Calcium oxide, with the chemical formula CaO, is produced by thermally decomposing limestone or shells containing calcium carbonate by heating them to above 825 degrees Celsius in a lime kiln. This process, called calcination or lime burning, releases carbon dioxide, leaving quicklime. Quicklime is unstable and unless slaked with water to form lime paste or lime mortar, it will spontaneously react with CO2 in the air as it cools, eventually converting completely back into calcium carbonate.

Application of calcium oxide

Calcium oxide has a wide range of applications in many fields due to its versatility. In the construction field, calcium oxide can be used as a building material to enhance the rapid setting effect of cement. In metallurgical processes, it acts as a flux to help melt metals. In vegetable oil processing, calcium oxide acts as a decolorizing agent to improve the quality of oil products. In addition, it can also be used for soil improvement to increase soil fertility, as a drug carrier to improve the stability and bioavailability of drugs, and as a calcium fertilizer to promote plant growth.

Calcium oxide is also used to make refractory materials to improve the high temperature resistance of materials. As a desiccant, it can absorb moisture in the air and keep items dry. In wastewater treatment, calcium oxide is used to treat acidic wastewater and sludge conditioning to purify water quality. In addition, it is also used to make chemicals such as calcium carbide, soda ash, and bleaching powder. 

Calcium oxide processing flow

The processing flow of calcium oxide mainly includes the calcination of limestone and the grinding of calcium oxide. After the limestone is crushed and screened, it is sent to the lime kiln for calcination. At a high temperature of 900 to 1200 degrees Celsius, the limestone decomposes to produce calcium oxide and carbon dioxide. After the calcined calcium oxide is cooled and crushed, the preliminary calcium oxide product can be obtained. In order to obtain finer calcium oxide powder, professional powder making equipment is required. The 200 mesh calcium oxide powder making machine plays a key role in this link. This equipment can further grind the calcium oxide particles into 200 mesh fine powder to meet various application needs.
