Abstract: On the basis of experiments, the technology of improving the process measures of Maerz kiln was developed according to the characteristics of low-strength and easy-to-crack of local limestone in Democratic Republic of the Congo, which achieved good results and successfully calcined quicklime. Suggestions for optimization were also proposed for the existing problems. This technical solution can provide the industry peers with reference for producing quicklime and improving efficiency and quality.

Key words: Maerz kiln, Limestone, Low-strength, Easy-to-crack, Optimization
