Wear impacts in slag grinding in various grinding technologies

Through the ongoing process of improving the economy of producing cement, many manufacturers are looking to additives to replace the base material of clinker. One additive that has made a significant impact is the use of slag material. This paper concentrates on the ground granulated blastfurnace slag (GGBS). Slag material has similar hydraulic properties to cement and as such has shown to be an excellent substitute for raw clinker materials. To date there have been some drawbacks utilizing slag in cement manufacturing including higher specific power consumption in the finished grinding area and increased handling and maintenance circuit wear. This paper will address these two areas and how the latest technological advances are meeting these two challenges.
