Granite is a common type of felsic intrusive igneous rock which is granular and phaneritic in texture. These rocks mainly consist of feldspar, quartz, mica, and amphibole minerals.These form interlocking somewhat equigranular matrix of feldspar and quartz with scattered darker biotite mica and amphibole (often hornblende) peppering the lighter color minerals.
Granite is widely used for building, road and bridge construction, and also used for chemical, metallurgy, electric power, printing and dyeing, national defense installation fields etc.
If the customer requirements for the size and the shape of the finished stone are not high, you can use the two-stage jaw broken solution for production. This configuration is the lowest investment, simplest maintenance and most economic solutions of all. But disadvantages of this scheme are that the shape and size of stone is not good and the ratio of needle flake material is high. Though the granite hardness is high , but has certain brittleness. If the client price is competitive, then you can choose the two-stage broken scheme. For a long-term production, three-stages broken scheme is can effectively reduce the production cost. Add a laminating crusher between jaw crusher and impact crusher, such as PEX jaw crusher and cone crusher. This scheme can make the main crushing work be done by the primary and secondary crusher, and finally the impact crusher do the integer broken. This scheme can greatly reduce the return material after screening. Specific process configuration need be made according to the specific analysis of the actual situation, welcome to visit and communicate.
