The use of fly ash, slag, various tailings in cement production, and the use of natural raw materials from industrial waste are very common and have achieved considerable economic and social benefits. Hongke Heavy Industry after a lot of research and practice shows that cement rotary kiln is a unique treatment of hazardous waste incinerator. Cement rotary kiln combustion temperature is high, the material in the kiln for a long time, but also in a negative pressure state of operation, stable work, for a variety of toxic, flammable, corrosive, reactive hazardous waste has a good degradationRole, not to discharge waste residue. Residues in the incineration and most of the heavy metals are fixed in the cement clinker, will not produce secondary pollution to the environment.

8, flue gas temperature: <250C
The use of cement rotary kilns to ensure that the quality of cement products is not affected, because the cement kiln waste disposal is carried out in the cement production line, it is necessary to deal with the physical properties of waste and chemical control, Deployment process and final alternative fuels for analysis to regulate the performance of alternative fuels. To control the physical properties of waste include: calorific value, ash, sulfur, heavy metals and volatile, radioactive and so on.
