Rock Mechanics (ISRM). The Bond crushability index, uniaxial compressive strength, elasticity modulus and dry density of the rocks studied are shown in Table I. Generally, there are three Bond indices: ball, rod and crushability. The Bond ball and rod indices are determined using standard ball and rod mill, respectively, and are suitable for grinding.
