The cement production process begins with the extraction of limestone and clay from the quarry. The material is then blended, crushed and fed to the kiln. Postkiln, the clinker is cooled and goes through a final grinding method before it is ready to ship. Portland cement, the most common type of cement, is formulated in a variety of strengths ...

Raw mill exhaust fans or stack fans are also called as dedusting fans. In cement industry raw mill exhaust fans handle ton of exhaust gases for the production of 1 ton of clinker. Raw mill exhaust fans are operated with very adverse situations because the fan handles mainly gases such as CO2, N2, NOx and Sox along with some dust particles.

Extraction and processing. Raw materials employed in the manufacture of cement are extracted by quarrying in the case of hard rocks such as limestones, slates, and some shales, with the aid of blasting when necessary. Some deposits are mined by underground methods. Softer rocks such as chalk and clay can be dug directly by excavators.. The excavated materials are transported to the crushing ...
