Blast furnace slag has achieved a production balance in industrially developed countries. The utilization route is 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 and slag, after long-term investigation and comparison, POSCO finally chose to cooperate with our company to build a slag production line with an annual output of 300,000 tons to solve the problem of comprehensive utilization of blast furnace slag and slag.

Project Name: 300,000 tons of slag production line with an annual output of Pohang, South Korea

Host equipment: GRMS33.31 slag vertical mill

Production: 50-52t/h

Specific surface area: 4200cm2/g

The project is running well and the indicators are normal, fully meeting the customer's production requirements. The slag powder after grinding will be used as ceramsite modified soil to improve the yield and quality of crops, and on the other hand will be sold as cement additives. 

Taking the protection of the ecological environment as the starting point, CHAENG aims to develop circular economy, adhering to the ecological civilization concept of “respecting nature, adapting to nature and protecting nature”, and following the construction concept of “reliable production, advanced technology, saving investment and improving efficiency”.
