CLINKER GRINDING IN CEMENT PRODUCTION

Clinker grindability is determined by quantity of electricity consumed for grinding (kW / ton) under other equal conditions. In cement production entire crushing and grinding process consumes about 85% of the electricity. At the same time 75% of electricity consumed for milling and only 2-20% of them consumed for grinding. According to some hypotheses, only a thousandth blow of the ball is ...

The relationship between grinding energy requirement and free lime content of the clinker is logarithmic, where energy increases with increasing free lime content. 4. Grinding energy is related with SM and L p contents of the clinkers by second-order polynomial equations. For the general range of SM (1.9-3.2), energy requirement can be accepted to increase linearly with increasing SM, for ...

Mineral Planning Factsheet Cement

most of the silica and alumina. Cement is produced by firing a carefully controlled mixture of limestone and clayey raw material at sufficiently high temperatures to produce cement clinker. The finished cement is produced by finely grinding together about 95% cement clinker and 5% gypsum/anhydrite; the latter helps to retard the setting time of the cement. This factsheet considers the ...

Effect of Free silica/Quartz silica in Kilnfeed - Page 1 of 2

If the quartz particle is large enough a wall of C2S forms around the remaining quartz, isolating it from surrounding CaO. ie the reaction SiO2 + 2CaO -> C2S becomes stalled at this point and, no matter how hard the clinker is burned, this free silica can never all react in time. This leaves two equivalents of unreacted CaO lime behind which increases the free lime of the clinker.
