A lot of garbage has caused serious damage to our ecological environment, which takes up large tracts of land, and also pollutes our water and air. Serious impact on the environment of the city brings a huge threat to the health of residents of the city.  In order to solve the cement consumption and environmental problems caused by a huge increase in waste and solid waste, all countries in the world starts to use cement rotary kiln to dispose of and make use of waste, to reduce the cement waste pollution to the environment.

The waste disposal by cement rotary kiln is one of the more recent garbage waste way. Using cement rotary kiln incineration of garbage litter has a large number of successful practices in the world and prevents secondary pollution, with great economy. Waste disposal of thoroughness shows great advantages in many aspects.First of all, the temperature of cement rotary kiln is high, temperature of  the flue gas and material can respectively reach 1750 ℃and 1450 ℃; Second, the residence time for cement rotary kiln in the flue gas is long,  material stays alone more than 4 s  in the temperature of  flue gas higher than 1100 ℃and the roll is  advantageous to the hazardous waste burned completely; In addition, parts of combustible hazardous waste can be used as a fuel, clinker burning through full combustion can be broken down into harmless gas; Harmful dust in flue gas preheater dust collector of the rotary kiln processing can achieve safety discharge standards.

Cement rotary kiln can make most of heavy metals of waste fixed in the clinker to prevent the spread of again; burning waste residue is mixed with cement clinker into the cement products, and has no longer generate secondary pollution to the environment. So using cement rotary kiln to dispose of hazardous waste is one of the most thorough and most economical ways.
