problem. The behavior of individual garnet abrasives in the AWJ process depends
on the geological origin of the garnets, which also affects all the material
characteristics of the garnet recyclate. The parameters of the BARTON HPX80 and
GMA 80 abrasive inputs and their recycled products were compared: mineralogical
type, apparent density, granularity, grain shape and mineralogical purity,
microhardness data and the degree of damage to the garnet grains. All individual
parameters of abrasives and their recyclates are reflected in the index of cutting
efficiency of abrasive. The effect of abrasive material properties on cuttability of
abrasives is synergistic. The new parameters in the evaluation of abrasives are
micro-hardness (brittleness criterion), specific surface and pore size distribution
(internal grain damage criterion).Workplace Institute of Geonics Contact Lucie Gurková, lucie.gurkova@ugn.cas.cz, Tel.: 596 979 354 Year of Publishing 2018
