Some problems resulting from high clinker temperature in cement production

Too high clinker temperature, especially above 70°C, causes several difficulties 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. In the case of insuffi cient cooling in the cooler the water spraying into the cooler or on clinker transporting devices is to be employed. Water injection into the mill as amount of ventilation air give also good results. Finally the partial substitution of gypsum by anhydrite in the mill or in silos. It is much better to install the cement coolers than to carry the consequences of high cement temperature.
