Abstract

In modern conditions, the effectiveness of traditional methods of ore preparation is reduced, due to a number of circumstances, namely high costs per unit of final products, low productivity of grinding equipment, gigantism of structures, high consumption of metal for lining material and grinding media, losses of recoverable products due to their diffusion destroying their bodies, and uncontrollability of the process of destruction of rock particles. At present, crushers are being created and tested that allow combining the functions of crushing and grinding. However, the widespread use of such crushers is limited by the relatively high energy intensity of the process implemented in them. At the Department of Mining Machines and complexes of the Ural State Mining University, experimental and theoretical studies of the processes of fragmentation are carried out. Particular attention is paid to the study of the properties of the crushability of rocks and the formation of energy consumption during crushing.
