Abstract

First in the paper the results of the magnetic ceparathion of the products of the wear of the rock-сutting element from composite diamond-bearing material  from NiSn (6%) and diamonds of the brand AS 300T of 400/315 microns at destruction of the sand stone of the Torez deposit. Determination of the chemical composition and morphometric characteristics of the products of the magnetic separation of sludge, allowed to analyze the shape of the particles of deterioration of the matrix material of the   tool and the particles of the products of  destruction of the rock, which testifies about the joint fragile mechanism of their breaking off from the mass of a solid.
