Experimental study of crushing process of the crushed
In general, crushed stone production consists of three stages: extraction of raw materials, crushing, and sorting by fractions. Crushed stone is obtained quite simply by crushing various rocks, such as gravel, boulders, and various simultaneously mined Rock and crushed stone products generally are loosened by drilling and blasting and then are loaded by power shovel or front-end loader into large haul trucks 11.19.2 Crushed Stone Processing and Pulverized
