THE SHORE HARDNESS OF ROCK. The shore hardness (sh) of a specimen is determined from the rebound height of a diamond or tungsten-carbide tipped hammer released from rest on to a horizontal smooth surface. The arithmetic mean of at least 20 readings taken at random on a ground surface of the rock sample is usually taken. ... TRT Terms: Crushers ...

Rock hardness refers to the resistance of a rock to scratching. Its value equals the uniaxial compressive strength (MPa) of the rock divided by 10. Rock hardness and compressive strength have a certain connection, but also have big differences. Rock hardness is the resistance of a part of the rock surface when it is pressed in…
