Abstract

One of main lime products is quicklime (CaO) produced by the calcination of limestone (CaCO₃). In recent years, high-quality lime products are required, and the further control of product's specifications is necessary. However, the conventional calcination method of limestone has used a large-scale kiln, which is unsuitable for the calcination of fine granular limestone. Therefore, in this study, the calcination method of limestone by using a near-infrared laser was experimentally investigated to develop high-quality calcination process of fine granular limestone. This study revealed that the laser scanning of near-infrared CW laser can produce the area of quicklime on the surface of fine granular limestone.
