Cement manufacturing components of a cement plant

Cement is typically made from limestone and clay or shale. These raw materials are extracted from the quarry crushed to a very fine powder and then blended in the correct proportions. This blended raw material is called the 'raw feed' or 'kiln feed' and is heated in a rotary kiln where it reaches a temperature of about 1400 C to 1500 C.

Mar 09, 2014 When the raw mix is piled up inside a standard rotary kiln, the rate of reaction is limited by the rate at which heat can be transferred into a large mass of particles. To make this process more efficient, suspension preheaters are used in modern cement plants to replace the cooler upper end of the rotary kiln.

n=0.25 is the maximum substitution, corresponding to a Na 2 O content of 5.7%. The often-quoted compound NaCa 4 Al 3 O 9 (n=0.33, Na 2 O 7.6%) and its potassium analogue are mythical. However the tricalcium aluminate in cement always contains many other elements. In particular, substitution of silicon in the aluminate structure allows more cations to be accommodated, and for the isomorphs in ...
