process is crushing of rocks, which accounts for 30-50% of all production costs. In this connection, the management of this process is one of the main technical and economic factors in the chain of rock dressing. In this paper, the mathematical function of the ball mill MSHTs 75×55 is derived, on the basis of which a computer model is built in the SIMULINK subsystem of the Matlab software package. As a result, the transient and impulse characteristics of the mill were built, and the stability of the system was determined from the calculated transfer function.
