On the issue of reducing the energy of disintegration during the enrichment of ore mineral raw materials

An analysis of the existing classical theories of determining the amount of energy required for the disintegration of solid bodies is carried out. Each of them implements only a small part of the spectrum of conditions for crushing and crushing of mountain ore rocks. At the same time, they practically do not take into account the contact friction between the tool and the rock, as it happens in crushers and pipe mills. The authors proposed to use a new theory of local rock destruction taking into account internal and contact friction with symmetrical and asymmetrical distribution of contact tangential stresses. Studies show that the asymmetric distribution of contact tangential stresses theoretically provides a decrease in the specific energy of destruction of ore mineral raw materials up to 40 - 45 times.

The conference was canceled due the low number of presenters registered for the conference, but the Book of abstracts has been published.
