Energy Savings Potential. Reductions in the range of 4-6 kwh/t cement are reported from India, depending upon the product type. Chinese flag In China, for 5000t/d cement production line using a ball mill with closed circuit system, power consumption index is reported to range between 38 ~ 42kWh/t (NDRC, 2008. p.48).
Ball mills account for the majority of all mills in cement plants and therefore the optimization of established ball mills implies high savings potentials. Parameters that hold potential energy savings are load level, revolution speed, combination of the ball charge, lining design and the adjustments of the separator. Standard.
High pressure roller press can be introduced as a pre-grinding step for the ball mill, in order to decrease specific power consumption in finish grinding and/or to increase the output of finish mill. Grinding capacity of finish mill increases by about 30%. Up to capacity increases are reported in India with the use of this.
