Cement Manufacturing Process. Cement is a material which is used to bind other materials together. Binding means it has an effect of gluing the substances together due to cohesive and adhesive action and then hardens and sets in order to become permanent. Cement is usually not used on its own; it is mixed with other materials called aggregates ...

19. (6) LOW HEAT CEMENT: • Low percentage of tri-calcium aluminates (C3A) and silicate (C3S) and high %age of di-calcium silicate (C2S) to keep heat generation low. • Very slow rate of developing strength as rate of …
In the manufacturing of cement, the following three important and distinct operationsoccur: 1. Mixing of Raw materials. 2. Burning 3. Grinding The process, by which cement is manufactured, depends upon the technique adopted in the mixing of raw materials. Therefore, on the basis of mixing the raw materials, th…
9. The burning process is carried out in the rotary kiln while the raw materials are rotated at 1-2rpm at its longitudinal axis. The rotary kiln is made up of steel tubes having the diameter of 2.5-3.0 meter and the length differs from 90-120meter. The inner side of the kiln is lined with refractory bricks. The kiln is supported on the columns of masonry or concrete and …

Cyclone preheaters are also called suspension preheaters. In the new dry process of cement manufacturing, the raw meal must be preheated in the preheater before entering the rotary kiln for calcining.The quality of the preheater in a cement plant directly affects the stability of calcining temperature and cement clinker quality in the kiln.
5 CEMENT –HISTORY In India, Portland cement was first manufactured in 1904 near Madras, by the South India Industrial Ltd.But this venture failed. Between 1912 and 1913, the Indian Cement Co. Ltd., was established at Porbander (Gujarat) and by 1914 this Company was able to deliver about1000 tons of Portland cement. By 1918 three factories were established.
