| Реферат: | eng: Under analysis is low efficiency of drum mills when dissociating higher strength aggregates of rebellious ore. It is shown that the main reason is insufficient destructive force. The structural–chemical characteristics of mineral aggregates and the role of defects in their dissociation are described. The author evaluates principles of estimating required energy input to dissociate aggregates composed of minerals with different types and values of interatomic and intermolecular bonds under high-power and high-velocity free impacts in disintegrators. By way of example, velocities of collision between minerals and disintegrator tools in dissociation of aggregates of sulfide and rare-metal ores and coal are given. © 2016, Pleiades Publishing, Ltd.
