In cement production processes, there are several models for the purpose of studying the use of alternative fuels 4, 36, 39 phase chemistry , oxidation process of coal tar pitch , cement raw material blending process , reduction of CO 2 , sensitivity analysis of a model used for the design of rotary kiln processes , and a nonlinear model .
Clinker Burning - Supreme Discipline in Cement Production. If clinker is not the best, cement can never be good. Clinker quality has the biggest impact on cement quality. And the clinker burning process determines, as well as raw meal, the quality of clinker. Clinker burning process is the cement production step with the highest cost.
2015-5-5ensp0183enspA simplified illustration of oxygen-enriched air combustion is shown in Figure 1.The idea is to add highly concentrated oxygen to the process, with the aim of increasing the production of cement clinker for sustainability purposes such as enhancing the combustion of low-grade fuels or improving energy efficiency Damtoft et al., 2008.
To achieve the combustion of only slightly treated waste fuels and substitute fuels in a rotary kiln for cement production, the substitute fuel is fed into the calcining zone of the rotary kiln which, for this purpose, has on its outside in this zone at least one fuel pick-up.
2019-3-25ensp0183ensp4 In the calculation of the production loss of the complete cement production line and clinker production line, the production loss of coal should be calculated at 2.0, and the production loss of other materials should be calculated at 0.5. The production loss of all materials in the cement grinding station shall be calculated at 0.5.

2012-9-12ensp0183ensp dry-process cement production process. drying and grinding raw materials together, or first dried by grinding the raw material powder feeding dry kiln burning mature. But people also the raw material powder ball made of raw material, adding an appropriate amount of water fed into the kiln burning mature Lepol method, called semi-dry, it is still a kind of dry method production.
Cement production processes can be categorized as dry, semidry, semiwet, and wet processes depending on the handling of raw material before being fed to the rotary kiln.
The main power consumption of a clinker cooler is its cooling fans. It usually takes 1.9-2.3 m 3 under standard conditions to cool 1 kg clinker from 1400 to 65 , and the power consumption of the whole system is about 7 kWh. If the air consumption per kilogram of clinker cooling is reduced from 2 m 3 to 1.
Wet process kilns. The original rotary cement kilns were called wet process kilns. In their basic form they were relatively simple compared with modern developments. The raw meal was supplied at ambient temperature in the form of a slurry. A wet process kiln may be up to 200m long and 6m in diameter.
