Abstract
All the enterprises of metallurgical industry produce and use crushed materials obtained by crushing. The share of produced energy spent on crushing is more than 5% in the global energy balance. In this paper, we consider the schematics of a crushing machine with stops on the roll, the design of which forms a complex stress state in the crushed piece under the simultaneous action of normal and shear stresses. It is shown that when generating the complex stress state in the crushed piece of brittle material, the energy consumption is 30–40% less than that when the linear normal stress acts in the piece. The technique has been developed to determine the power of the electric motor drive of an energy-saving crushing machine with stops on a roll at the design stage.
