Abstract: Improving crushing and grinding equipment, the operating costs of which account for 70% of the total cost of mineral processing or the production of construction materials such as crushed stone and cement, is a pressing issue. Crushing and grinding equipment is part of the ore preparation machinery, located at the beginning of the process chain, where ensuring uninterrupted, reliable operation is particularly critical, as downtime causes significant losses. The article considers the data on the operation of crushing and grinding equipment in Russia. The percentage of wear of the crushing and grinding equipment in Russia by industry is shown. The time spent by the equipment in repair is given. It is shown that the technical diagnostics of the technical object condition remains the decisive factor in the effective operation of crushing and grinding equipment. This work is devoted to the organization of diagnostic support for crushing and grinding equipment (CGE) with the storage of all previous diagnostic results in order to provide useful and objective information representing the background (dynamics) of the development of the process of changing the technical characteristics of CGE in the past, which can be used for systematic correction of the forecast and increasing its reliability. The analysis showed the possibility of improving diagnostic methods due to: optimization of diagnostic algorithms and the use of the latest vibration diagnostic equipment. As conclusions, it is proposed to use reliably operating external and built-in diagnostic tools for collecting data from equipment checkpoints, providing objective and complete information. The results of experimental data on the assessment of the technical condition of crushing and grinding equipment at PJSC Uralasbest using vibration diagnostics hardware are presented. Recommendations are given for eliminating the detected equipment defects.
