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.

The rock hardness of basalt is 6 as per the Mohs scale and can be observed through a combination of its compressive strength. Generally, 100-300 Mpa or Megapascal is the compressive strength. Its tensile strength is10-30 Mpa, and its shear strength is 20-60 Mpa, which denotes that depending on the mineral makeup, basalt rocks fall in the category of a strong – very strong.

JAW CRUSHER. Jaw Crushers (QJ241, QJ341, UJ440i) are excellent for use in primary applications.With various jaw plate configurations available they are ideal for use in crushing hard rock products such as granite and basalt and other material with comprehensive strength below 320MPa.

Basalt crushing line flow. The processing of basalt is divided into three stages: coarse crushing by jaw crusher, medium and fine crushing by cone crusher and sand making and shaping by sand making machine. The first stage: coarse crushing. Large basalt materials are uniformly fed by the vibrating feeder through the silo, and then transported

a crusher: type, size, eccentric throw, setting and motor size. In practice, the energy measurement according to Bond''s method is carried out with an impact-testing machine. The impact strength of a rock is an important m easure of its toughness and crushability.
