The method is not carried out, since at 1400 ° C it occurs at 1400 ° C) the clinker melts, and cooling - at lower temperatures.
Примечание: При затворении цемента, полученного на основе известного способа при 1100°С, сначала наблюдаетс ложное схватывание и цемент указаншле свойства показал после дополнительного перемешивани .Note: When mixing the cement obtained on the basis of a known method at 1100 ° C, a false setting is first observed and the cement indicated its properties after additional mixing.
При введении двуводного гипса на слой клинкера в интервале температур 1150-1350°С ввиду высокой температуры образуетс нерастворимьш. ангидрид (в известном способе - растворимый ангидрид и полуводный гипс), который в процессе помола в мельнице ввиду отсутстви воды исключает возможность перехода двуводного гипса к полуводной форме, что улучшает усшови помола цемента, способству повьшению его прочности при твердении. В процессе твердени цемента нерастворимый ангидрид кроме нормального замедлени сроков схватывани вызывает повьшениеWhen two-water gypsum is added to the clinker layer in the temperature range of 1150-1350 ° C, insoluble is formed due to the high temperature. anhydride (in the known method - soluble anhydride and semi-aquatic gypsum), which, due to the absence of water, during grinding in the mill eliminates the possibility of transition of two-water gypsum to semi-aquatic form, which improves the use of cement grinding, contributing to its hardening strength. In the process of cement hardening, insoluble anhydride, in addition to the normal delay in setting time, causes an increase in
