Impact Of Rock Fragmentation On Crusher

Rock Fragmentation by Blasting

Rock Fragmentation by Blasting

The fragmentation of rock is fundamental to mining. It is the first preparatory stage in the extraction process – making rock small enough and loose enough to be efficiently excavated. But this simple statement underestimates how important this activity is for the whole mining operation.
