Thus, the urgency of using crushers in mining and processing plants is clear, so it is relevant to find ways to optimize their operation and reduce energy consumption. This article presents a systematic review of the task of improving the energy efficiency of crushing units.
This is achieved by studying modelling methods and results, the automation of crushing and grinding processes, and the wear reduction of crusher components. On the grounds of the reviewed sources, the main methods of increasing the efficiency of crushing units are identified. A mathematical model of the cone crusher was designed.
The amounts and proportions of crushing energy and transport energy for Tests 1–4 were 8723 J, 1356 J, 621 J, and 133 J, with energy proportions of 89.9%, 80.6%, 71.4%, and 44.2%, respectively (Fig. 5).
From the spatial distribution of coal crushing, it can be observed that the amount of crushing energy at different locations is essentially the same as the change in coal mass. As the gas pressure decreased, the amount of crushing energy at the same location approached that of the transport energy gradually.
The necessity to develop energy-efficient technologies for the mineral industry will increase in the future, considering the exhaustion of high-quality resources and severe environmental limitations. The subject of this study is crushing equipment. It is a complex of units designed to reduce the fraction of ore and non-metallic solid materials.
A significant drawback of crushing units is their low energy efficiency. A characteristic feature of the crushers is their continuous function. The desired degree of material reduction is to be maintained while the volume of the feed material is constantly controlled.
