· Then the ball mill and the air classifier were modelled by using perfect mixing approach and Whiten's equation respectively. The relations between the types and dosage rates of grinding aids and model parameters were examined. The fact that such an examination has not been made previously by using industrial data, which makes this research unique. It was deduced that depending on the ...

It disperses and suspends cement raw meal powder in airflow, making fuel combustion and calcium carbonate decomposition happen in a short time (generally ~ 3 seconds). To some extent, it replaces part of the calcining work of a cement rotary kiln. In the calciner, because the fuel combustion and the material endothermic reaction are carried out at the same time, there is no visible flame ...

White cement is used primarily for architectual appliions requiring white or colored concrete. Due to a low iron content, normally less than % Fe 2 O 3, the potential liquid formation within the clinkering process for white cement is low and the burnability of the raw material is very hard. A typical silica modules for white clinker is in ...

Cement Milling. Cement milling is usually carried out using ball mills with two or more separate chambers containing different sizes of grinding media (steel balls). Grinding clinker requires a lot of energy. How easy a particular clinker is to grind ("grindability") is not always easy to predict, but large clusters of belite due to coarse silica in the feed are difficult to grind. Rapid ...
