DSMAC will provide you with limestone crushing process equipments as well as optimized crushing process design.
Limestone has numerous uses, including as building material, as aggregate to form the base of roads, as white pigment or filler in products such as toothpaste or paints, and as a chemical feedstock. However, it is a very heavy material, making it impractical for tall buildings, and relatively expensive as a building material.
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:
vibrating feeder +primary jaw crusher +impact crusher +vibrating screen +belt conveying system +control system
vibrating feeder +primary jaw crusher +fineness jaw crusher +impact crusher (optional) + vibrating screen +belt conveying system +control system
vibrating feeder +primary jaw crusher + 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).
The design of a limestone crushing production lines is 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 recyclables before stepping into the crushing system
4) Requested product sizes, number of the sizes, and their usage
5) hour capacity of the Crushing Plant
Limestone crushing process should be designed according to the physical properties and input size of limestone material, the maximum feeding size and processing capacities of crushing machines, and the selected limestone processing equipments.
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.
We warmly welcome you to come to inspect our factory, and we would like to design the most suitable proposal as per your requests.
