Impact Crushers – VSIs and HSIs. Impact-style crushers include VSIs, as well as horizontal shaft impactors (HSIs), and are best used with less abrasive rock types, like limestone. These types of machines break apart material by the impacting forces of certain wear parts known as blow bars and impact plates or toggles.. Some operations also use impact-style crushers after they have already ...

Sep 02, 2019· The higher the compressive strength of rock, the higher also is its quality, which plays an important role particularly in road construction. A material's compressive strength is delineated into hard, medium-hard or soft rock, which also determines the crushing techniques used for processing to obtain the desired particle sizes.

How to Choose the Right Mortar Mix Type: N, O, S, or M

The tensile strength of rock is defined as the pulling force, required to rupture a rock sample, divided by the sample's cross-sectional area. The tensile strength of rock is very small and is of the order of 0.1 times the compressive strength. Thus, a rock material is more likely to fail in tension than in compression.

5.2 Method C, uniaxial compressive strength of rock is used in many design formulas and is sometimes used as an index property to select the appropriate excavation technique. 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.

compressive strength is then defined as the maximum load applied to crush the specimen divided by the cross-sectional area. Rock strength has been found to be size dependent because of the cracks and fissures that are often present in the material. This is illustrated from the results of tests on three rock types in Fig. 8.2.
