CEMENT SikaGrind® FOR VERTICAL ROLLER MILLS

́ Slag requires 30-50% more grinding energy than clinker to achieve the same fineness ́ Slag needs a higher fineness to reach similar early strength as Portland Cement ́ The microstructure of slag is very abrasive which causes high wear of the mill ́ GBFS typically has a high moisture content (up to 15%) when delivered to the cement plantGrinding of cement clinker in vertical roller mills is a technology introduced by LOESCHE which was first used in 1935. Almost 30 years ago LOESCHE introduced the first vertical roller mill to grind both, cement clinker and granulated blast furnace slag, in one process. The concept of M- and S-rollers was established in 1992, which is one ofCement & Blast Furnace Slag Loesche

Comparison of Grinding Characteristics of Converter Steel Slag

The converter steel slag cannot be widely used in building materials for its poor grindability. In this paper, the grinding characteristics of untreated and pretreated (i.e., magnetic separation) steel slag were compared. Additionally, the grinding property of pretreated steel slag was also studied after adding grinding aids. The results show that The vertical roller mill has the obvious advantages of a high yield and low power consumption and is primarily used in large-scale slag grinding lines [32]. However, the relationships among the type of grinding equipment, the product fineness and the application quality have yet to be systematically studied, which affects the accuracy of a ScienceDirect Study on the particle morphology, powder
