Nature of Rock Fragmentation Process in Crushing

Understanding fragmentation behaviour of rock under crushing process is fundamental to improved productivity and efficiency in mining operations This is particularly so as all subsequent size reduction processes such as crushing and grinding are far more energy intensive than the initial blasting process employed in breaking of in situ rock

Friction of rocks SpringerLink

Experimental results in the published literature show that at low normal stress the shear stress required to slide one rock over another varies widely between experiments This is because at low stress rock friction is strongly dependent on surface roughness At high normal stress that effect is diminished and the friction is nearly independent of rock type
