limestone grinding energy consumption

EFFECT OF GRINDING METHOD ON ENERGY CONSUMPTION

use of CEM II limestone cements increased from 15% in 1999 to 31.4% in 2004 and has become the single largest type of cement produced [6]. In the conventional process of cement production, 30–80 kWh/t specific energy is consumed in cement grinding which equals 30% of the total energy consumption. Furthermore, approximately 60–70%
