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.
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.
- The manufacture of quicklime (calcium oxide) and slaked lime (calcium hydroxide);
- Cement (concrete) and mortar
- An excellent building stone for humid regions;
- Common in architecture
- Pulverized limestone is used as a soil conditioner to neutralize acidic soil conditions;
- Crushed for use as aggregate—the solid base for many roads;
- Glass making, in some circumstances;
- Added to paper, plastics, paint, tiles, and other materials as both white pigment and a cheap filler.
- Added to bread and cereals as a source of calcium
- Used in blast furnaces to extract iron from its ore
Limestone is important buiding materials, and raw materials for cement production. We must crush limestone into suitable size through limestone crushing process or grind them into sand or powder by limestone grinding machine in limestone processing plant.Limestone crushing process need limestone crusher equipment. In this process, we usually use jaw crusher, cone crusher, mobile crusher such as portable mobile crusher, crawler type mobile crusher. These machines are used to crush limestones into smaller particles. According to the different products, we choose the different crushing process. Usually limestone crushing plant includes primary crushing process and secondary crushing process.
In cement plant, limestone is the important raw material to make cement. It goes through crushing, grinding process, then make into powder.
In casting sand production line, limestone is crushed into the particles with 58 - 57 mesh. This limestone sand is better than the performance of quartz sand in manufacturing of machinery.
