After cooling, the clinker may be stored temporarily in a clinker store, or it may pass directly to the cement mill. The cement mill grinds the clinker to a fine powder. A small amount of gypsum - a form of calcium sulfate - is normally ground up with the clinker. The gypsum controls the setting properties of the cement when water is added.

Manufacturing - the cement kiln. Most Portland cement is made in a rotary kiln. Basically, this is a long cylinder rotating about its axis once every minute or two. The axis is inclined at a slight angle, the end with the burner being lower. The rotation causes the raw meal to gradually pass along from where it enters at the cool end, to the ...

The situation of each vertical mill is different, and it must be reasonably controlled according to circumstances. Try to increase the ventilation before stopping the machine to make the fine powder into the reservoir as much as possible. If the fine powder is excessively rolled, the vibration of the mill is large.

Heat taken away by ventilation systems can accounts for roughly 20% of the total heat discharged by the ball mill. Improving that ventilation system brings more cool air into the inside of the ball bill, gradually reducing the internal temperature. However, the major benefit of using ball mills is the product fineness they can deliver.

As you can see, 51 kg/h of coal are needed, in this case. This is equivalent to an heat consumtion of 2.05GJ/tWaterVapor. This is rather low and it is explained by the heat generated by the mill itself. The sensible heat from the hot gases represent a power of 367 kW, which is slightly lower than the power of the mill.
