Introduction of raw materials
Granite is a common type of felsic intrusive igneous rock which is granular and phantomatic in texture.,mainly consisting of feldspar, quartz. The word "granite" comes from the Latin granum, a grain, in reference to the coarse-grained structure of such a holocrystalline rock. its SiO2 content usually lies above 7o%.Granites can be predominantly white, pink, or gray in color. These rocks mainly consist of feldspar, quartz, mica, and amphibole minerals. By definition, granite is an igneous rock with at least 20% quartz and up to 65% alkali feldspar by volume.

Project Processing Process
1.Big granite materials are fed to the jaw crusher evenly and gradually by vibrating feeder through a hopper for primary crushing.

2.After first crush, the material will transferred to Impact crusher by belt conveyor for secondary crush; the crushed granite materials will then transferred to vibrating screen for separating.

3.After separating, the parts that can meet standard will be transferred away as final products, while the other parts will be returned to Impact crusher, thus forming a closed circuit.

4.Size of final products can be combined and graded according to the specific requirement.
