Cement production needs to consume a large amount of non-renewable natural resources. This characteristic restricts the sustainable development of cement industry. While many cement enterprises are at a disadvantage in market competition due to the lack of mineral resources and the high product cost, which restrict the survival and development of these enterprises. How to change the bad situation, walk out of predicament, uses wastes instead of the original fuel in cement production, reduce the consumption of natural minerals, take advantage of the characteristics of cement kilns, dispose industrial hazardous waste, and strengthen environmental affinity, is the direction of the sustainable development of cement enterprises.

Cement Kiln Waste Treatment Advantage

Cement production using fly ash and a variety of wastes as an alternative has been very common, and it has achieved great economic benefits and social benefits. Through a lot of research and practice, people realize the cement rotary kiln is a unique treatment of hazardous waste incinerator.

Cement kiln combustion temperature is high, the material in the kiln stay a long time, and is running the vacuum state. Under stable working conditions, it can have a good degradation on hazardous waste that has a variety of toxic, flammable, corrosive. It does not discharge waste outside. Burning things and most of the heavy metals in the residues are fixed in cement clinker, thus it does not produce secondary pollution to the environment. Using RDF technology to hand garbage is another potential of cement kiln. In Germany, Japan and other developed countries, it has been widely adopted. Through garbage crushing, screening and other means, it can separate and treat the combustible material in the garbage. Combustible material serves as the fuel of cement plants, steel plants, chemical plants, power plants. Among which cement plants use the most efficiently. RDF not only replaces some of fuel, but also combustion ash is utilized as a cement raw material. Therefore, it is an effective garbage treatment for the use of cement kiln.

Cement Kiln Attention

Since the disposal of waste is carried out in cement kilns in cement production process. In order to ensure product quality and cement production process not affected, people must take control of physical and chemical properties of waste.

Expertise and management requirement that waste treatment especially hazardous waste treatment needs is not the same with traditional cement production. So the professional requirements are not the same. Therefore, it needs to introduce the relevant professional and technical personnel, strengthen corporate staff training, improve operational capacity, and enhance safety awareness. Whether the ability of employees can meet the requirements of this work is an important factor in the success.
