The Effects of Blasting on Crushing and Grinding ...

introduced to the primary crusher will affect the feed size distributions throughout the crushing stages. The second effect of blasting, which is “unseen”, is the crack generation that occurs within fragments. There is substantial evidence that such cracking occurs. The work by Nielsen and Kristiansen (Fragblast5, 1996) is an excellent example.
