Cement manufacturing components of a cement plant

Cement manufacturing components of a cement plant

Cement is typically made from limestone and clay or shale. These raw materials are extracted from the quarry crushed to a very fine powder and then blended in the correct proportions. This blended raw material is called the 'raw feed' or 'kiln feed' and is heated in a rotary kiln where it reaches a temperature of about 1400 C to 1500 C.

Emissions from the Cement Industry

Emissions from the Cement Industry

May 09, 2012 Cement manufacturing is highly energy- and emissions-intensive because of the extreme heat required to produce it. Producing a ton of cement requires 4.7 million BTU of energy, equivalent to about 400 pounds of coal, and generates nearly a ton of CO 2. Given its high emissions and critical importance to society, cement is an obvious place to ...
