The main component of limestone is calcium carbonate (CaCO3). Lime and limestone are used in large quantities as building materials and are also important raw materials for many industries. Limestone can be directly processed into stone and fired into quicklime.
Lime has quicklime and slaked lime. The main component of quicklime is CaO, which is generally lumpy, pure white, and light gray or light yellow when it contains impurities. Quicklime absorbs moisture or adds water to become slaked lime, also called slaked lime, its main component is Ca(OH)2.
Slaked lime is formulated into lime slurry, lime paste, lime mortar, etc., which are used as coating materials and brick and tile adhesives. Some places are also called: limestone, calcite, marble, chalk, aragonite, white marble.
Limestone processing and production process
In the process of limestone production and processing, the following equipment is mainly used: pulverizer (Raymond mill or high pressure mill), jaw crusher, hammer crusher, impact crusher, sand making machine and other equipment.
The first stage
First use crusher equipment to crush the large pieces of limestone.
The second stage
After crushing, the materials with suitable particle size will be sent to YGM high pressure Raymond mill or HGM ultrafine pulverizer by conveying equipment.
The third phase
After the material enters the industrial pulverizer, it goes through the pulverization process, classification process and separation process of the pulverizing equipment to obtain the finished product. In the process of limestone production, dust removal equipment is equipped to prevent dust pollution.
The fourth stage
Packaging and storage of finished materials.
Required equipment
The main component of limestone is calcium carbonate (CaCO3). Lime and limestone are used in large quantities as building materials and are also important raw materials for many industries. Limestone can be directly processed into stone and fired into quicklime. Lime has quicklime and slaked lime. Crushing and grinding equipment is required in the limestone processing process.
