energy balance of cement process


Energy balance and cogeneration for a cement plant ... The energy costs account for about 26% of the manufacturing cost of cement. In terms of the primary energy usage about 25% of the input energy is electricity while 75% is thermal energy. The specific energy consumption varies from about 3.40 GJ/t for the dry process to about 5.29 GJ/t for the wet process.
