Limestone properties
The main component of limestone is calcium carbonate (CaCO3), with a hardness of 3 on the Mohs scale. After limestone is mined from limestone, it is crushed to form limestone particles, namely stone, sand, or further pulverized to form limestone powder, which is widely used in building materials, highways, metallurgy, the chemical industry, and other industries. Lime is divided into quicklime and slaked lime. After being calcined, limestone turns into calcium oxide CaO (known as quicklime), generally in the form of lumps, and is used in water quality treatment, asphalt improvement, desulfurization, building materials, medicine, and other industries. Quicklime becomes slaked lime when it absorbs moisture or adds water. The main component is calcium hydroxide Ca(OH)2, used in environmental protection, medicine, food, and other industries.
| Fineness | Application Scenario | recommended equipment |
| 40-150 mesh | Mainly used in chemical products such as construction, interior and exterior wall coatings, chemical raw material filling, weighting, paper making, sealants, etc. | MTW Grinding Mill |
| 150-200 mesh | This is generally limestone with very low calcium content. Used in highway asphalt mixing plants. | |
| 250-325 mesh | Power plant desulfurization. Two standards, one is 250 mesh sieve 90, the other is 325 mesh sieve 90, and this kind of limestone has a high calcium content, the CaO content is more than 50%, and the CaCO3 content is more than 90%. | Vertical roller mill |
