Cement process analysis system

 

Cement kiln is a big consumer of energy in industrial kilns. In the production process of dry rotary kiln, the analysis of gases such as kiln tail, decomposition furnace and outlet of pre-heater can optimize control, save energy, reduce CO2 emission. The analysis of gases in electric dust collection and coal grinding at kiln tail can protect the equipment safe operation.
