Grinding of limestone samples

Grinding of limestone samples

Jul 01, 1999 According to the data given in Table 1, the increase of the mixture fineness influences the clinker fineness but to a significantly lower degree. In addition, limestone content over 30% inhibits the grinding of both clinker and limestone. The samples containing 40% limestone have lower clinker and limestone fineness, compared with those

    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
