The technology of magnesia binders (caustic dolomite) of dolomite powder [ Mg Са ( СО 3 ) 2 ]. It is shown that the lack of a temperature difference between inner and outer layers of the powder particles while avoiding decomposition of СаСО 3 on the surface of the particles. We propose a rapid method for assessing the degree of decomposition Mg С O 3 dolomite. The essence of the method is to determine the degree of calcination of raw materials and products of only one value of the mass of the calcine. All necessary calculations are performed in EXCEL as two standard tables (material balance firing of dolomite and composition of the products). In industrial environments the proposed method will allow for the continuous monitoring of the roasting process and adjust the degree of decomposition Mg С O 3 in the desired range.
