Classification
Summary
Industrial production job that calcines limestone in a high-temperature kiln to produce calcium oxide (quicklime).
Description
Limestone Calcination Workers heat limestone to high temperatures (approx. 900–1000°C) in kilns called kilns, decomposing calcium carbonate to produce calcium oxide (quicklime). The work consists of processes such as raw material loading, combustion management, discharge, cooling, and quality inspection, involving high-temperature environments and heavy object handling. The produced quicklime is widely used as construction materials and industrial raw materials. Strict temperature and calcination time management is required to maintain work efficiency and quality.
Future Outlook
Demand for construction materials and environmental improvement applications is stable, but the number of workers may gradually decrease due to automation and development of alternative materials.
