Efficient and reliable handling of GBFS and GGBFS at grinding

Granulated blast furnace slag is also extremely abrasive with wear rates some five times greater than cement clinker in comparable installations. The Aumund Group, including B&W and Schade, recognise these challenges and have developed innovative solutions for many of these handling problems with special adaptations of existing designs tailored to suit the specific demands of these new applications.

What is Slag Cement? (with pictures

Slag cement, often called ground granulated blast-furnace slag (GGBFS), is one of the most consistent cementitious materials used in concrete. It is actually a byproduct of iron production. When the iron is processed using a blast furnace, slag and iron both collect at the bottom of the furnace. The molten slag must first be separated from the

Effect of different grinding aids on property of granulated

The objective of this study was to assess the feasibility of utilization of grinding aids (GA) in the granulated blast furnace slag (GBFS) powder production. The GBFS powders were prepared with different GA, and their grindabilities, fluidities, reactivities and hydration characteristics were investigated. The experimental results indicate that although the improvement scales are various, all

What is slag cement

Slag cement is a hydraulic cement formed when granulated blast furnace slag (GGBFS) is ground to suitable fineness and is used to replace a portion of portland cement. It is a recovered industrial by-product of an iron blast furnace. Molten slag diverted from the iron blast furnace is rapidly chilled, producing glassy granules that yield

Wear protection of surfaces from high pressure grinding

When treating cement clinker as well as moist granulated blast furnace slag, wear was in the range of 0.25 grams per ton of feed or 1 Am abrasion only per operating hour - this in spite of the fact that particularly the slag has to be considered an extremely abrasive bulk solid (e.g. causing high wear rates when flowing down a chute).
