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.

Limestone crushing process

Limestone or limestone is rich in resources, and the raw ore grade can generally meet the requirements of various industrial sectors. Therefore, usually, only simple ore washing is required, and no complicated ore beneficiation process is required for purification. Limestone processing is mainly crushing, grading, and producing quicklime, slaked lime, precipitated calcium carbonate, ultrafine (nano) calcium carbonate, carbon dioxide, etc. Limestone generally adopts a dry crushing process. For limestone used in metallurgy and roads, the ore can be crushed and screened.
