“…Solid particles polluting oil in hydraulic transmissions can have environmental nature, e. g. when a machine is working in a dusty environment, and get inside the mechanism through filters, tightenings, and valves, or can be a product of transmission elements and units wear off [16,17]. It is also worth noting that in laboratories, the oil pollution level is often analysed with the use of spectral analysis [18,19] and the assessment of quantity and quality of acoustic signals [20].…”

Mechanization and development of mining machines increase the importance of maintenance quality of working bodies and the machines themselves. This requires implementing improvements in technical maintenance processes. Improving technical maintenance implies the implementation of condition monitored maintenance that also allows real-time monitoring of the technical status. As hydraulic oil pollution is one of the major causes of breakdowns, it is recommended to implement oil pollution monitoring methods that will allow estimating the real-time oil pollution level. Today, sampling is the most widespread method of pollution level control. This method is time-consuming and that is why there are many attempts to devise new methods of monitoring the real-time oil pollution level. One of such methods includes recording of the acoustic-emission signal. In this work, we suggested that increase in transmission oil pollution level leads to increase in acoustic-emission signal in 20-300 kHz range. This increase in the acoustic level will indicate the pollution of oil with solid particles and alert the maintenance crew of the necessity of replacing the oil. This method allows real-time monitoring the hydraulic oil condition not associated with high labor, time, or economic costs.

Currently, improving the quality indicators of mass production and consumer goods is impossible without the use of modern software systems, means and methods of automation. The main systems capable of satisfying the tasks of modern enterprises and scientific organizations include Scada-systems, which provide the necessary control accuracy and versatility in conditions of low costs for additional staff training. Consider the prospects for improving the technical and economic indicators of metallurgical and chemical enterprises through the introduction of automation, on the example of the operation of concentration plants. Obviously, the main tool to increase the economic efficiency of production is to reduce various types of costs. Among the main cost items, fuel, feedstock and chemical reagents are distinguished, however, the undisputed leader is the cost of electricity, the work of the mills needed to grind the feedstock. On the other hand, the problem of timely and quick diagnosis of the internal components of the mills and the ability to choose the optimal mode of operation are also relevant tasks. These reasons significantly affect such process indicators as the quality of the crushed raw materials, the energy efficiency of the grinding process, reducing the cost of the production cycle, etc. To control the processes of grinding, loading of raw materials, monitoring the filling of the drum, the use of vibroacoustic primary transducers installed on the housing of the axle bearing of the drum mill is promising.
