Limestone rocks are sedimentary rocks that are made from the mineral calcite. Limestones are important stone rocks. They can be used for building materials for humid regions but are not quite as strong as sandstone and are easily weathered by acidic conditions. Limestones are the primary source of lime stone for cements or concrete. Cement is considered one of the most important construction materials ever invented by man. Limestone can be crushed and used as road ballast. Significant quantities of limestone are quarried around the world for these purposes.
If the local market has not request of the stone shape, users prefer to use fineness jaw crusher, or cone crusher as the secondary crusher. Because for high hardness stones, the quick wear parts cost of fineness jaw crusher and cone crusher is lower than that of impact crusher.
