[PDF] Cement grinding optimisation | Semantic Scholar

Abstract The current world consumption of cement is about billion tonnes per annum and it is increasing at about 1% per annum. The electrical energy consumed in cement production is approximately 110 kWh/tonne, and around 40% of this energy is consumed for clinker grinding. There is potential to optimise conventional cement clinker grinding circuits and in the last decade significant ...

Cement grinding Vertical roller mills versus ball mills

Cement grinding Vertical roller mills versus ball mills

today is the most used mill for cement grinding. Over the last three decades the vertical roller mill has become the preferred mill for grinding of raw materials. The grinding efficiency of the vertical roller mill combined with an ability to dry, grind and classify within a single unit gives the vertical roller mill a decided advantage over a ball mill system. However, despite these benefits ...
