Limestone Ore Crusher Equipment is used widely in limestone crushing industry. Many limestone crushing plants include limestone crusher and limestone mill or other related limestone crushing equipment. Limestone mining has important position in modern construction and road building industry because limestone is the most widely used stone or rock. DSMAC is a professional limestone mining equipment supplier and can supply you many limestone mining machines such as limestone mining crusher, limestone mining mill, limestone mining feeder and so on.
Limestone are important rocks. They can be used for building materials but are not quite as strong as sandstone and are easily weathered by acidic conditions. Limestone are the primary source of lime for cements. Cement is considered one of the most important construction materials ever invented by man. Limestone can be crushed and used as road ballast. Significant quantities of limestone are quarried around the world for these purposes.
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 + 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 does not require 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, and 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 shape the stones. This proposal has been adopted by many users, and proved to be workable.
