3000°F in the kiln. Rotary kilns are divided into two groups, dryprocess and wetprocess, depending on how the raw materials are prepared. In wetprocess kilns, raw materials are fed into the kiln as a slurry with a moisture content of 30 to 40 percent. To evaporate the water contained in the feedstock, a wetprocess

Cement kiln Wikipedia

For this reason it was the system of choice for older kilns. A disadvantage is that the fuel mill has to run all the time: if it breaks down, the kiln has to stop if no backup system is available. In indirect firing, the fuel is ground by an intermittently run mill, and the fine product is stored in a silo of sufficient size to supply the kiln ...

The cement industry is one of the most intensive energy consumers in the industrial sectors. The energy consumption represents 40% to 60% of production cost. Additionally, the cement industry contributes around 5% to 8% of all manmade CO₂ emissions. Physiochemical and thermochemical reactions involved in cement kilns are still not well understood because of their complexity. The ...

Rawmill Wikipedia

A mediumsized dry process roller mill. A raw mill is the equipment used to grind raw materials into "rawmix" during the manufacture of cement. Rawmix is then fed to a cement kiln, which transforms it into clinker, which is then ground to make cement in the cement raw milling stage of the process effectively defines the chemistry (and therefore physical properties) of the finished ...
