Production of clinker grinding of cement 2.1 Preparation of raw meal This is the stage where the main material (to the kiln) is prepared. Operating at Optimum Capacity frequent unplanned stoppages is fuel consumption for returning to normal kiln temperature without any clinker.
The clinker cooler exhaust is at a temperature near 200 C and is typically used for preheating the kiln or other parts of the clinker production process. The ORC and Kalina cycles have also been considered for use to recover the waste heat from the clinker cooler.
Raw material grinding and drying systems that use all or a portion of kiln gases for drying may accomplish substantial SO2 removal because of the nature of the process. with flame impingement on clinker, the clinker surface temperature can become high enough to thermally decompose sulfate salts. The optimum temperature is 800 900 C.
Heat is generated in the grinding of clinker, resulting in a rise of temperature which in some instances exceeds 120 c. The water content in gypsum is driven out, slowly at first, but above 80 C, at a rapid rate, as a result of which, gypsum is dehydrated and transformed into its hemi hydrate or anhydrite form.

In addition, clinkers that just complete the calcination will have a high temperature, thus a cooling machine is usually placed behind the rotary kiln so that the clinker can go directly into the cooler for dropping to normal temperature. Clinker Grinding is the final step in cement production. The cooled clinker is a kind of granular material.
