SOME PROBLEMS RESULTING FROM HIGH CLINKER TEMPERATURE

Apr 26, 2020Too high clinker temperature, especially above 70C, causes se-veral diffi culties in cement production, lowers its quality and leads to lumping of the material in the silos. To avoid these diffi culties the appropriate clinker granulometry trough special technological treatment, should be obtained.
