ball mills are used in finish grinding. In the ball mills, the clinker and gypsum are fed into one end of a horizontal cylinder and cement exits from the other end. Modern ball mills may use between 32 and 37 kWh/ton of electrical energy (Worrell et al., 2013). The power consumption of a ball mill rated MW
