Basalt, diabase, granite, limestone, river pebbles and other stones are materials with high hardness and high silicon content, which are difficult to crush or have high crushing cost in actual crushing operations. In layman's terms, basalt and diabase are hard and tough materials, granite is hard and brittle materials, and river pebble is relatively low in hardness, but has a high silicon content.  Therefore, the crushing process for these materials should be designed reasonably, and the production cost of the production line should be considered while considering the investment cost of the crushing project. In the actual crushing operation, the typical lamination equipment configuration is the process configuration of jaw crusher and cone crusher.
