Vertical Roller Mills LNV TECHNOLOGY
Vertical Slag Mill: A vertical slag mill is used for grinding and drying water quenched slag that is generated by blast furnaces into an active material which is then added to the finished cement. Note: Feed moisture <20%, feed size <10mm, final product moisture≤0.5%, final product fineness <4200cm2/g～5000cm2/g, power consumption <33 kWh/t.In this study, a typical vertical roller mill was considered as it enables the addition of significant amounts of minerals and it is identified as the most efficient technology, being characterized by an electricity consumption of ~7–8 kWh per tonne of treated material (Madlool et al., 2011; Cement Sustainability Initiative, 2017), much lowerFrontiers Evaluating the Carbon Footprint of Cement Plants
