FIELD: manufacture of building materials, particular, production of binding agents based on mineral substances. SUBSTANCE: method for production of binding agent consists in dry grinding of initial oxide material, subsequent comminution of powder in the presence of dispersion medium and mixing of obtained product with dry ground material. Dry grinding is carried out to obtain 90% of powder with particles sizing leas than or equal to 30 mcm. Directed for subsequent comminution in the presence of dispersion medium is 1.0-15.0 mas. % of powder. It is comminuted to obtain 85 mas.% of the material with particles sizing less than or equal to 0.05 mcm and mixed with remaining powder of dry grinding. EFFECT: reduced power intensity of the production process of binding agent and improved its quality. 1 tbl

Изобретение относится к промышленности строительных материалов, в частности к получению вяжущих на основе минеральных веществ. Способ получения вяжущего состоит в сухом измельчении исходного оксидного материала, последующем измельчении порошка в присутствии дисперсионной среды и перемешивании полученного продукта с сухим измельченным материалом. Сухое измельчение ведут до получения порошка крупностью 90 мас.%≅ 30 мкм. На последующее измельчение в присутствии дисперсионной среды направляют 1,0 - 15,0 мас.% порошка. Его измельчают до крупности 85 мас.% ≅ 0,05 мкм и перемешивают с оставшимся порошком сухого измельчения. Достигаемый технический результат - снижение энергоемкости технологии производства вяжущего и повышение его качества.The invention relates to the construction materials industry, in particular to the production of binders based on mineral substances. A method of obtaining a binder consists in dry grinding the starting oxide material, subsequent grinding of the powder in the presence of a dispersion medium and mixing the resulting product with dry powdered material. Dry grinding is carried out to obtain a powder with a particle size of 90 wt.% ≅ 30 μm. For subsequent grinding in the presence of a dispersion medium direct 1.0 to 15.0 wt.% Powder. It is crushed to a particle size of 85 wt.% ≅ 0.05 μm and mixed with the remaining dry powder. Achievable technical result - reducing the energy intensity of binder production technology and improving its quality.
