INTENSIFIER OF CEMENT CLINKER MILLING Russian patent published in 2014 - IPC C04B7/52 

FIELD: chemistry.

SUBSTANCE: invention relates to the field of construction materials, in particular to compositions of additives, used for intensification of cement clinker milling. An intensifier of cement clinker milling, containing a plasticiser of a sulphonate type based on a mixture of oligomeric products of naphthalenesuphfonic acid condensation, which includes oligomers with a number of naphthalene nuclei from 2 to 25, as the plasticiser contains a composition of oligomeric products of naphthalenesulphonic acid condensation, modified lignosulphonates-lignosulphonates, processed with triethanolamine with a ratio of components (wt %): lignosulphonates - 60-90, triethanolamine - 10-40, water-soluble silicon compound - oligomeric silanol, containing at least 1 bond of silicon with sp³-hybridised carbon and mixtures of medium salts of sulphur-containing acids with degrees of oxidation +6, +2 and -2 in a ratio of 20-30:35-40:35-40, with the following ratio of components (wt %): oligomeric products of naphthalenesulphonic acid condensation - 30-97, modified lignosulphonates - 1-50, water-soluble silicon compound - 1-10, mixture of medium salts of sulphur-containing acids - 1-10.

EFFECT: increased efficiency of clinker milling with small doses of the milling intensifier.
