Chipping and crushing mechanisms in orthogonal

2016-12-1  The rock removal mechanism in the rock cutting process includes crushing and chipping failure modes. Crushed and powdery chips are attributed to the crushing mode while chunk-like chips are formed due to the chipping mode. Chipping of rock has been concluded to be caused by either tensile or shear stresses by different researchers.

Chipping and crushing mechanisms in orthogonal

2016-12-1  A rock crushing zone, i.e., the red and shaded area in Fig. 2, namely a Tip Crushing Zone (TCZ) is assumed to be formed beneath the cutter's rake face and close to the cutting edge. Since the TCZ is formed due to the crushing of rock, the TCZ boundary is assumed as an arc with a uniform stress distribution equal to the rock's uniaxial ...

Evaluation of size reduction process for rock

2020-6-4  The size reduction process of rocks in cone crushers is one of the most important issues, particularly for the secondary and tertiary stages of crushing operations. In this study, 17 different rock types were considered for the evaluation of their size reduction variations that occurred in a laboratory-scale cone crusher. Based on several mineralogical, physico-mechanical, and aggregate ...

ASTM D7012 - 14e1 Standard Test Methods for

Deformation and strength of rock are known to be functions of confining pressure. Method A, triaxial compression test, is commonly used to simulate the stress conditions under which most underground rock masses exist. The elastic constants (Methods B and D) are used to calculate the stress and deformation in rock structures.
