The article presents a method for calculating the composition of a two-component raw material mixture for producing lime-clay cement based on fuel-containing technogenic waste - gravitational waste of coal enrichment. A method for determining the optimal ratio of components in the charge, taking into account the calorific properties of the waste, is given. The key parameter, in this case, is the energy efficiency ratio. The purpose of the calculation is to determine the ratio of components in the charge, which ensures maximum economy of process fuel. The results indicate the possibility of complete elimination of process fuel from the production cycle at the steady-state thermal process through the use of coal preparation waste.
