Air Pollution Control In The Cement Industry

2 Wet Process - Feed materials for the wet raw grinding circuit may involve materials stored relatively dry and, in the case of previously processed clay, in slip form at perhaps 60 - 70 moisture content. Emissions from the transfer of dry feed components to the mill are normally controlled by low temperature bag-type collectors.

Pdf Process Automation Of Cement Plant

Clinkers are created from the chemical reactions between the raw materials. The pyroprocessing takes place in a kiln. A kiln is the heart of any cement plant. It is basically a long cylindrical pipe which rotates in a horizontal position having 1600-1700 C temperature. The output of kiln is called clinker.
