THE INFLUENCE OF DIAGENETIC AND TECTONIC PROCESSES IN DOLOMITES ON THE GRINDING
Origin and occurence of dolomites are important for the physical and mechanical properties, especially grinding. The influence of diagenetic and tectonic processes in dolomites on the grinding of rocks was investigated in samples from two diag-netically different deposit types, and that separately from the compact and tectonized part of the rock masses. The grinding tests were carried out in a ball mill. By petrographic and granulometric analysis as well as by determination of the grinding rate and Bond's Working Index it was found that the state of rock fissures influences the crushability down to grain sizes even of 1...2 mm, and that the grinding rate is lower for rocks of higher crystal lattice order and a higher content of small crystals. Also, samples with clean regular crystals, formed by recrystallization, manifest a stronger resistance to grinding (the paper is published in Croatian).
