3. Pre-grinding slag powder mill. According to the proposed ground granulated blast furnace slag in the project, considering the project total investment cost, energy consumption in production, product quality, production cost, operation difficulty and many other factors, using roller mill grinding system is suitable for the terminal.

The production process of ground granulated blast furnace slag (GGBS) aims to produce products of the best grade and the highest yields. However, grade and yields are two competing objectives which can not be optimized at the same time by one single solution. Meanwhile, the production process is a multivariable strong coupling complicated nonlinear …

The terms blast furnace slag (BFS) and granulated blast furnace slag, as well as LD slag and electric furnace slag are used for finer distinctions. With high-quality iron ore grades with an iron content of 64 to 67 %, a blast furnace typically produces about 0.25 to 0.30 t …

Granulated Blast Furnace Slag (GBFS) contains a high level of moisture, it is hard to grind and very abrasive. 2 Natural pozzolans may not be as hard to grind as GBFS but may contain high moisture levels and be abrasive. 2 Both of these materials require grinding systems designed to deal with high moisture, hardness and abrasiveness. GBFS can be utilized in the cement …
