A number of phases are formed in the clinker feed before the burning zone proper is reached. These intermediate phases dissociate in the burning zone and are not therefore found in clinker but assist in forming the final clinker minerals. Sulfate melt phase At intermediate temperatures, sulfates combined with calcium and alkalis form a liquid ...

1. Introduction. Grinding aids (GAs) are a kind of additive commonly used in cement, which can effectively reduce the energy consumption of cement research and production processes [1], [2].It has been confirmed that the addition of GAs of 0.01 %–0.05 % by cement weight to ball mills can significantly increase the machine-hour output of …
The final manufacturing stage at a cement plant is the grinding of cement clinker from the kiln, mixed with 4-5% gypsum and possible additives, into the final product, cement . In a modern cement plant the total consumption of electrical energy is about 100 kWh/t . The cement grinding process accounts for approx. 40% if this energy consumption.
