GREAT WALL CEMENT ROTARY KILN MAKES BEST USE OF HOUSEHOLD GARBAGE
1. cement industry is able to clear and reusing various of waste material, the finished products have wide application
2. According to its property and character, different waste can be used for different cement industry products making. For example, admixtures, substituted material, alternative fuel, etc.
3. There a greatly demanding on the market for cement. The cement plants usually have large process scale. Cement kilns are designed with large capacity. So we think, it is considerable to use cement rotary kiln handling various waste in the near future.
4. Cement kilns have a strong adaptability for all kinds of combustible waste. By some adjusting, no affect will have to normal performance and qualify of cement. So does the kiln running and operation.
5. Cement kiln inner temperature is high(1600℃) with big thermal capacity and thermal inertia. The waste material can stay in the high temperature zone for 5-15seconds. Harmful ingredient can be completed decomposed to make sure an environment safety.
6. After burning in the kiln, all the harmful ingredient in the residue, such as, Si, Cl or heavy metal are also solid and melted in clinker lattice. Which avoid the second pollution.
7. All the thermal energy produced by burning combustible waste, can be directly used for the heat exchange process of gas solid phase and solid melt phase reaction.
8. cement kiln have good adapt range for heat value of combustible waste. Especially for the waste used as alternative material and alternative fuel, we can make the best use of their heat value for handling material of sludge and gangue.
