The raw mixture prepared is heated in large rotary kiln up to about 1400-1450 C. A series of chemical reaction occurs as the temperature rises. The peak temperature is maintained so that the material does not contain sinter products. Sintering is the process of melting the mass of the material.
Aug 30, 2012 Kiln is heating up from the exit side by the use of natural gas and coal. When material reaches the lower part of the kiln, it forms the shape of clinker. Cement Manufacturing Process Phase V Cooling and Final Grinding. After passing out from the kiln, clinkers are cooled by mean of forced air.

Rotary kiln operations. Regardless of rotary kiln size or configuration the basic principles outlined in this manual govern the reliable operation of every rotary kiln, calciner, dryer, incinerator, digester and cooler application. For questions or problems with your specific application please contact North American Kiln.
Rotary kiln. This is determined by (i) the maximum flow rate of the proposed burden through a kiln, and (ii) the residence time at temperatures that would allow sufficient reduction to take place. A calculation method was developed that allows for the prediction of the bed profile and residence time in a rotary kiln.
Rotary kiln incinerator or a rotary kiln dryer. The kiln is a cylindrical vessel, inclined slightly to the horizontal, which is . rotated slowly about its axis. The material to be processed is fed into the upper end of the cylinder. As the kiln rotates, material gradually moves down towards the lower end, and.
The flowsheet diagram of the wet process for manufacturing Portland cement is given in Figure 3.3.
