Use of coal as a fuel in cement plants and its impact on

 · Summary In this paper the use of coal found at Jabba Taar and Jabba Khushk Khyber Pakhtoon Khwa in cement manufacturing as a major fuel and its impacts on the raw mix and clinker parameters has been discussed. The maximum amount of coal for pulverizing with raw mix was found to be 10 `of the raw mix as calculated from the calorific value and the heat of clinkerizationof coal. The coal residue left after burning was utilized in the cement raw material for which a new raw mix was designed. The new raw mix was converted in to clinker. The resulting clinker was studied for all parameters as per British specification. It was found that the clinker obtained from the newly designed raw mix with coal
