Slag disintegration selectivity

The article considers experimental research findings on the phase composition of ferrous and nonferrous metal industry slag as well as the morphological structure and physico-mechanical properties of individual phases of slag with the aim to evaluate selectivity of their unlocking along intergrowth boundaries in impact crushing machines. The authors validate disintegration selectivity criterion of slag treatment in centrifugal impact crushers expressed as the ratio of micro-hardnesses of the slag phases.
