Granite contains much course and medium quartz and feldspar. It is 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.
