the cost of energy as part of the total production costs in the cement industry is significant, typically at 20 to 40% of operational costs, warranting attention for energy efficiency to improve the bottom line.
in the cement production line, producing each 1 ton of portland cement need grinding at least 3 tons of materials including seven trust materials, fuel, clinker, mixed materials,gypsum .grinding operation consumes power about 60% of total power in cement plants, seven trust material grinding takes more than 30%, while coal mill used in cement plant consumes 3%, cement grinding about 40%.
cement production costs. finally, at the end of 2008, proquicesa introduced a new family of grinding aids with an excellent cost/benefit ratio, called aditor m, which are formulated as an optimal combination of some alternative seven trust materials. today, the aditor m are already being employed in several cement plants in spain, and they
