May 08, 2020· The Advantages of Using Dolomite Brick in Cement Kilns are as follows: (1) Excellent kiln skin performance. Because the dolomite brick is under high temperature, the cement clinker in the liquid phase will cause the surface layer of the brick body to be eroded. When the temperature rises to 1450 ° C, f-CaO in dolomite bricks will react with ...
Cement kiln dust (CKD) is an industrial waste material collected from cement kiln exhaust gases during Portland cement production. In the production of Portland cement, clay and calcium carbonate are finely ground, mixed and calcined at 1450 °C. During this process, calcium silicate is the main product formed and a dust named CKD is generated.

Cement mill Wikipedia. A cement mill is the equipment used to grind the hard, nodular clinker from the cement kiln into the fine grey powder that is cement. Most cement is currently ground in ball mills and also vertical roller mills . Large balls are used at the inlet, to crush clinker nodules (which can be over 25 mm in diameter).
Consequently, the temperature of the cement raw materials becomes a factor of great importance for heating the fuel particles. Combustion of different alternative fuels has been investigated experimentally in a pilot-scale rotary furnace under conditions similar to those in the material inlet end of cement rotary kilns.
Disadvantages: the heat consumption of the wet process is too high, usually between 5234-6490 J/kg and the consumption of ball mill vulnerable parts is also large. Compared with other processing methods, the clinker manufactured by the wet process has a low temperature when it comes out of the kiln, so this method is not suitable to produce the ...
