2017-6-3 Mining for granite is done manually. For drilling and channeling hand chisels and hammers are used. There are very few quarries that have mining machinery, such as compressors and drilling machines for drilling and blasting, cranes for lifting big blocks, and dampers and trucks for transport.

2 天前 Comminution, an energy-intensive process, usually begins with blasting of rock in the mining operation followed by crushing in large, heavy machines, often used in stages and in combination with screens to minimize production of particles too fine for subsequent treatment (Sidebar 3-3). Grinding is usually done in tumbling mills, wet or dry ...
