Ground granulated blast-furnace slag plant (GGBS Plant) of Korea POSCO Process highlights
Blast furnace slag has achieved a discharge-use balance in industrially developed countries, mainly used as a raw material for slag cement and production of agricultural fertilizer. In order to solve the problem of comprehensive utilization of blast furnace slag, after long-term investigation, POSCO finally chose to cooperate with our company CHAENG to build the 300,000t/y Ground granulated blast-furnace slag plant ( GGBS Plant ).
The finished slag micro-powder will be used as ceramsite to improve soil, so as to increase the yield and quality of crops, and also will be sold as the cement additive.
