Once cooled, clinker is ground with gypsum and other minerals, such as limestone, to produce the grey powder commonly recognised as cement. Changing the chemical composition of the raw mix enables cements with different properties to be produced for different uses.
2017-10-17 · 4 Due to the interaction of raw materials and kiln gases, rotary kiln systems have inherent SO2 removal efficiencies ranging between 40-99% of the sulfur input to the system. The literature suggests that 50-70% of the remaining SO2 will be removed from exhaust gases when passed through an in-line raw mill system....Chat Now
Clinker formation is a serious problem in boilers of thermal power plants which results in forced outage and generation loss. Removal of clinkers from the water wall is difficult thus requires pneumatic hammering. Low quality coal having less gross calorific value, high mineral content, high ash content, and the over-firing of molten slag are causes of clinker formation.

2018-10-10 · In this study, plant tests were performed to investigate the possibility to decrease the amount of Cr (VI) in clinker by having reducing conditions in the kiln. This was obtained by adding fuel oil to the cooler, pet coke to various positions in the preheater, and to kiln feed at various rates.
It is necessary to adapt the combustion process of the alternative fuel (AF), e.g. rice husk, in a cement kiln plant in order to achieve its complete combustion. In the case of incomplete combustion of the fuel, unburned carbon particles accumulate in the clinker, which has a detrimental effect on the clinker and cement properties [19, 20]....Chat Now
