    Production of Natural Stone Norges Geologiske Undersøkelse

    Natural stone must be carefully quarried and preferably removed as large blocks. The first step is to take down the "primary block", which is a large dimensioned chunk of rock loosened from the quarry wall. This is most often achieved by drilling, blasting or/or sawing. A primary block can vary in size depending on the stone type, and up to 1000 cubic metres, 2700 tons!

    Rock Crushing Rule of Thumb - Mineral Processing Metallurgy

    For an underground hard rock mine, a gyratory crusher may be more economical in the case where it’s required daily production exceeds 8,000 tonnes of ore. Source: Jack de la Vergne; If the hourly tonnage to be crushed divided by the square of the required gape in inches is less than 0.115, use a jaw crusher; otherwise use a gyratory.
