Raw Material Processing. Processing raw materials is one of the essentials in a cement plant, some of the processes that might be needed to get the raw material into perfect shape includes; blasting, crushing and milling. The most common raw materials include limestone sand, PFA and ironstone. Making the best use of these raw materials is

Cement Production Process Clinker and cement production is an intensive process in terms of natural raw material and energy input. Limestone (primary source of calcium carbonate CaCO 3 ) and clay (primary source of silica SiO 2 , alumina Al 2 O 3 and iron oxide Fe 2 O 3 ) are typically mined in company-owned quarries and pre-blended to a target chemical material composition.

To produce one ton of cement clinker, it needs to consume 1.58 to 1.621 tons of raw materials, 0.10-0.12 tons of coal, and emit about 1 ton of carbon dioxide. Therefore, the energy saving and consumption reduction in the clinker calcination process is crucial for the whole cement production line. The above is the thermal performance test data
