  • Theories on Rock Cutting, Grinding and Polishing Mechanisms

    then applications on rock material have started In this part of the book, natural stone cutting, abrasion and polishing mechanisms are compiled and presented as a summary Processes of cutting, grinding and polishing natural stones are made as a result of grindingabrading mechanism developed on the use of different abrasive grains (mostly diamondFor example, hard rocks that come from blasting can be big as 1m in size, and require multiple stages of crushing and grinding In addition, if the valuable mineral is finely disseminated in the ore the grinding size can be down to 40 microns, which can be achieved by two grinding stages at leastCrushing Vs Grinding MinerallurgyIn the previous chapter, the various “laws” of comminution which have been propounded have been studied in relation to the physical process of size reduction and to the available results of experiments into the fracture of homogeneous and heterogeneous materials by impact and by slow compression In this study it is seen that no satisfactory “law” of comminution has yet been deduced Grinding Process Mineral Processing Metallurgy
