The manufacture of Portland cement is a complex process and done in the following steps: grinding the raw materials, mixing them in certain proportions depending upon their purity and composition, and burning them to sintering in a kiln at a temperature of about 1350 to 1500 C. During this process, these materials partially fuse to form nodular shaped clinker by broking of chemical bonds of
Burning: In this operation, the slurry is directly fed into a long inclined steel cylinder called a Rotary this kiln there are 3 different zones shown in fig. below. Cement Manufacturing Process Flow Chart (i) Drying Zones: In the wet process, the drying zone is comparatively larger than the dry process. It is because the raw material in slurry form is directly fed into the kiln which
Mar 28, 2018#0183;#32;Wet process Mixing of Raw materials in wash mill with 35 to 50% water. Materials exiting the mill are called quot;slurryquot; and have flowability characteristics. Size of the kiln needed for manufacturing of cement is bigger. Raw material can be mixed easily, so a better homogeneous material can be obtained Fuel consumption is high,
Aug 17, 1971#0183;#32; Portland Cement Manufacturing Process Description17 Portland cement is a fine powder, gray or white in color, that consists of a mixture of hydraulic cement materials comprising primarily calcium silicates, aluminates and aluminoferrites. More than 30 raw materials are known to be used in the manufacture of portland cement, and these
The total consumption of coal in this method is only about 100 kg when compared to the requirement of about 220 kg for producing a ton of cement in the wet process. The dry material undergoes a series of chemical reactions in the hottest part of the kiln and some 20 to 30 percent of the material becomes liquid, and lime, silica and alumina
Jun 21, 2016#0183;#32;The kiln has to operate continuously in order to ensure a steady regime, and therefore uniformity of clinker. The larger existing kiln in a wet process plant produces 3600 tonnes of clinker per day. The manufacture of cement by wet process is energy intensive and thus uneconomical as compared to dry process and semi dry process.

The following flow sheet shows the details of the wet process in the manufacture of cement The dry process for manufacturing. In this process, the raw materials dried and ground to a fine powder by grinding mill. The dry powder is then further blende and corrected for its right composition and mixed by means of compressed air.
Cement Manufacturing Process Flow Chart. (i) Drying Zones: In the wet process, the drying zone is comparatively larger than the dry process. It is because the raw material in slurry form is directly fed
The wet process of cement manufacturing refers to grinding raw material into slurry after mixing with water and then feeding them into the wet process kiln for drying and calcination and finally forming clinker. The slurrys water content is usually between 32%36%.
Dec 13, 2018#0183;#32;Wet Process. The specific feature of the wet process is that the raw materials are prepared in water whereas in the dry process the materials are ground and mixed dry. The flowsheet diagram of the wet process for manufacturing Portland cement is given in Figure The limestone is disintegrated in crushers.
Aug 30, 2012#0183;#32;The remaining cement is shipped in bulk quantities by mean of trucks, rails or ships. Cement Manufacturing Process Flow Chart. After explaining the complete process of cement making, flow chart would be like that. flow chart present the summary of whole process
The process out clinker is cooled and ground to a fine powder with the addition of about 3 to 5% of gypsum. The material produced by this process known as Portland cement. The cement manufacturing is done by majorly by two methods known as wet process and dry process
