Limestone, a common sedimentary rock primarily composed of calcium carbonate (CaCO3), is often white or grey but can also exhibit hues of yellow, brown, or other variations. It typically features a uniform structure or may contain fossils and boasts a relatively low hardness, usually ranking between 3 to 4 on the Mohs scale. Limestone readily dissolves in acids, producing gas release and dissolution reactions upon exposure to acidic substances.

Extensively utilized across various industries, limestone serves diverse purposes. It constitutes a fundamental component in the construction sector for cement and concrete production and finds application in metallurgical industries for iron and steel furnace processing. Additionally, in environmental preservation, limestone plays a pivotal role in flue gas desulfurization to reduce environmental pollution. In agriculture, it acts as a soil amendment agent, regulating soil pH levels. The chemical versatility of limestone extends to the chemical, pharmaceutical, and food industries, serving as a raw material for producing calcium-based products and other chemical compounds. Its versatile chemical properties render limestone indispensable in multiple domains, ranging from construction and environmental remediation to agricultural applications.

Usually a limestone crushing and screening production line is as following: the blasted big limestone rock are fed to the vibrating feeder, the vibrating feeder send limestone evenly to jaw crusher, jaw crusher is the primary crusher which can crush limestone to about 100-200mm size, then discharged material are delivered to impact crusher for secondary crushing, impact crusher can crush limestone to the demanded size, then using vibrating screen to screen out different required size for the next use. The final products can be used as building material, road material and other usage.
