The slag grinding plant(GGBS plant) is a production line that processes slag raw materials through a series of process steps to obtain slag powder products that meet the requirements. Slag powder is widely used in cement manufacturing, concrete preparation, building materials and other fields. For example, slag materials can be applied to cement manufacturing plants. The processed slag material can be filled in cement to process slag cement, which can improve the performance of cement, reduce cost, and increase the benefit of the whole cement plant.
