Abstract.

The problem of grinding mineral raw materials in a ball rubber lined mill is considered. We consider the theory of Coulomb-Navier to calculate energy intensity of destruction of iron ore samples during the compression and shear deformations. It is shown that the ways and means in which the shear stresses are realized mainly are the most energy damage mechanism of iron ore.

Keywords:
