Lime, thanks to the benefits it affords in reducing environmental impact, is utilized in the production of steel as well as a wide range of other manufacturing processes.
This substance, which is so closely related to many aspects of our daily lives, is one of the few natural resources in which Japan has long been able to maintain self- sufficiency, thus making it especially precious. Shaft kilns having a high thermal efficiency are mainly used for the calcination of coarse limestone.
In order to use the undersized limestone that cannot be calcined in such facilities, however, rotary kilns are utilized irrespective of their lower thermal efficiency. Since its founding in 1975, our company has been guided by the principle that realization of thermal efficiency in the production of undersized limestone equivalent to shaft kilns would make a substantial contribution to more efficient utilization of Japan's natural resources.
Devoting our all-out efforts to this task, we succeeded in developing the "CHISAKI KILN," equipped with a rotary hearth. The first plant was constructed for Kunneppu Lime Industry Co., Ltd. of Hokkaido. With performance that proved fully up to expectations, the new plant soon attracted inquiries that led to our construction of more than 100 plants, including shaft kilns for hard burning. In the future, we shall continue to strive to become a global enterprise with environmentally friendly products. In this regard, I shall be grateful for your encouragement and support.
