production capacity of such plants. The total investment cost for a roller mill calcining system is lower than for longtime calcining systems, since the process steps of grinding, drying and calcining occur simultaneously (lower space requirement, smaller building dimensions, lower investment costs for the equipment). In the roller mill calcining
•Lime production is an energy intensive process characterized by high emissions of CO2. •The main energy consumption of lime production is located in the calcination process and accounts for the major percentage of the total energy consumption. •The fuel consumed during the calcination represents around 50 % of the production costs of lime.
The cost of energy as part of the total production costs in the cement industry is significant, warranting attention for energy efficiency to improve the bottom line. Historically, energy intensity has declined, although more recently energy intensity seems to have stabilized with the gains. Coal and coke are currently the primary fuels for the sector, supplanting the …
