The auxiliary equipment in this machine is divided into compressive strength auxiliary equipment, tensile strength auxiliary equipment (Brazilian splitting method), and zoom shear auxiliary equipment. It should be able to conduct pressure tests on coal and rocks, as well as uniaxial compressive strength tests, Brazilian splitting tests, and shear tests.
It is capable of automatically collecting test data and calculating parameters such as uniaxial compressive strength, tensile strength, and shear strength of rocks.
● Rock strength test: The rock test is conducted by applying pressure between the upper and lower plates of a press until the specimen is crushed, and the pressure strength value is measured.
