Granite is a common type of intrusive, felsic, igneous rock which is granular and phaneritic in texture. This rock consists mainly of quartz, mica, and feldspar. Granites sometimes occur in circular depressions surrounded by a range of hills, formed by the metamorphic aureole or hornfels.
Granite contains much course and medium quartz and feldspar. It the most common plutonic rock in the earth’s crust and it is formed by cooled magma deeply in the earth's crust. As can be used for paving stones and building stone, granite mining was once an important industry. On the design of the crushing process, Liming Heavy Industry selects the laminated crushing equipment in order to reduce the loss of wear parts. The typical configuration is secondary jaw crusher or jaw crusher plus cone crusher. If the clients have higher request for final products shape, the impact crusher can be used for reshaping. Thus, three stage crushing process configurations are formed. Three stages crushing will inevitably lead to a higher investment cost. But for the long-term operation stones factory, three stages crushing will be very substantial to the production cost reduction.
Granite is a kind of versatile building material. Granite has many characteristics, such as rich in resources, wide distribution and varieties. Granite is used for building houses, roads and bridges in folk traditions. Granite belongs a special ore which contains much quartz and rarely iron. The crystal combines very tight, fine texture, acid-proof, corrosion resistance and wear resistance. It is a high-quality corrosion-resistant material that can be used in chemical, metallurgy, thermal power, cement, printing, defense facilities and other fields.
