PROSPECTIVE OPPORTUNITIES TO REDUCE ENERGY CONSUMPTION FOR GYPSUM BINDERS PRODUCTION

The article analyzes the technologies of gypsum binder production and selects the most effective production method. The processes of dehydration and hydration of various modifications of gypsum are researched, in which the preservation of temperature gradient allows to obtain a semi-aqueous form of calcium sulfate throughout the entire volume of the gypsum binder particle. A mathematical model of heating of a spherical particle, which was obtained by using the Fourier's method, is presented, with the help of which the optimal size of gypsum particles for firing is calculated.
