  • THE BOND WORK INDEX OF LIMESTONE AND ANDESITE

    Tavares and Kallemback (2013) on sam-ples of limestone, basalt and copper ore and their mixtures in different mass portions were determined the Bond work index value by the standard Bond’s procedure. They found that the energy required for grinding is most often lower when the components mixture grinded separately regarding to the required energy for grinding components together as a mixture.
