Process technology for efficient and sustainable cement production
Comminution and especially cement grinding still account for the majority of the electrical energy demand of cement production. As Fig. 12 shows, between 60% and depending on cement properties up to 70% of the roughly 100–110 kWh of electrical energy per ton of cement are used for comminution processes [5], [45]. It has to be noted that …

Understanding Limestone in Cement
Because the limestone is softer than the clinker it will grind preferentially, resulting in a cement with a better particle size distribution with less energy. The limestone also requires less processing and does not undergo calcination, so it releases less waste in its production. The resulting cement will perform at least as well as cements ...
