Limestone is a sedimentary rock composed largely of calcite, calcium carbonate (CaCO3). Limestone often contains variable amounts of silica or siliceous skeletal fragment, as well as varying amounts of clay, silt and sand sized terrestrial detritus carried in by rivers.

The design of a stone crushing production line is usually decided by several factors:
1) raw materials to be crushed
2) The hardness, percentage of Si, moisture percentage of the raw materials
3) The average size of the raw materials before entering into the crushing system
4)Requested product sizes, percentage of the sizes, and their usage
5) hour capacity of the crushing line
For the Limestone crushing lines, 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 + 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 Compound cone crusher(plate pressing principle).

If the local market has not request of the stone shape, users prefer to use fineness jaw crusher, or Compound 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 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 has the functions of crushing and shaping, can make very good cubic shape; the stone materials are mainly used for highway, water conservancy, airport, civil construction etc. The market prices of stones made by impact crusher is higher than that by fineness jaw crusher or compound cone crusher; the quick wear parts cost of impact crusher is also high for high hardness stones.
If the market has request for the stone shape, and the users want to reduce the quick wear parts cost. Here we recommend firstly use primary jaw crusher + fineness jaw crusher/compound cone crusher as the primary and secondary crushers, take the impact crusher as the tertiary crusher to shaping the stones. This proposal has been adopted by many users, and proved to be workable.

Most crushed stone is limestone and dolomite. It is used mostly for construction purposes, although much of it is also used in shoreline protection. In construction, crushed limestone is used as an aggregate in concrete mixes. The limestone binds the mix together when it hardens. Almost 60% of all crushed limestone is used as aggregate in highway concrete and asphalt.
Limestone crusher are used widely in limestone crushing industry. Many limestone crushing plant includes limestone crusher and limestone mill or other related limestone crushing equipments. Limestone mining has important position in modern construction and road building industry because limestone is the most widely used stone or rock. YIFAN is a professional limestone mining equipments supplier and can supply you many limestone mining machines such as limestone mining crusher, limestone mining mill, limestone mining feeder and so on.
