Description
глиноземного производства - белитовый и фторгипсовый шлам. Эти компоненты с добавкой воды перемешиваютс и измельчаютс в шаровой мельнице до тонкости 1500-3000 см2/г. Экспериментальные исследовани проводились со шлемами каменных углей Кузбасса и отсевом бурых углей Канско-Ачинского бассейна. При этом приготовление смеси Осуществл лось в лабораторных услови х. .Alumina production - Belite and fluorine gypsum sludge. These components with the addition of water are mixed and ground in a ball mill to a fineness of 1500-3000 cm2 / g. Experimental studies were carried out with helmets of Kuzbass coals and screening of brown coals of the Kansk-Achinsk basin. In this case, the preparation of the mixture was carried out in laboratory conditions. .
Состав смеси и прочность образцов на одноосное сжатие представлены в таблице.The composition of the mixture and the strength of the samples under uniaxial compression are presented in the table.
Выполненные теплотехнические исследовани образцов (их сжигание) показали, что теплота сгорани затвердевшей угольной смеси снижаетс по сравнению .с исходной на 20-30% (высша теплота сгорани снижаетс до 6000 ккал/кг, низша - до 4200 ккал/кг).The performed heat engineering studies of the samples (their burning) showed that the heat of combustion of the hardened coal mixture decreases by 20-30% compared to the initial one (the higher heat of combustion decreases to 6000 kcal / kg, the lower to 4200 kcal / kg).
Т.е. смесь пригодна дл подземной газификации и идентична по своим параметрам высокозольным угл м, Those. the mixture is suitable for underground gasification and is identical in its parameters to high ash coal,
При приготовлении горючей смеси на цементной основе, дол в жущего составл ет в зависимости от горно-технологических условий 5-12%. .In the preparation of a cement-based combustible mixture, the amount of cement is 5-12% depending on the mining and technological conditions. .
