Limestone Mining
LimestoneLimestone 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.
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. All crushed limestone in Michigan is mined in open quarries. Drilling and blasting are necessary.
1. The manufacture of quicklime (calcium oxide) and slaked lime (calcium hydroxide).
2. Cement (concrete) and mortar.
3. An excellent building stone for humid regions.
4. Common in architecture.
5. Pulverized limestone is used as a soil conditioner to neutralize acidic soil conditions.
6. Crushed for use as aggregate—the solid base for many roads.
7. Glass making, in some circumstances.
8. Added to paper, plastics, paint, tiles, and other materials as both white pigment and a cheap filler.
9. Toothpaste.
10. Added to bread and cereals as a source of calcium.
11. Used in blast furnaces to extract iron from its ore.
12. Medicines.
13. Cosmetics
14. Art (sculptures)

Limestone Mining Equipment
Limestone mining equipments 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. Shanghai Jianye 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.
Shanghai Jianye crusher and grinding mill in processing limestone.
There are two processes from the raw limestone to final product-crushing process and grinding process.
If the raw limestone is bigger than the input size of your grinding mill, it should be crushed firstly. The proposed limestone crusher is Jianye impact crusher, which features reasonable structure, high productivity, easy operation and maintenance and safe performance. It can crush the material whose pressure resistance strength is under 350Mpa. The limestone from the mines is conveyed to the crusher through conveyor. Crusher reduces the size of the limestone from 1m to –25 mm size. The crushed limestone will be sent by a belt conveyer to vibrating screen becoming final products or to grinding mill to fine grind. In order to control the emissions from the crusher, a suitable bag filter system will be provided.
If the raw limestone is small enough and can be directly grinded by grinding mill, it can be grinded directly. The proposed limestone grinding mill is Jianye YGM series high pressure grinding mill (Raymond mill). If you need high fineness, you can choose micro powder mill, which features high capacity, low consumption, high fineness, flexible adjustment and trustworthy security.

Shanghai Jianye Supply: Grinding Mill, Micro-Powder Mill, Jaw Crusher, Impact Crusher, Cone Crusher, VSI Crusher, Sand Making Machine, Sand Washer, Vibrating Feeder, Vibrating Screen, Belt Conveyor.
