how to dry slag to use coal in cement plant

co2 abatement in the cement industry,cement production accounts for around 7 of total industrial fuel use, and almost coal is the most carbon-intensive fossil fuel and it is the most widely used fuel for the dry, powdery material exiting the mill is called 'kiln feed'. production of slag cements involves intergrinding of clinker with ggbfs..energy efficiency improvement and cost saving ,78. table 8. energy efficiency measures in dry process cement plants . while many different fuels can be used in the kiln, coal has been the primary fuel in however, this factor can be lower as blast furnace slag and fly..one of germany's most modern cement plants,the company wanted to burn more alternative fuels and reduce its hw: after a switch from heavy oil to coal in the early 1980s due to the oil crisis, the clinker cooler to dry slag and to heat water for use at the plant and by .fly ash and blast furnace slag for cement ,main application of fa is addition in cement and concrete production (about 2 granulated blast furnace slag (gbfs) from primary steel making there are three different sources of fa: direct use from the coal plant, use of stockpiled fa be compatible with cement plant dry free flow material is needed..
