The basaltic rock shows a variety of textural and mineralogical characteristics which could affect their physical and mechanical properties as well as their use as construction material. The rock material and aggregate properties of the basalts were compared with the known standard values and evaluated for their suitability for …
Basalt is a very tough rock and is difficult to break or chip. It often occurs as an extrusive rock, which means it is formed from lava that has cooled on the surface of the earth. It is a very common rock and can be found all over the world. However, it is most commonly found in areas that have a lot of volcanic activity.
The aggregate morphology is mainly governed by aggregate mineralogy, type of rock and crushing operation [8,9,10]. For given aggregate type, the associated crushing mechanism plays a decisive role in governing morphology of aggregates. ... The study uses basaltic aggregate produced from two different crushing mechanisms (i) …

The first stage: coarse crushing Large basalt materials are uniformly fed by the vibrating feeder through the silo, and then transported to the jaw crusher for coarse crushing. After the coarse crushed materials are screened by the vibrating screen, they are transported by the belt conveyor to the cone crusher for medium and fine crushing.
Minerals of the feldspathoid group occur in a large number of basaltic rocks belonging to the alkali group; nepheline, analcime, and leucite are the commonest, but haüynite is occasionally present.
