Journal of the Chemical Society of Pakistan Use of coal as a

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 clinkerization of 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.
