In this regard calculation of work index of limestone made by standard Bond grindability test. Ball mill was employed to conduct the grinding test of seven different samples. Among all seven samples collected from the different faces of quarry, Bond work index of limestone Face4A results less than 20kwh/t, remaining 6 samples are marked as hard -

Limestone is a member of the sedimentary rock family and is usually gray or black. Its chemical composition is mainly CaO, generally 45% to 55%, followed by a few of MgO, SiO 2 and Al 2 O 3.. The mineral composition of limestone rock is mainly calcite or calcareous bioclasts (such as shells or biological bones, which are also composed of calcium carbonate), followed by dolomite, clay, silt ...

A wide range of prehistoric artifacts were formed by pecking, grinding, or polishing one stone with another. Ground stone tools are usually made of basalt, rhyolite, granite, or other macrocrystalline igneous or metamorphic rocks, whose coarse structure makes them ideal for grinding other materials, including plants and other stones. Native Americans used cobbles found along streams and in ...
