To the question of the cement production materials destruction

The article deals with the problem of determining the energy for the cement production materials destruction. It is shown that the destruction of various materials consumes a significant amount of energy. One of the most energy-intensive building materials is cement. The method of energy calculation for the cement production materials grinding on the cement clinker example is proposed. The grinding cement clinker process and additives is described on the basis of the thermodynamic method. The assumptions are made under which the destruction of the cement clinker occurs under the influence of external forces. The change in the volume of the crushed material due to the increase in energy in the original volume is shown. The expression for the elementary work on the cement clinker particles destruction is proposed. The expression for determining the total work on grinding the particle of cement clinker depending on its size, generalized thermodynamic force and elastic modulus of the crushed material is obtained.
