Description:
Granite Crushing Line
The design of a stone crushing production line is usually decided by several factors:
1raw materials to be crushed
2The hardness, Si percentage,moisture percentage of the raw materials
3The average size of the raw materials before entering into the crushing system
4Request product size,percentage of the sizes,and their usage
5Hour capacity of the crushing line
For the granite crushing production lines:
80-100tph,150-180tph,we here recommend three proposals:
Proposal 1: vibrating feeder+primary jaw crusher+impact crusher+vibrating screen+belt conveying system+control system
Proposal 2:vibrating feeder+primacy jaw crusher+fineness jaw crusher+impact crusher(optional)+vibrating screen+belt conveying system+control system
Proposal 3:vibrating feeder+primacy jaw crusher+symons cone crusher+impact crusher(optional)+vibrating screen+belt conveying system+control system
In the above proposals, the main difference is the secondary crusher: using impact crusher(hammer crushing principle), or using fineness jaw crusher(plate pressing principle), or Symons spring cone crusher(plate pressing principle).
If the local market has not request of the stone shape,users prefer to use fineness jaw crusher,or Symons spring cone crusher as the secondary crusher. Because for high hardness stones,the quick wear parts cost of fineness crusher/cone crusher is lower than that of impact crusher.
For jaw crusher and spring cone crusher, the working principle is plate pressing ,so the percentage of stones with flaky shape,internal cracks is high.
For impact crusher, it has the functions of crushing and shaping,can make very good cubic shape the stone materials are mainly used for highway, water conservancy, airprot,civil construction etc. The market prices of stone made by impact crusher is higher than that by fineness jaw crusher or spring cone crusher; the quick wear parts cost of impact crusher is also high for high hardness stones.
