limestone crushing plant
The design of a limestone crushing production lines are usually decided by several factors:
1) raw materials being crushed
2) The hardness, percentage of Si, moisture number of the raw materials
3) The common size of the recycleables before stepping into the crushing system
4) Requested product sizes, number of the sizes, and their usage
5) hour capacity of the crushing line
Limestone Crushing and Gridning Process
For the Limestone crushing production lines: 30-50tph, 50-80tph, 80-120tph, 120-200tph, 200-300tph, 300-400tph, 400-500tph, 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 +primary jaw crusher +fineness jaw crusher +impact crusher(optional)+vibrating screen +belt conveying system +control system
Proposal 3: vibrating feeder +primary jaw crusher +Compound cone crusher +impact crusher(optional)+vibrating screen +belt conveying system +control system
Within the above proposals, the gap is the secondary crusher: using impact crusher (hammer crushing principle), or using fineness jaw crusher(plate pressing principle), or Compound cone crusher(plate pressing principle).
Crusher Machine For Limestone Powder
In the event the local market hasn’t request with the stone shape, users prefer to use fineness jaw crusher, or Compound cone crusher since the secondary crusher. Because for high hardness stones, the short wear parts cost of fineness crusher/cone crusher is gloomier compared to impact crusher.
For jaw crusher and compound cone crusher, the working principle is plate pressing, so the percentage of stones with flaky shape, internal cracks is high.
For impact crusher, it’s the functions of crushing and shaping, can make very good cubic shape; the stone materials mostly are employed for highway, water conservancy, airport, civil construction etc. The marketplace prices of stones created by impact crusher is more than that by fineness jaw crusher or compound cone crusher; the short wear parts cost of impact crusher can be high for high hardness stones.
In the event the market has request the stone shape, and the users wish to decrease the quick wear parts cost. Have a look at recommend firstly use primary jaw crusher + fineness jaw crusher/compound cone crusher because the primary and secondary crushers, take the impact crusher because the tertiary crusher to shaping the stones. This proposal may be adopted by many users, and became workable.
