  • 10 Advantages and Disadvantages of Quarrying Limestone

    02.05.2018· If you’ve found a deposit of limestone, then what you’re really seeing are the skeletal fragments of forams, coral, and molluscs. It is about 10% of the total amount of sedimentary rock found on our planet. Quarrying limestone is the process of removing this material from the ground. As with any quarrying process, there are certain pros and cons that must be evaluated.

  • Quarrying PowerX Equipment

    When quarrying stone there may be areas in the Quarry where there is a large amount of clay contamination. These occur particularly in Limestone Quarries where the clay sediments collect in fissures in the stone. This clay slows down the Crushing and Screen process, so it is scalped off at a size (generally 80mm 100mm). This allows the clean stone to be crushed without fear of blocking. So
