Raw Mill Kiln Application in Cement Industry Thermax

The rotary kiln is the heart of a cement manufacturing plant. Cement kilns have all chemical ingredients. These (ESP) for the control of particulate emissions from the kiln and raw mill. Since the existing circuit was designed in early 90’s for lower capacity of Kiln, CCCL wanted to look at the various alternatives to reduce the emissions
